Step 4: Display the SFM Environmental Status

Action

To display the SFM environmental information, use the following CLI command:

user@host> show chassis environment

Sample Output

user@host> show chassis environment

What it Means

The command output displays the status and temperature for the SFM and its two serialized components: the SPP card and the SPR card.

Alternative Action

If there is a problem with the SFM status, you can display more detailed environmental information with the following CLI command:

user@host> show chassis environment sfm 

user@host> show chassis environment sfm

SFM 0 status:

  State                           Online

  SPP temperature              36 degrees C / 96 degrees F

  SPR temperature              45 degrees C / 113 degrees F

  SPP Power:

    1.5 V                    1501 mV

    2.5 V                    2485 mV

    3.3 V                    3291 mV

    5.0 V                    5020 mV

    5.0 V bias               4974 mV

  SPR Power:

The command output displays the SFM slot, status, and temperature of the air flowing past the SPP card and the SPR card. It also displays information about the SFM power supplies. The chassis management bus (CMB) slave revision level is also displayed.

You can display the environmental status of a particular SFM with the following CLI command:

user@host> show chassis environment sfm sfm-lot
