9T122-08 Module Specific Information

FNB Resource Configuration Codes

The 9T122-08 Token Ring MicroLAN Switch Extension Module provides connectivity between one of three interfaces: the front panel Token Ring interface(s) and the FDDI rings on the backplane (FNB-1 or FNB-2).

The FNB Resource ConÞguration Screen allows you to connect the moduleÕs front panel Token Ring interfaces 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.

ConÞguration	FDDI	Description
ID	Connections
		Neither the FNB-1 nor the FNB-2 on
1	NORING <-> TRNG	the chassisÕ backplane is connected to
		the moduleÕs bridge/switch.
		The FNB-1 on the chassisÕ backplane
2	FNB1 <-> TRNG	and the moduleÕs front panel Token
		Ring interfaces are connected to the
		same bridge/switch.
		The FNB-2 on the chassisÕ backplane
3	FNB2 <-> TRNG	and the moduleÕs front panel Token
		Ring interfaces are connected to the
		same bridge/switch.
