Module Specific Information

Introduction

This appendix contains local management information that is specific to the
9F120-08, 9F122-12 and 9F125-08 MicroLAN modules.

Default Interface Codes

The Default Interface field on the General Configuration Screen allows you to
enter a number (one through three). Each number represents a default interface
for the selected module. The table below lists the numbers you can enter, each
number’s corresponding interface, and a brief description of that interface. The
default for this field is NONE, meaning no default interface selected.

FNB Resource Configuration Codes

All of the MicroLAN Modules described in this appendix physically attach to the
FNB-1 and the FNB-2 on the SmartSwitch 9000 backplane. By default, the module
inserts into four rings (the primary and secondary rings of the FNB-1 and the
FNB-2). The FNB Resource Configuration Screen allows you to customize this
configuration to your particular needs.

The FNB Resource Configuration Screen allows you to:

• Select the rings (primary or secondary) of each FNB to which the module will
attach

• Determine whether the module will insert into those rings or bypass them

• Select the ring where the MAC will reside

The terms INSERT and BYPASS refer to relays that are located on the module.
INSERT causes a relay to connect the module’s front panel ports to the selected
ring. BYPASS causes a relay to disconnect the module’s front panel ports from the
selected ring.

BYPASS:

The FNB Resource Configuration Screen lists all possible connections a 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.
