2. Introduction
The R5000 SwitchMaster®Switching System is a 2U 19” rack style chassis containing multiple A/B Switch Cards.
Each switch card connects port A or port B to port C, through latching or non-latching telecommunication relays or
fiber optic switch mechanisms. For models using latching mechanisms, the connection state will be maintained if
power fails or is removed. Non-latching versions will revert to the port C to port A connection state when power is
lost, and will remain in that state when power is restored until a new switch command is received. Pseudo Non-
latching fiber optic switch cards fall back to the “Port C to Port A” connection when power fails or is removed.
When power is re-applied, the optical switch in a pseudo non-latching fiber optic switch card will reconnect port C
to the port (A or B) that was selected prior to the loss of power. The non-latching styles of fiber optic switch cards
are often used when a fall-back or “failover” style of connection scheme is desired in the event of power failure.
The R5000 rack has 18 slots and can accept any mix of switch cards, power supply cards, and one Controller Card
(one required per chassis). Any type of card can be installed in any slot in the R5000 rack, allowing for maximum
flexibility of cable routing etc. If a single slot power supply card (such as the 5100740) is used, the rack can hold up
to 16 A/B Switch Cards, and a Controller Card. Each A/B Switch Card can be individually switched, or the entire
rack can be switched from the Controller Card. The Controller Card has a keyed switch to enable and disable
manual switching (disables the front panel toggle switches on the Controller Card and on each switch card). The
Controller Card has two RJ11 ports which provide for serial communications to the rack, and also allow multiple
racks to be daisy-chained together to create a single system that can be controlled by the first rack in the daisy chain.
The Controller Card also provides remote switching capabilities via an RS232 interface or using a +/-12 VDC signal
from a remote toggle switch.
The Controller Card consists of a front pc board assembly and a rear pc board assembly set, and is available in three
different versions (RS232, SNMP/Ethernet, and SNMP Expansion). The RS232 version supports Rack and System
Gang Switching using the manual toggle switches on the Controller Card and A/B Switch Cards, and supports RS232
communicationson the gang-in and gang-out connectors. The RS232 Controller Card allows system level (all cards
in all racks) switching with serial commands (see section 5.1 for additional info).The SNMP/Ethernet capable
version features a RS232 terminal interface which can be used to control individual A/B switch cards, a rack of A/B
switch cards, or system of daisy-chained racks, and to configure the Ethernet port parameters (see section 7 for
additional info). The Ethernet port allows the rack or system of daisy-chained racks (containing the SNMP
Expansion Controller Card) to be controlled using SNMP commands, Telnet commands, or via a built-in html based
web browser interface. There can only be one SNMP/Ethernet capable Controller Card in a daisy-chained system of
racks, and it must be in the first rack in the system. If daisy-chaining one or more racks from an SNMP/Ethernet
capable rack, the additional racks must have an SNMP Expansion Controller Card, which is compatible with the
message format from the SNMP/Ethernet Controller Card.
The SNMP/Ethernet Controller Cards also support SNMP traps or syslog messages (user configurable) for various
events and errors, and can send these alerts to as many as 16 different remote monitoring locations.
The SNMP/Ethernet Controller Cards have an intelligent automatic switching capability. This feature allows the
switching system to be used to monitor a specific Ethernet network connection and to automatically switch all ports
(performs a system switch operation) based on whether the monitored IP address responds to ICMP echo requests
(responds to PINGs) or not. See section 5.5 for additional details.
The DB25 Signal Monitoring switch cards are described in a separate manual.

3. Configuration
3.1 A/B Switch Card Configuration
Figure 3.1.1 –Typical A/B Switch Card Front & Rear Panels
Each A/B Switch Card has an 8-position DIP switch, used to set the card’s address. Switch position 1 is the least
significant bit, and position 8 is the most significant bit. Set each switch ON (as marked) for a '0', and OFF for a '1'.
Card address 1 for example, would be DIP switch position 1 OFF, and positions 2-8 ON. Card addresses within a
rack, or within a system of daisy-chained racks must be unique and one card MUST be addressed 1. Card address
0x00 is reserved and must not be used. A typical approach is to set rack 0x01, card addresses to 0x01 through 0x10
from left to right within the rack. In the second rack 0x02, set the card addresses to 0x11 through 0x20 and so on.
The Controller Card communicates with the individual switch cards using a multi-drop scheme. If two A/B cards
within the same rack or daisy-chained system of racks have the same address, both will try to respond at the same
time, causing communication errors. Thus, the maximum number of A/B Switch Cards in a daisy-chained system of
racks is limited to 255 switch cards.

