Step 1: Check the MCS Environmental Status

Action

To check the MCS environmental status, use the following JUNOS software command-line interface (CLI) command:

user@host> show chassis environment mcs

Sample Output

user@host> show chassis environment mcs

MCS 0 status:

  State                           Online Master

  Temperature                  43 degrees C / 109 degrees F

  Power:

    3.3 V                    3318 mV

    5.0 V                    4974 mV

    12.0 V on                 12

  FPGA Revision                13

MCS 1 status:

  State                           Online Standby

  Temperature                  58 degrees C / 136 degrees F

  Power:

    3.3 V                    3317 mV

    5.0 V                    5006 mV

    12.0 V                  11843 mV

    5.0 V bias               4998 mV

    8.0 V bias               8195 mV

  BUS Revision                 12

  FPGA Revision               255

What It Means

The show chassis environment mcs 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
