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.
INSERT:
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.
