Using FPC Numbers in Routing Matrix CLI Commands

A standalone T640 routing node can be configured with up to eight FPCs (numbered 0 through 7). Since a routing matrix can have up to four T640 routing nodes, and each T640 routing node has up to eight FPCs, the routing matrix can have up to 32 FPCs (0 through 31).

Table 6 shows the correspondence between the FPC hardware slot numbers in the T640 routing nodes and the FPC assignments recognized by the JUNOS software for a routing matrix.

Table 6: FPC Correspondence Between T640 Routing Nodes and the Routing Matrix

T640 Routing Node	T640 FPC Range	Routing Matrix FPC Range
LCC 0	0-7	0-7
LCC 1	0-7	8-15
LCC 2	0-7	16-23
LCC 3	0-7	24-31

Using FPC Numbers in Operational Mode Chassis Commands

You can specify the FPC slot number in operational mode chassis commands in two ways:

• Specify the number of the T640 routing node using the lcc number option and use a value from 0 through 7 for the FPC slot number.

This is the recommended method. The show command output also lists information in this way, sorted first by LCC number and then by FPC slot 0 through 7.

• Omit the lcc number option and use a value from 0 through 31 for the FPC slot number.

For example, the following commands have the same result, but the first is the recommended usage:

user@host> request chassis fpc lcc 1 slot 1 offline
user@host> request chassis fpc slot 9 offline
