Troubleshoot PICs
To troubleshoot PICs, follow these guidelines:
To check the status of each port on a PIC, look at the LED located on the PIC faceplate.
For information about the meaning of LED states on different PICs, see the M20 and M40
Internet Routers PIC Guide.
Internet Routers PIC Guide.
To check the status of a PIC, issue the following CLI command. The following example
specifies an FPC slot number (
3
), which is optional. The PIC slots in the FPC are
numbered from
0
(zero) through
3
, top to bottom:
user@host> show chassis fpc pic–status 3
Slot 3 Online
PIC 0 4x OC-3 SONET, MM
PIC 1 4x OC-3 SONET, SMIR
PIC 2 1x OC-12 SONET, SMIR
PIC 3 1x G/E, 1000 BASE-SX
Troubleshoot the SCB
To troubleshoot the SCB, follow these guidelines:
Periodically check the alarm LEDs and the LCD on the craft interface. If the SCB is not
functioning properly, it might send spurious error messages to the Routing Engine
(indicating incorrectly that system components are malfunctioning, for example). These
messages can appear on the LCD.
(indicating incorrectly that system components are malfunctioning, for example). These
messages can appear on the LCD.
If all four LEDs on the SCB faceplate are on, but dimly lit, the SCB is probably not seated
properly. Tighten the captive screws at the top and bottom of the SCB card carrier. For
more information about the LEDs, see “SCB Components” on page 13.