The Controller Card rear pc board assembly has two jumpers for shielding and grounding options. The two 3-
position jumpers are positioned such that pin 1 is toward the card edge connector, and pin 3 is toward the RJ11
connectors. Each 3-position jumper has a 2-position shunt, used to connect two of the three positions together.

configured as TXD and RXD for serial communication, or as V+ and V-to control the system control input with a
remote toggle switch. The connections to V+ and V-are through 1 K ohm resistors. The System Control signal is
used as an input and an output. As an Input signal it is normally open. This input is driven to +12 VDC to switch
the system to A, and is driven to –12 VDC to switch the system to B. As an output, this signal is driven to +10 VDC
when the user initiates a system switch to A, and is driven to –10 VDC when the user initiates a system switch to B.

3.3 Controller Card Front PC Board Configuration
The Controller Card front pc board has an 8-position dipswitch and four jumpers for user configurable options. The
four 3-position jumpers are positioned such that pin 1 is toward the front panel, and pin 3 is toward the rear of the
card. Each 3-position jumper has a 2-position shunt, used to connect two of the three positions together.

Jumpers W1 and W2 function as a pair to configure the gang-in port. Refer to table 3.2.3 for the GANG-IN port pin
assignment. Connect to TXD and RXD to support RS-232 serial communications, or connect to V+ and V-through
1 K ohm resistors to control the system control input with a remote toggle switch. Note that the serial port is
required for setup of the network parameters.

Jumpers W4 and W5 function as a pair to configure the input port source. It should not be necessary to change these
jumpers from their factory set positions. These jumpers configure the source for communications to the internal
processor on the Controller Card. If you have a Controller Card with an optional SNMP/Ethernet module installed,
both jumpers should be set to connect pins 2 and 3. Otherwise both jumpers should be set to connect pins 1 and 2 to
allow the processor to communicate with the RS-232 signals from the GANG-IN port.
The 8-position dipswitch has a different function depending on the type of Controller Card. Refer to Table 3.3.3 for
the RS232 version only.
For the SNMP/Ethernet and SNMP Expansion Controller Cards, the 8-position dipswitch SW2 is used to define the
Controller Card (or rack) address. Rack addresses within the system must be unique, but may be repeated in other
systems. The rack address space and card address space are separate, i.e. racks and cards can have the same address.
It is necessary that address “00” be left unused, and recommended that the racks be assigned addresses “01” through
“FF”. If two racks within the same system have the same address, both will try to respond at the same time, causing
communication errors. Switch position 1 is the least significant bit, and position 8 is the most significant bit. Set
each switch ON (as marked) for a '0', and OFF for a '1'. Address 1 for example would be position 1 OFF, and
positions 2-8 ON.
The SNMP/Ethernet Controller Cards can be supplied with special “universal” firmware that allows the Ethernet
management interface to be enabled or disabled depending on the address DIP switch setting. When the rack
address DIP switch is set to address “1” (binary 00000001), the Ethernet interface is enabled and the unit operates as
a normal SNMP/Ethernet Controller Card. If the rack address DIP switch is set to address 2 or higher, the Ethernet
interface is disabled and the unit operates like a SNMP Expansion Controller Cards, allowing it to be daisy-chain
connected to the GANG-OUT port of another SNMP/Ethernet or SNMP Expansion Controller Card. Please contact
Market Central for additional information regarding the universal firmware.

When the security code is enabled (SW2-5 set to ON), the selected security character must precede any serial
commands received at the gang in port of the first rack in the system. The security code must be disabled on all
following racks. Refer to section 5.1 for a list of applicable serial commands.
Safe mode operation (SW2-6 set to ON) prevents switching commands from the gang-in port, allowing only status
request commands. This provides a level of protection against corrupt or spurious data causing unintended switching
in an application where only status is required of the gang-in port. Set safe mode OFF to allow A/B switching from
the gang-in serial port. Safe mode must be disabled (OFF) on racks connected to the gang-out port of another R5000
rack, to allow system switching to occur (otherwise system switching will be blocked from higher level racks).
Dip switch positions 7 and 8 are reserved for future development, and should be left in the OFF position.

