Ports

10
For 10/100 Base-TX ports, plug a Category 5 (or better) twisted pair cable
into one of the RJ45 copper ports (1-6). Connect the other end to the far
end station. Verify that the Port LED’s are ON once the connection has
been completed. For Switch to Switch or Switch to Repeater connections, a
crossover cable may be required if the connecting unit does not support the
HP-MDIX auto cable detect feature. For 10/100BaseTX operation, the
608MFX will sense & adapt accordingly.
A maximum number of 50 608MFX’s can be connected in a ring.
CONNECTING MULTIPLE RINGS
For multiple rings, the connection between two network segments is made
on two separate paths. Two of the 608MFX’s in a ring are connected
together via a connection cable with an ITP cable (maximum length of
40m), and inform each other of their operating states. One of the 608MFX
units is assigned the redundant function using the DIP switch setting “Stby
on” (Standby Slave). The other 608MFX unit takes over the function of the
Standby Master, with the DIP switch setting “Stby off” (See Figure 2).
Because of the 50-unit ring limit, for larger networks, the user must
configure multiple rings. By using the Master/Slave Standby approach to
couple rings together, the user can enlarge the network by chaining
segments.
Port Assignment in the Standby Mode
On the Standby Master and Standby Slave only port #1 (default standby
port) can be used for the coupling to the neighboring ring. Connect the #1
ports together using a CAT5E crossover cable between switches. Ports 2-6
can be used just as normal switch ports.
Simultaneous Standby and Redundancy Manager Operation
A standby master or standby slave can adopt the function of a redundancy
manager at the same time.

11
Replacing the Standby Master during operation
When replacing a standby master during operation, the following procedure
is necessary to prevent an interruption on the network.
1. Remove the terminal block for power supply to the standby master.
2. Remove the signal lines and the standby connecting cable from the
standby master.
3. Connect the signal lines to the replacement device.
4. Plug the power terminal block into the replacement device.
When replacing the standby slave, no special steps are necessary.

DISPLAYS AND OPERATOR CONTROLS
LED’s
Fault (red LED)
Status Meaning
ON The 608MFX has detected an error. The signaling contact
opens at the same time.
OFF No errors detected by the 608MFX.
Stby -Standby (green LED)
Status Meaning
ON The 608MFX standby function is activated, indicating the
608MFX is in the standby passive mode.
OFF The standby function is deactivated.
Flashing The 608MFX standby function is activated, indicating the
608MFX is in the active mode. In other words, the Ring
master has failed and the standby takes over the data
traffic.
RM – Redundancy Manager (green LED)
Status Meaning
ON The 608MFX is operating in the redundancy manager
mode. The ring is operating free of errors, as monitored
by the redundancy manager.
Note: One (and only one) 608MFX must operate as the
redundancy manager in each ring.
OFF The 608MFX is not operating in the redundancy manager
mode.
Flashing The redundancy manager has detected a break in the ring.
The 608MFX makes the connection between its two ring
ports so that a functional bus configuration is re-
established within 300 ms.

13
Port LED’s
The Display Mode is indicated by the LED pair labeled “Display Mode”, and the
state is given by the legend on the front of the 608MFX. To transition between
these Display Modes, the Select/Set button must be pressed briefly (similar to left
mouse click). The four states are: Port Status, 100Mbit/s, Full Duplex, Fault Mask.
Display Mode:
State = Port Status Meaning
OFF No Valid Connection to the port.
Green Valid Connection to the port (good link).
Flashes green once per cycle, port switched to
standby
Flashes green three times per cycle, port is disabled
by configuration.
Yellow Indicates Port is actively receiving data
Display Mode:
State = 100 Mbps Meaning
OFF Port operating at 10 Mbps
Green Port operating at 100 Mbps
Display Mode:
State = Full Duplex Meaning
OFF Port operating half duplex
Green Port operating full duplex
Display Mode:
State = Fault Mask Meaning
OFF Port is not currently monitored
Green Port is currently monitored

14
“Select/Set” Button
The "Select/Set" multi-functional button on the front panel of the 608MFX
performs the following actions:
•Pressing the button briefly (similar to left mouse click) transitions the
display of the two display mode LED’s. The current display mode is
indicated by the status of the display mode LED’s per the legend
definition on the front of the 608MFX.
•If the Display Mode is currently selecting port status (all Display Mode
LEDs off) and if the button is pressed for three seconds, the Display
Mode LEDs begin to flash. If you then continue to press the button for
a further two seconds, the 608MFX is reset. When the 608MFX is
reset, all the settings return to their defaults (as set in the factory). This
allows you to cancel settings made from the Web based management
tools, Telnet, or the command line configurator (serial port), or the fault
mask.
•If the Display Mode is currently selecting the fault status and you press
the button for two seconds, the display LEDs start to flash. If you then
continue pressing the button for another two seconds, the current status
of the ports and the supply voltage are entered in the fault mask. Any
change in their status after the fault mask update will create a fault.
Note: Do not press the “Select/Set” button while the unit is powering up. In the
event that the "Select/Set" button was pressed while the 608MFX is starting up
(approximately a 20-second window), all display mode LEDs will flash
simultaneously. This mode is exited by pressing the button again after the unit
has completely powered up (a 20-second delay).

15
Aging Time
A 608MFX monitors the age of the addresses it has learnt, and addresses that
exceed a certain age (aging time, default setting = 40 sec), are deleted again by
the 608MFX. If a packet with a source address matching the address entry is
received before the aging time elapses, the address entry is retained, and the age
is reset. If a packet is received and there is no address entry for the source
address, it is learnt. If a packet is received and there is no address entry for the
destination address, it is sent to all ports.
IEEE 802.1Q, VLAN
The 608MFX does not support VLAN tags according to IEEE 802.1Q. Users
must configure their networks so that no VLAN packets are sent to the
608MFX.
IEEE 802.1P, QOS
The 608MFX does support QOS. Users should configure their networks such
that no packets with a priority tag higher than 3 are transmitted via the 608MFX
since these packets can influence redundancy functions (for example, longer
switchover times if a fault develops, or false fault detection).
Two-Pin Dip Switch Setting
With the two-pin DIP switch on the upper casing of the 608MFX, you can
do the following:
•With the Stby button, you can activate the standby function of the
device.
•With the RM switch, you can activate the redundancy manager
function of the device.
Note: The 6089MFX must be restarted after changing the DIP switch
settings. The switch settings are only adopted when the device powers up.

16
Serial Interface
The 608MFX provides an EIA-232 interface accessed via a 9 pin male
connector (labeled V24 on the unit). This is used to access the Command Line
Interpreter (CLI). Functions include setting the IP address, and other parameters
(see Network Management users guide). The pinouts are shown below:
