Maintain FPCs and PICs
The router can have up to eight Flexible PIC Concentrators (FPCs) mounted vertically in the
FPC card cage at the front of the chassis (see Figure 1). To maintain FPCs and the Physical
Interface Cards (PICs) housed in them, perform the following procedures on a regular basis:
FPC card cage at the front of the chassis (see Figure 1). To maintain FPCs and the Physical
Interface Cards (PICs) housed in them, perform the following procedures on a regular basis:
Check the LCD on the craft interface and the LEDs on the craft interface directly below
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 18.
Check the LEDs on PIC faceplates. Most PIC faceplates have an LED labeled
STATUS
.
Some PICs have additional LEDs, often one per port. The meaning of the LED states
differs for various PICs. For more information, see the M20 and M40 Internet Routers PIC
Guide. If the FPC that houses the PIC detects a PIC failure, the FPC informs the SCB,
which in turn sends an alarm to the Routing Engine.

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:

To check the status of a PIC, issue the CLI
show chassis fpc pic-status
command. The
following example specifies an FPC slot number (

), which is optional. The PIC slots in
an FPC are numbered from