4. Installation
The A/B Switch Cards consist of a single card, which is inserted from the rear of the rack. The Controller Card
consists of a front card and a rear card.
4.1 Controller Card Rear PC Board Installation
4.1.1 Using the card guides, carefully slide the rear card into the rack, until it makes connection to the 8-position
socket on the rack backplane.
4.1.2 Secure the rear card to the rack at the top and bottom of the card, using the screws provided.
4.1.3 Using standard RJ11 male/male crossover cable, connect the gang out from one rack to the gang in connector
on the next if multiple racks are to be daisy-chained together. Repeat this step until all racks have been
connected.
4.2 Controller Card Front PC Board Installation
4.2.1 Using the card guides, carefully slide the front card into the rack, until it makes connection to the 36-position
card edge connector on the rear card.
4.2.2 Secure the front card to the rack at the top and bottom of the card, using the screws provided.
4.3 A/B Switch Card Installation
4.3.1 From the rear of the rack, using the card guides, carefully slide the card into the rack, until it makes
connection to the 8-position socket on the rack backplane.
4.3.2 Secure the rear card to the rack at the top and bottom of the card, using the screws provided.
4.3.3 If not already in place, secure the front panel to the rack, using the screws provided.
5. Operation
When power is applied to the Controller Card, the PWR LED should illuminate.
When power is applied to the A/B Switch Card, either the "A" LED or the "B" LED should illuminate to indicate the
currently connected port.
When the Key-Lock switch on the Controller Card is OFF, the manual toggle switches on the Controller Card and all
the A/B Switch Cards in the rack will be disabled. Note that the rack may still switch in response to a command
received on the RS232 Gang-In port, or the Ethernet port.
When the Key-Lock switch on the Controller Card is ON, the manual toggle switches in the rack function normally.
The toggle switches on the A/B Switch Cards are used to switch only that card. Hold the switch in the “A” position
to connect Port A to Port C. The “A” LED will illuminate when the switch operation has been completed. Release
the switch when switching has finished. Hold the switch in the “B” position to connect Port B to Port C. The “B”
LED will illuminate when the switch operation has been completed. Release the switch when switching has finished.
The toggle switch on the Controller Card is used to switch all cards in the rack, and is operated in the same fashion
as the individual toggle switches on the A/B Switch Cards. To switch an entire system of daisy-chained racks, hold
the “system” push-button while operating the toggle switch on the Controller Card.
The Controller Card STAT LED should blink under the following conditions:
The front panel control switches are used to initiate a “rack” or “system” level switching operation.
The Controller Card received a switch command on the RS232 Gang-In port or the Ethernet port.

5.1 RS-232 Serial Switching
The RS232 version of the Controller Card allows the user to remotely switch all of the cards in a rack or system of
daisy-chained racks using the serial commands listed in Table 5.1.1 below. The SNMP/Ethernet version of the
Controller Card does not support the one character serial commands listed in Table 5.1.1 below, but instead uses the
enhanced console commands listed in Section 7 of this manual. Also note that the data rate of the Gang-In port
increases to 9600 bps for the SNMP/Ethernet version of Controller Card. The SNMP Expansion Controller Card
does not support the one character serial commands listed in Table 5.1.1 below, but will pass these commands
through to the cards in the rack and to subsequent racks in the system.
Table 5.1.1 –RS-232 System Switching Commands (RS232 version of Controller Card)
Command Description
A <CR> Switch “system” to A
B <CR> Switch “system” to B
S <CR> Request “status”
Notes:
1. The RS232 terminal device connected to the RS232 version of Controller Card’s Gang-In port must be set to
2400 Baud, No Parity, 8 Data Bits, 1 Stop Bit. Connect using the supplied DB9 to RJ11 adapter and RJ11 to
RJ11 crossover cable.
2. The one character commands above are CASE SENSITIVE, and must be followed by a carriage return. Refer
to table 3.3.3 for a list of optional “security” characters which may precede these commands.
3. Note: These RS232 commands only allow control of the entire system, thus the status of all cards in the system
should be the same. Therefore, only one card (address 0x01) in the first rack will respond to the “S” status
command. If there is no card with address 0x01 in the first rack, there will be no response to the status
command.
5.2 “SYSTEM” Switching Using the Gang-In System Control Signal
The System Control signal is used as an input and an output. As an Input signal it is normally open. This input is
driven to +12 VDC to switch the system to A, and is driven to –12 VDC to switch the system to B. The input circuit
requires approximately 1 mA to operate properly.
As an output, this signal is driven to +10 VDC when the user initiates a system switch to A, and is driven to –10
VDC when the user initiates a system switch to B. To protect the output circuits, the output goes through a 1 K ohm
resistor. Therefore, this output should not be used to drive a large load.
The gang-in connector normally accepts RS-232 input signals, but can be configured to supply +12 VDC and –12
VDC. Refer to table 3.3.1 for jumper configuration information. These +12 VDC and –12 VDC outputs are
provided through 1 K ohm resistors, and therefore should not be used to drive large loads. These outputs are
provided to allow system switching, using only a remote contact. It is recommended that a momentary toggle switch
be used.

