Step 2: Check the HCM Environmental Status

Action

To check the HCM environmental status and view which HCM is functioning as master, use the following CLI command:

user@host> show chassis environment hcm

Sample Output

user@host> show chassis environment hcm

HCM 0 status:

  State                           Online Master

  FPGA Revision                27

HCM 1 status:

  State                           Online Standby

  FPGA Revision                27

What it Means

The command output shows that both HCMs (HCM0 and HCM1) are online. HCM0 is functioning as master, and HCM1 is functioning as standby. The command output also gives the Field Programmable Gate Array (FPGA) revision level. The FPGA is a gate on the chip used in the HCM.

Alternative Action

To display the status of an HCM in a certain slot, use the following CLI command:

user@host> show chassis environment hcm 1

Sample Output

user@host> show chassis environment hcm 1

HCM 1 status:

  State                           Online Standby

  FPGA Revision                27
