Check the Component LEDs

Action

To check the component LED status, do one of the following:

• Use the following CLI command:

user@host> show chassis craft-interface

The command output displays the LED status for the following components:

• M7i/M10i/M20 router: Routing Engine and FPC
• M40e/M160 router: Routing Engine, FPC, MCS, PCG, and SFM
• M320 router: Routing Engine, FPC, Control Board, SIB, and power supply (PS)
• T320 router and T640 routing node: Routing Engine, FPC, Control Board, SCG, and SIB

• Physically look at the craft interface. You see the following component LEDs:

• M5/M10, M20, and M40 routers: Routing Engine
• M40e/M160 routers: host module
• T320 router and T640 routing node: host subsystem, FPCs, PICs, and SIBs

• Look at the LEDs on the component faceplate. Table 17 describes where the LEDs are located on the router.

Table 17: Component LED Location on the Router

Component	LED Location on the Router
Routing Engine	(M5/M10, M40e, and M160 routers) Remove the component cover. (M7i/M10i routers) On the Routing Engine faceplate at the front of the router. (M20 router) On the rear Routing Engine panel. (M20, M40, M40e, M160, and M320 routers) On the craft interface. The M40e and M160 router Routing Engine is paired with an MCS and is monitored by the host module LEDs on the craft interface. The M320 router, T320 router, and the T640 routing node Routing Engine is paired with a Control Board and is monitored by the host subsystem LEDs on the craft interface Remove the cover for the Routing Engine on the M40e, M160, and T320 routers and the T640 routing node. Note: You cannot see the Routing Engine LED on the M40 router.
FPC	(M20, M40, M40e, M160, and M320 routers) On the FPC faceplate at the front of the router. (M320 router) On the craft interface
PIC	(M5 and M10 routers) On the craft interface. (M7i router) On the PIC faceplate at the front of the router. (M10i router) On the FIC faceplate at the front of the router and on the PIC faceplate at front of the router. (All other routers) On the PIC faceplate at the front of the router.
Power supply	On the power supply faceplate at the bottom rear of the router. (M320 router) On the craft interface.
Host module	(M40e and M160 routers) On the craft interface. Remove the component cover.
SFM	(M40e and M160 routers) On the SFM faceplate at the rear of the router. Remove the component cover.
MCS	(M40e and M160 routers) On the MCS faceplate at the rear of the router. Remove the component cover.
PCG	(M40e and M160 routers) On the PCG faceplate at the rear of the router. Remove the component cover.
SCB	(M40 router) On the SCB faceplate at the front of the router, vertical in the middle of the FPC card cage.
SSB	(M20 router) On the SSB faceplate at the top front of the router.
Control Board	(T320 router and T640 routing node) On the Control Board faceplate at the upper rear of the chassis.
SCG	(T320 router and T640 routing node) On the SCG faceplate at the upper rear of the chassis.
SIB	(M320, T320 router and T640 routing node) On the SIB faceplate at the center rear of the chassis. (M320 router) On the craft interface.
CFEB	(M7i/M10i routers) On the DFEB faceplate at the rear of the router.
FIC	(M7i router) On the FIC faceplate at front of the router.
HCM	(M10i router) On the HCM faceplate at front of the router.