5.3 RS232 Console Commands (for SNMP/Ethernet Controller Card)
This section is applicable to SNMP/Ethernet Controller Cards. The GANG-IN RS232 interface on the
SNMP/Ethernet Controller Card operates at 9600.The GANG OUT interface operatesat 2400 bps. This allows the
GANG OUT interface to connect to the GANG IN port on another R5000 (that does not have the Ethernet Module
installed) so that multiple racks can be daisy-chain connected together. When daisy chaining multiple racks, only the
first rack in the chain may have an Ethernet Module installed.
SNMP/Ethernet Controller Cards support an enhanced set of serial commands that are listed below and described in
more detail in section 7. To communicate with the internal Ethernet module, set your RS232 terminal to 9600 baud,
no parity, 8 data bits, and 1 stop bit. Connect this terminal to the GANG-IN RS232 interface on the SNMP/Ethernet
Controller Card using the DB9 to RJ11 adapter and RJ11 crossover cable provided with the SNMP/Ethernet
Controller Card.
When you apply power to the system, the Ethernet module runs a series of internal self tests and configuration steps.
This takes approximately 5 seconds. After this process is complete you will see a sign-on message displayed on your
serial console, similar to the following:

5.4 Remote Ethernet Management (for SNMP/Ethernet Controller Card)
In order to use the Ethernet network port you must set the IPADDRESS, SUBNETMASK and GATEWAY address
of the internal Ethernet module before connecting to your network. See section 6 for more details.
The internal Ethernet module allows remote management of the switching system via SNMP, Telnet, or web
browser. The SNMP interface allows access to the MIB variables described in section 9. SNMP is also used by
SwitchCenter the java based graphical user interface application provided with the SNMP/Ethernet Controller Card.
The Telnet and web browser interfaces provide access to the console commands described in section 7. Each of
these remote management interfaces may be enabled or disabled.
The SAVE command is used to cause the internal Ethernet module to store the configuration parameters in non-
volatile memory. If the Ethernet module is reset prior to performing a SAVE command, configuration changes will
be lost.
5.5 Automatic Switching (for SNMP/Ethernet Controller Card)
The SNMP/Ethernet Controller Card can be configured to automatically switch the connection state (all COMMON
ports are connected to their respective A ports) or (all COMMON ports are connected to their respective B ports). In
order to be able to perform the auto-switching functions, the internal Ethernet module issues ICMP echo request
(PING) packets to a user configurable IP address on the network.
The auto-switching function can be configured to operate in one of two modes. In FAILOVER mode (the default
mode), the auto-switching function switches to the “failover” or “bypass” connection state (all COMMON ports are
connected to their respective A ports) when PING responses are not received, and if configured to “auto recover” it
switches to the “normal” connection state (all COMMON ports are connected to their respective B ports) when
PING responses are received. In TOGGLE mode, the auto-switching function toggles the connection state from A to
B or from B to A when PING responses are not received, and maintains the connection state all COMMON ports are
connected to their respective A ports or B ports when PING responses are received. User configurable parameters
control the auto-switching functions to allow the switch to be used in a variety of applications.
In FAILOVER mode, if the “normal” network path connections between the Ethernet module and the device being
monitored go down for any reason, the Ethernet module will no longer be able to PING the specified IP address, and
will then automatically switch from the “normal” connection state (all COMMON ports are connected to their
respective B ports) to the “bypass” or “failover” connection state (all COMMON ports are connected to their
respective A ports). Once the problems on the primary path have been identified and corrected, the user can issue a
command to cause the R5000 to switch from the failover connection state back to the normal connection state. If
auto recovery is enabled, the Ethernet module will automatically re-connect the normal path connections when it is
again able to PING the user specified IP address. When using the auto recovery feature, it is important that the
Ethernet network port on the R5000 be connected to the user’s network such that the normal path is continuously
being monitored even when the backup path has been selected, otherwise the R5000 could repeatedly switch (flap)
back and forth between the failed primary path and the functioning backup path.
In TOGGLE mode, if the “current” network path connections between the Ethernet module and the device being
monitored go down for any reason, the Ethernet module will no longer be able to PING the specified IP address, and
will then automatically switch to the “alternate” connection state, trying to restore successful PING responses. In
this mode, the auto-switching function will toggle between (all COMMON ports are connected to their respective A
ports) and (all COMMON ports are connected to their respective B ports), until it receives responses to its PING
requests. The R5000 will then remain in the current connection state (all COMMON ports are connected to their
respective A ports or B ports), until the user issues a command to cause the R5000 to switch connections, or should
the Ethernet module fail to receive PING responses. When in TOGGLE mode, it is important that the R5000
Ethernet network port be connected to the user’s network such that the current path is being monitored.
See the diagrams below for examples of auto switching configurations.

