    Maintaining the MX2020 Power Supply Modules

    Purpose

    For optimum router performance, verify the condition of the PSMs.

    Action

    On a regular basis:

    • Check the status of the PSMs by issuing the show chassis environment psm command.

      The output displays the chassis AC PSM status:

    • Make sure that the power and grounding cables are arranged so that they do not obstruct access to other router components.
    • Routinely check the status LEDs on the AC or DC PSM faceplates and the craft interface to determine if the PSMs are functioning normally.
    • Check the red and yellow alarm LEDs on the craft interface. PSM failure or removal triggers an alarm that causes one or both of the LEDs to light. You can display the associated error messages by issuing the following command:
      user@host> show chassis alarms
    • Periodically inspect the site to ensure that the grounding and power cables connected to the router are securely in place and that there is no moisture accumulating near the router.
