Step 4: Check the FPC LED States

Action

To check the FPC LED status, use the following CLI command:

user@host> show chassis craft-interface

Sample Output

user@host> show chassis craft-interface

Front Panel FPC LEDs:

FPC    0   1   2   3   4   5   6   7

------------------------------------

Red    .   .   .   .   .   .   .   .

Green  *   *   .   .   .   .   .   .

What It Means

The Front Panel FPC LEDs section displays the status of each FPC. The FPCs have two operational states: Green (OK), and Red (Fail). Asterisks (*) indicate the operating state. Dots indicate an off state for LEDs. If both red and green LEDs have dots, the FPC slot is empty. Asterisks in the Green state indicate that the FPCs in slots 0 and 1 are operating normally. No FPCs are installed in slots 2 through 7.

Alternative Action

(For all routers except the M5, M7i, M10, and M10i) You can also check the FPC status by looking at the LEDs on the faceplate. Each FPC has two LEDs that report its status. Only one LED state can occur at a time. Table 46 describes the FPC LEDs.

Table 46: FPC LEDs on the Faceplate

Label	Shape	Color	State	Description
OK		Green	On steadily	FPC is functioning normally.
			Blinking	FPC is starting up.
FAIL		Red	On steadily	FPC has failed.

(For all routers except the M5, M7i, M10, and M10i, you can check the FPC status by looking at the FPC LEDs on the craft interface. Table 47 describes the functions of the FPC LEDs.

Label	Color	State	Description
FAIL	Red	On steadily	FPC has failed.
OK	Green	On steadily	FPC is functioning normally.
		Blinking	FPC is starting up.