R5000 A/B SWITCHING SYSTEM Page 13 of 28
When the auto switching feature is enabled, manual and remote switching can still be performed using the front panel
toggle switch or by issuing serial or Ethernet commands, but this can affect the operation of the automatic switching
feature. This is because the automatic switching feature is only aware of “system level” commands, i.e. “SET
SYSTEM A”, “SET SYSTEM B”, and manual switching using the front panel toggle switch while holding in the
“SYSTEM” pushbutton switch. If the user initiates any of these “system level” commands, the switching system will
execute the command and the automatic switching feature will record the new connection state. The automatic
switching feature will then continue to monitor the connection path to the selected IP address and will automatically
switch connections as it normally would.
However, if the switching system receives a “SET RACK” command, or if the rack is switched using the front panel
toggle switch without holding in the “SYSTEM” pushbutton switch, these commands will not be recorded by the
automatic switching feature -it will be unaware that the switching system has changed connection states. Under
certain conditions when in this state, the automatic switching feature will not automatically switch connection states
as expected, because it “thinks” that it is already in the correct connection state. To recover from this condition the
user can either power cycle the SNMP/Ethernet Controller Card, issue a “RESET” command, or execute a “system
level” command. Any of these actions will cause the automatic switching feature to record the current connection
state of the switch, which then allows it to again operate normally.
Connection changes made using the “SET PORT” command also are not recorded by the automatic switching
feature. Thus under certain conditions, the automatic switching feature will not automatically switch connection
states as described above when “rack level” commands are issued.

Note: The R5000 monitors the WAN connections by PINGing the far side router thru the primary WAN link. In FAILOVER mode, if

prevent flapping. In TOGGLE mode, if the selected WAN link fails, the R5000 will toggle between the primary and backup WAN until

In most network environments, you can configure the Ethernet module to automatically determine the proper MAC
address required for the PING packet. Enter the monitorip address of the device to be monitored, and leave the
monitormac address parameter set to the default value 00 00 00 00 00 00. This causes the Ethernet module to issue
an ARP request to determine the appropriate MAC address for the PING packet. To eliminate the ARP request,
enter the monitormac address as follows. If the monitored device is on the same subnet as the Ethernet module, set
the monitormac address to the MAC address of the monitored device. If the monitored device is on a different
subnet than the Ethernet module, set the monitormac address to the MAC address of the gateway router, so the
gateway router can route the PING packet to the target device on a different subnet.
6. Network Setup
To perform the initial setup of an SNMP/Ethernet version of Controller Card, you will need a serial terminal capable
of 9600 baud, no parity, 8 data bits, and 1 stop bit. Connect this terminal to the GANG-IN port using the supplied
DB9 to RJ11 adapter and RJ11 to RJ11 crossover cable.

