    Powering On the AC-Powered MX2020 Router

    You can use this procedure for a router with either a three-phase delta AC PDM or a three-phase wye AC PDM. To power on the AC-powered router:

    1. Verify that the PSMs are fully inserted in the chassis and that the captive screws on their faceplates are tightened.
    2. Verify that each AC power cord is connected correctly.
    3. Verify that an external management device is connected to one of the Routing Engine ports on the CB-RE (AUX, CONSOLE, or MGMT).

      Note: The management Ethernet port will not be functional until you have completed the initial configuration.

    4. Turn on the power to the external management device.
    5. Switch on the dedicated customer site circuit breakers to provide power to the AC power cables. Follow your site’s procedures.
    6. Verify that the LEDs on both PDM and PSM light green steadily.

      If any of the status LEDs indicates that the PDM is not functioning normally, repeat the installation and cabling procedures.

    7. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    8. Switch the power switch on one of the PSMs to the on (|) position. The OK led blinks momentarily, then lights steadily.

      Note: After a PSM and PDM are powered on, it can take up to 60 seconds for status indicators—such as the output status LEDs on the PSM, and the command output on the craft interface—to indicate that the PSM and PDM are functioning normally. Ignore error indicators that appear during the first 60 seconds.

    9. Verify that the PWR OK LED on the AC PSM faceplate is lit steadily, indicating that PDM is correctly installed, functioning properly, and providing power to the AC outputs.
    10. On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.
    11. Verify the MX2020 router power up, system initialization, and status. See Initially Configuring the MX2020 Router, and Maintaining and Verifying the Status of the MX2020 Router Components.
