Step 1: Check the Redundant MCS Environmental Status

Action

To check the redundant MCS status, use the following CLI command:

user@host> show chassis environment mcs

Sample Output

user@host> show chassis environment mcs

MCS 0 status:

  State                           Online Master

  Temperature                   0 degrees C / 32 degrees F

  Power:

    3.3 V                    3318 mV

    5.0 V                    5001 mV

    12.0 V                  11833 mV

    5.0 V bias               4991 mV

    8.0 V bias               8341 mV

  CMB Revision                 12

  FPGA Revision                12

MCS 1 status:

  State                           Present

  Power:

    3.3 V                    3308 mV

    5.0 V                    5013 mV

    12.0 V                  11809 mV

    5.0 V bias               4952 mV

    8.0 V bias               8346 mV

  CMB Revision                 12 

What It Means

The show chassis environment mcs CLI command is available on the M40e and M160 routers only. The command output displays environmental information about both MCSs installed in the router or about an individual MCS. The MCS status can be Present, Online, Offline, or Empty. The command also indicates that the MCS is the master MCS. The command output also displays the temperature of the air flowing past the MCS, information about MCS power supplies, field-programmable gate array (FPGA) revision information, and the revision level of the chassis management bus (CMB) slave.

Alternative Action

To display the environmental status of a particular MCS, use the following JUNOS CLI operational mode command:

user@host> show chassis environment mcs slot