Apply power to the R5000 rack. The SNMP/Ethernet version of Controller Card requires about 5 seconds to boot
up, while performing self tests and configuring.
After this process is complete you will see a sign-on message displayed on the serial console, i.e.

At this point the Controller Card is ready for the low level configurations necessary before you will be able to
communicate with the network port using TCP/IP. You will need to enter an IP address, subnet mask, and gateway
address, as well as read and write SNMP community names if using SNMP, a telnet password for telnet access, or a
web password for browser access. These parameters must be saved into non-volatile memory, and then the system

they must be saved followed by a system reset. The following shows a typical setup session. Change the entered
parameters to suit your application requirements. All the console level commands available are described in detail in
section 7.

After the system reinitializes, you will again be greeted by the sign-on message as before. At this time you can attach
a 10base-T CAT5 cable between the Controller Card’s Network port and an available port on your Ethernet hub or
switch/router. The SNMP/Ethernet version of Controller Card will now respond to telnet, SNMP and/or HTTP
messages at the assigned IP address depending on which options are enabled.Section 7 describes the commands that
are available via the console prompt (telnet, web, or RS232 interface). Section 8 describes the operation of the web
browser interface, and Section 9 provides a MIB Path Summary that lists the supported SNMP variables and their
functions.
7. Console Commands (SNMP/Ethernet version of Controller Card)
When the R5000 powers up, it will send a sign-on message followed by a prompt character “>” to your serial
terminal device, set at 9600 baud, no parity, 8 data bits, and 1 stop bit. After each command is executed, the
associated response from the R5000 will be issued followed by a prompt character. For systems where the console
port is being commanded by software, the software should wait for this prompt character before sending each and
every command to the R5000.
It is possible to switch one or all of the switch ports to the A or B connection state using the appropriate serial
commands. It is also possible to query the position of any one of the switch ports in a particular rack using serial
commands. The RS232 serial interface is NOT affected by the position of the front panel keylock switch –it will act
upon and respond to commands it receives even if the keylock switch is in the DISABLE position.
The following commands are available from the RS232 console prompt of an SNMP/Ethernet version of Controller
Card. All commands are case insensitive, although several variable parameters are case sensitive (read/write
community names, telnet and web password). All commands must be terminated with a carriage return (ASCII 13 or
hex 0x0D) before they will be processed. GET, SET, SYSTEM, RACK, PORT, and ALL can all be abbreviated by
the first letter of the command, allowing shorthand entry of switching commands.

SET MONITORIP [X.X.X.X]
GET MONITORIP
Set or display the IP address of the device that the Ethernet module is to PING to determine the appropriate auto-
switching action. Setting this to 0.0.0.0 disables the auto-switching function.Any change will not become
permanent until a SAVE operation is performed. When the auto-switching function is enabled, the Ethernet module
will send PING packets to the specified MONITORIP address and perform auto-switching actions dependent on the
selected MONITORMODE and dependent on weather or not the PING responses are received.
SET MONITORMAC [X X X X X X]
GET MONITORMAC
Set or display the MAC (Ethernet) address of the device that the Ethernet module is to PING to determine the
appropriate auto-switching action. This value is entered as a series of six HEX characters with spaces between each
HEX character. If the MONITORMAC address is set to 00 00 00 00 00 00, the Ethernet module will automatically
determine the proper MAC address required for the PING packet by issuing an ARP request. You can also manually
set the MONITORMAC address. If monitoring connectivity to a device on the same subnet as the Ethernet module,
set the MONITORMAC address parameters to the MAC address of the device being monitored. If monitoring
connectivity to a device on a different subnet/network than the Ethernet module, set the MONITORMAC address
parameter to the MAC address of the gateway router on the Ethernet module subnet. Any change will not become
permanent until a SAVE operation is performed.
SET MONITORINTERVAL [N]
GET MONITORINTERVAL
Set or display the time interval between PINGs issued by the internal Ethernet module, measured in 100 msec
increments. To issue PINGs every 1.5 seconds, set this value to 15. The valid range is 1 to 255 (0.1 seconds to 25.5
seconds). A value of 0 disables the auto-switching function. Any change will not become permanent until a SAVE
operation is performed.
SET MONITORFAILCOUNT [N]
GET MONITORFAILCOUNT
Set or display the Monitor Fail Count. In FAILOVER mode, this is the number of successive PING attempts that
must fail before the Switching System automatically switches to the “failover” or “bypass” connection state (all
COMMON ports are connected to their respective A ports). The valid range is 1 to 255. A value of 0 disables the
automatic switch/recovery function. In TOGGLE mode, this is the number of successive PING attempts that must
fail before the Switching System automatically toggles the connection state (A to B, or B to A); see also Monitor
Delay Count. Any change will not become permanent until a SAVE operation is performed.

