Maintaining FPCsThe router can have up toeight 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,p erformthe following procedures regularly:
Check the LCD on the craft interfaceand the LEDs on the craft interface
directly aboveeach FPC slot. The green LED labeled OK lights steadily when
an FPC is functioning normally. Formore information, see “FPC LEDs and
Offline Button” on page 31.
Issue the CLI showchassis fpc command to ch eck the status of installed FPCs.
Asshowninthesampleoutput,thevalueOnline in the column labeled State
indicates that the FPC is functioningnormally:
