    Connecting AC Power to the M40e Router

    To connect AC power to the router:

    1. Verify that the power supplies are fully inserted in the chassis and the thumbscrews on their faceplates are tightened.
    2. For each power supply, verify that the ends of the power cord are firmly plugged into the appliance inlet on the power supply faceplate and the external power source receptacle.

      Note: The AC power source must supply 220 VAC power (nominal range 200–240 VAC), not 110 VAC power (nominal range 100–120 VAC).

    3. Connect a management device to one of the ports on the Connector Interface Panel (CIP) (AUXILIARY, CONSOLE, or ETHERNET) for the Routing Engine that is configured to become the master. For more information on connecting management devices, see Replacing Connections to the M40e Routing Engine Interface Ports.
    4. Turn on the management device.
    5. Press the power switch on the faceplate of one power supply to the ON ( | ) position. Verify that the green OUTPUT OK LED eventually lights steadily.

      Note: After powering off a power supply, wait at least 60 seconds before turning it back on. After powering on a power supply, wait at least 60 seconds before turning it off.

      If the system is completely powered off when you power on the power supply, the Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power off the system again, see Disconnecting AC Power from the M40e Router or Disconnecting DC Power from the M40e Router.

      After a power supply is powered on, it can take up to 60 seconds for status indicators—such as LEDs on the power supply, show chassis commands, and messages on the craft interface LCD—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

    6. Press the power switch on the other power supply to the ON ( | ) position and observe the LEDs on the power supply faceplate. They should light as described in the previous step.

      If the LEDs are not lit in the appropriate pattern after 60 seconds, repeat the procedures in Installing an M40e AC Power Supply and the previous steps in this procedure.

      Note: When two power supplies are installed, at least one Routing Engine and one FPC must also be installed for both power supplies to power on. In the absence of this minimum load, only one power supply starts. (The router powers on and operates correctly with one power supply, but without the redundancy benefit of a second power supply.)

    7. On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.
