FNB Resource Conﬁguration Codes

9F120-08 / 9F122-12 / 9F125-08 Module Speciﬁc Information

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.

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.
