Maintaining the MX2010 Routing Engines

Purpose

Each host subsystem comprises a Control Board and Routing Engine (CB-RE) functioning together.

To maintain the host subsystem, check the LEDs (RE0 and RE1) on the craft interface. For more information about the LEDs and the display, see MX2010 Craft Interface Description .

Note:

Even though the Routing Engine is combined with a Control Board (CB-RE), separate LEDs on the craft interface show the status of the Routing Engines, and separate LEDs show the status of the Control Boards.

For optimum router performance, verify the condition of the Routing Engines and the Control Boards.

Action

On a regular basis:

  • Check the host subsystem LEDs on the craft interface. For more information about the LEDs, and the display, see MX2010 Craft Interface Description . During normal operations:

    Note:

    Even though the Routing Engine is combined with a Control Board (CB-RE), separate LEDs on the craft interface show the status of the Routing Engines, and separate LEDs show the status of the Control Boards.

    • The green host subsystem ONLINE LED on the craft interface is lit.

    • The red host subsystem OFFLINE LED on the craft interface is not lit.

  • Check the LEDs on the Routing Engine portion of the CB-RE faceplate. During normal operations, the ONLINE LED is lit steadily green.

  • Issue the show chassis routing-engine command to check the status of the Routing Engines. The output is similar to the following:
