Maintaining FPCs

The router can have up to eight Flexible PIC Concentrators (FPCs) mounted vertically in the FPC card cage at the front of the chassis, as shown in Figure 1. To maintain FPCs, perform the following procedures regularly:

Check the LCD on the craft interface and the LEDs on the craft interface directly above each FPC slot. The green LED labeled OK lights steadily when an FPC is functioning normally. For more information, see “FPC LEDs and Offline Button” on page 31.

Issue the CLI show chassis fpc command to check the status of installed FPCs. As shown in the sample output, the value Online in the column labeled State indicates that the FPC is functioning normally:

user@host> show chassis fpc
		Temp	CPU Utilization	(%)	Memory	Utilization (%)
Slot	State	(C)	Total Interrupt		DRAM (MB) Heap		Buffer
0	Online	37	4	0	32	1	39
1	Online	39	4	0	32	1	39
2	Empty
3	Online	34	1	0	32	1	40

5	Online	35	4	0	32	2	40
6	Online	36	4	0	32	1	39
7	Empty

For more detailed output, add the detail option. The following example also specifies a slot number (0), which is optional:
