What it Means

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

Alternative Actions

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

The command output displays the SFM slot, status, and the temperature of the air flowing past the SPP and SPR cards. 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 slot
