Step 2: Check the Craft Interface Environmental Status

Action

To check the craft interface status, use the following CLI command:

user@host> show chassis environment

Sample Output

For M5, M10, M20, and M40 routers:

user@host> show chassis environment

Class Item                   Status     Measurement

[...Output truncated...]

Misc  Craft Interface        OK        

For M40e and M160 routers:

user@host> show chassis environment

Class Item                   Status     Measurement

[...Output truncated...]

      FPM CMB                OK         32 degrees C / 89 degrees F

      FPM Display            OK         32 degrees C / 89 degrees F

[...Output truncated...]

For M40e and M160 routers:

user@host> show chassis environment

Class Item                   Status     Measurement

[...Output truncated...]

      FPM GBUS               OK         28 degrees C / 82 degrees F

      FPM Display            OK         31 degrees C / 87 degrees F

[...Output truncated...]

What It Means

For M5, M10, M20, and M40 routers, the command output displays the craft interface state, which can be OK or Absent.

For M40e and M160 routers, the command output displays the FPM Chassis Management Bus (CMB) status and the FPM display status, which can be OK or Absent.

For M320 routers, the command output displays the FPM CMB status only.

For T320 routers and T640 routing nodes, the command output displays the FPM circuitry and the FPM display status, which can be OK or Absent.

Alternative Action

(For M40e, M160, M320, and T320 routers and the T640 routing node) To monitor the craft interface environmental status, use the following CLI command:

user@host> show chassis environment fpm

user@host> show chassis environment fpm

FPM status:

  State                       Online

  FPM CMB Voltage:

    5.0 V bias           5030 mV

    8.0 V bias           8083 mV

  FPM Display Voltage:

    5.0 V bias           4998 mV

  FPM CMB temperature      34 degrees C / 93 degrees F

  FPM Display temperature  35 degrees C / 95 degrees F

  CMB Revision             12

The command output displays the status of the FPM or craft interface, which can be Online or Offline. It also displays information about the power supplied to the FPM CMB or FPM GBUS, information about the FPM display power supply, the temperature of the air flowing past the FPM CMB or FPM GBUS and the FPM display, and the CMB or GBUS revision level.
