Monitor the HCM Status
To monitor the HCM status:
Check HCM LEDs
Purpose
To monitor the HCM status by checking the HCM LEDs on the component faceplate.
Action
To check the HCM LEDs, look at the component faceplate at the bottom left front of the M10i router chassis (see Table 1).
Two LEDs indicate HCM status—a green PWR LED and a blue MSTR LED. describes the LED states.
Table 1: HCM LEDs
Label | Color | State | Description |
|---|---|---|---|
PWR | Green | On steadily | HCM is functioning normally |
Blinking | HCM is starting up. | ||
MSTR | Blue | On steadily | HCM is master. |
Check HCM Environmental Status
Purpose
To isolate problems in the HCM by checking the environmental status.
Action
To check the HCM environmental status, use the following command:
Sample Output
user@host> show chassis environment hcmHCM 0 status: State Online Master FPGA Revision 27 HCM 1 status: State Present Standby FPGA Revision 27
Meaning
The command output shows that the HCM status, including slot number, operating state, and field programmable gate array (FPGA) revision.
To display the environmental status of a particular HCM, use the following command:
m10i@host> show chassis environment hcm slotCheck the Companion Routing Engine Status
Purpose
The HCM in the slot labeled HCM0 is paired with the Routing Engine in the slot labeled RE0. Likewise, the HCM in the slot labeled HCM1 is paired with the Routing Engine in the slot labeled RE1. By default, the HCM in the slot labeled HCM0 is the master.
When HCM mastership changes because of failure, Routing Engine mastership changes as well.
Action
To check Routing Engine status, use the following command:

The command output displays the operating state of both Routing Engines installed in the router chassis, including slot number, current state, and default election priority—master or backup. The command output also displays the Routing Engine temperature, amount of memory, and the percentage of memory and CPU utilization. The command output displays the Routing Engine model number, serial number ID, start time, and total operating time.
Look at the Routing Engine LEDs by using the show chassis routing-engine command or by looking at the component faceplate at the front of the router. The Routing Engine has four LEDs that tell operating status: a green LED labeled HDD, a blue LED labeled MASTER, a red LED labeled FAIL, and a green LED labeled ONLINE. Table 2 describes the Routing Engine LED states.
Table 2: Routing Engine LEDs
Label | Color | State | Description |
|---|---|---|---|
HDD | Green | Blinking | There is read/write activity on the PC card. |
MASTER | Blue | On steadily | Routing Engine is functioning as master. |
FAIL | Red | On steadily | Routing Engine is not operational. |
ONLINE | Green | On steadily | Routing Engine is running normally. |