Market Central, Inc.
R5000 A/B SWITCHING SYSTEM Page 19 of 28
SET MONITOROKCOUNT [N]
GET MONITOROKCOUNT
Set or display the Monitor OK Count. This parameter is not used in TOGGLE mode. In FAILOVER mode, this is
the number of successive PING attempts that must succeed before the Switching System automatically switches to
the “normal”connection state (all COMMON ports are connected to their respective B ports). The valid range is 1
to 255. A value of 0 disables only the automatic recovery function –automatic switching will still operate if
enabled. If auto recovery is disabled the user must manually switch back to the normal path via the front panel
switch or by issuing a “SET SYSTEM B” command.Any change will not become permanent until a SAVE
operation is performed.
SET MONITORDELAYCOUNT [N]
GET MONITORDELAYCOUNT
Set or display the Monitor Delay Count. This parameter is not used in FAILOVER mode. In TOGGLE mode, this
is the number of successive PING attempts which are ignored after toggling the connection state. This can be
thought of as a “blank-time” after a switching action to allow the new connection to be established. If the Monitor
Delay Count is set to a non-zero value, and the new connection state is also “down”, the Ethernet module attempts to
PING MONITORDELAYCOUNT (ignored) plus MONITORFAILCOUNT(failed) times before switching back to
the original connection state. The valid range is 0to 255. Any change will not become permanent until a SAVE
operation is performed.
SET MONITORMODE [FAILOVER/TOGGLE]
GET MONITORMODE
Set or display the Monitor Mode. In FAILOVER mode, the auto-switching function switches to the “failover”
connection state (all COMMON ports are connected to their respective A ports) when PING attempts fail, and if
configured to auto-recover, switches to the “normal” connection state (all COMMON ports are connected to their
respective B ports) when PING attempts succeed. In TOGGLE mode, the auto-switching function toggles the
connection state (A to B, or B to A) when PING attempts fail, and maintains the connection state when PING
attempts succeed. Any change will not become permanent until a SAVE operation is performed.
SET AUTHENTICATIONTRAP ON[OFF]
GET AUTHENTICATIONTRAP
Set or display the current state of authentication error traps. Authentication traps will be generated when this
parameter is set to ON, and not when OFF. Note that this setting only affects the trap generation, and not how the
Ethernet module handles an authentication failure. An authentication failure generally means that an SNMP access
was attempted with an incorrect community name. Any change will not become permanent until a SAVE and RESET
operation sequence is performed.
SET ALERTTYPE [TRAP/SYSLOG]
GET ALERTTYPE
Set or display the type of alert messages sent by the internal Ethernet module when certain events such as a change in
switch state occur. The Ethernet module can be configured to issue either syslog messages, or SNMP traps. Note
that at least one IP address must be entered using the “SET MANAGER N X.X.X.X” command before either syslog
messages or traps will be issued. See section 9 for a list of the traps supported by the Switching System, and see
section 10 for a list of the supported syslog messages.
SET ADMINIP N X.X.X.X
Set administrator N (1-8) IP address. Up to 8 different administrator IP addresses can be entered. To remove an
entry from the list, set the IP address to 0.0.0.0. If all 8 ADMIN IP addresses are 0.0.0.0 (no ADMIN IP addresses
are configured) the internal Ethernet module will allow access from any IP address, subject to the existing password
and enable flags for each interface. If one or more ADMIN IP addresses are non-zero, the internal Ethernet module
will only process messages received from the configured (non-zero) ADMIN IP addresses. All other messages will
be ignored. This ADMIN IP address filtering feature applies to the telnet, web browser and SNMP Ethernet
interfaces and to the PING reply functions. The ADMIN IP address filtering does not affect outgoing PING and
ARP messages so the Ethernet module is still able to monitor any IP address for the “auto-switch” features. The
administrator IP addresses can be different than the manager IP addresses. Any change will not become permanent
until a SAVE operation is performed.
