Appendix
9T122-24 Module Specific
Information
Introduction
This appendix contains local management information that is speciÞc to the
9T122-24 Token Ring MicroLAN Switch Module.
Physical RingTopology
When viewed from the front, the 9T122-24 Token Ring MicroLAN Switch
ModuleÕs token rotation is
up . The token moves from Port 12 to Port 11 to Port 10,
and so on. Therefore, Port 11 is downstream from Port 12 and upstream from Port
10.
Default Configuration
By default, the 9T122-24 Token Ring MicroLAN Switch Module is conÞgured for
24 ports on Token Ring 1.
If you want to conÞgure the module for 12 ports on Token Ring 1 and 12 ports on
Token Ring 2, you have to set a DIP switch on the module. For information about
setting DIP switches, see the
SmartSwitch 9000 9T122-24 Three Port Token Ring
MicroLAN Switch Module UserÕs Guide
.

Module Interfaces
The 9T122-24 Token Ring MicroLAN Switch Module has Þve interfaces. Table 1
lists the identifying number, name, and description of each interface.
FNB Resource Configuration Codes
The 9T122-24 Token Ring MicroLAN Switch Module provides connectivity
between either two or three interfaces: the front panel Token Ring interface(s) and
the FDDI rings on the backplane (FNB-1 or FNB-2).
The default operating conÞguration for the 9T122-24 module is a two port FDDI-
to-Token Ring bridge. All 24 front panel lobe ports are conÞgured as a single,
shared Token Ring segment, which is bridged to the FDDI-FNB backplane.
Optionally, you can segment the 24 ports into two smaller rings (or MicroLANs)
of 12 ports each (Ports 1-12 = Ring 1, Ports 13-24 = Ring 2) by repositioning, at
installation time, the on-board hardware DIP switch. These two MicroLANs are
then bridged together, in addition to the FDDI-FNB backplane, creating a three-
port bridge (two Token Rings and one FDDI interface bridged together).
The FNB Resource ConÞguration Screen allows you to connect the moduleÕs front
panel Token Ring interface to one of the chassisÕ two FDDI networks (FNB-1 or
FNB-2) via a bridge/switch.

The FNB Resource ConÞguration Screen lists all the possible connections that the
speciÞed module can support on the FNB, displays the current connection, and
allows you to change the connection. Table 2 lists and describes the FDDI
Connections from which you can select.

The FNB-1 on the chassisÕ backplane
and the moduleÕs front panel Token
Ring interface is connected to the
same bridge/switch.

The FNB-2 on the chassisÕ backplane
and the moduleÕs front panel Token
Ring interface is connected to the
same bridge/switch.

9T122-24 Module Specific Information
General Configuration Screen Fields
The following information brießy explains each General ConÞguration Screen
Þeld.
Module Serial #
Displays the serial number of the selected module.
Module Board Revision
Displays the version number of the selected module.
FLASH Memory
Displays the amount (megabytes) of ßash memory in the selected module.
Module Date
Contains a value that the module recognizes as the current date. To enter a new
date, highlight the Þeld and enter the date in MM/DD/YYYY format. The month
and day portion of the date must include two digits. Therefore, enter a leading
zero for months January through September, and for dates less than 10. For
example, for June 4, 1996, enter 06/04/1996 (slashes are optional). If you do not
enter slashes to separate the month, day, and year values, the Þrst eight digits you
enter in this Þeld represent an entry (i.e., 06041996).
ModuleTime
Contains a value that the module recognizes as the current time. To enter a new
time, highlight the Þeld and enter the time in HH:MM:SS format. Notice that
there is no AM/PM indicator. Time should be entered based upon a 24 hour clock.
For 4:07 p.m., enter 16:07:00 (colons are optional). If you do not enter colons to
separate the hours, minutes, and seconds values, the Þrst six digits you enter in
this Þeld represent an entry (i.e., 160700). For 6:12 a.m., enter 6:12:00 or 06120.
Screen RefreshTime
Contains the rate at which the moduleÕs screens are updated. This setting
determines how frequently (in seconds) information is updated on the screen. To
enter a new refresh rate, highlight the Þeld and enter a number. The
default
refresh rate is 3 seconds. The
range is 3 - 99 seconds.
The moduleÕs default date and time settings are indeterminate. The internal
calendar and clock begin running as soon as you install the module.

Screen LockoutTime
Contains the maximum number of minutes that the Local Management
application will display a moduleÕs screen while pending input or action from a
user. For example, if you enter 5 in this Þeld, users will have up to Þve minutes to
respond in some fashion to each of the speciÞed moduleÕs Local Management
screens. In our example, after Þve minutes of ÒidlenessÓ (no input or action), the
Local Management application terminates the session on the selected module and
the Slot Selection Screen reappears. To enter a new lockout time, highlight the
Þeld and enter a number. The
default lockout time is 15 minutes. The range is 1 -
30 minutes.
Host IP Address
Contains the Internet Protocol address currently assigned to the selected module.
Set this Þeld according to your network requirements. Highlight the Host IP
Address Þeld and enter the desired IP address using dotted decimal notation (4
decimal values between 1 and 255 separated by periods) as follows:
255.255.255.255
(255 is the maximum number that you can enter in any of the four segments.
Default = 0.0.0.0 .) This address can be used by any of the system interfaces on
the module.
Subnet Mask
Contains the subnet mask for the selected module. A subnet mask Òmasks outÓ
the network bits of the IP address by setting the bits in the mask to 1 when the
network treats the corresponding bits in the IP address as part of the network or
subnetwork address, or to 0 if the corresponding bit identiÞes the host. The
default subnet mask uses the Þrst two portions of the IP address to identify the
network id, leaving the rest of the IP address to identify speciÞc nodes. To enter a
new subnet mask, highlight the Þeld and enter a new value using dotted decimal
notation (4 decimal values between 1 and 255 separated by periods) as follows:
255.255.255.255
(The Subnet Mask Þeld defaults to the natural mask value, based on the IP
Address that you entered for the device.)
Default Gateway
Contains the IP Address of the device to which all packets addressed to an
unknown network or host are sent. If you do not conÞgure a Default Gateway,
any packets that are addressed to an unknown network or host will be dropped.
This Þeld is not deÞned until you enter an appropriate value using dotted
decimal notation (4 decimal values between 1 and 255 separated by periods).

9T122-24 Module Specific Information
Default Interface (Toggle)
Contains the number that represents the interface that is connected to the
moduleÕs Default Gateway. In some instances, dissimilar modules have different
corresponding interface numbers. For example, if you are assigning a default
interface to a 9T122-24 module and you enter a 3, then the default interface is the
Flexible Network Bus. However, if you are assigning a default interface to a
9F310-02 module and you enter a 3, then the default interface is the Internal
Network Bus. See Table 1 for module-speciÞc interface information. The
default
is NONE, meaning no default interface selected.
Base MAC Address
Displays the MAC Address of the selected module. This is the MAC Address of
the SMB-10 interface.
TFTP Gateway IP
The IP address of the router that connects to or is closest to the module. ConÞgure
this address when you are performing TFTP downloads in a routed environment
(if proxy ARP is disabled on the router).
The Default Interface Þeld becomes active after you enter an IP address in the
Default Gateway Þeld.
