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:
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 4 Empty 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:
