Powering On a DC-Powered M10i Router

 

To power on a DC-powered 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 on a DC-powered router, verify that the source DC power cables are connected to the appropriate terminal on the power supply faceplate: the positive (+) source cable to the return terminal (labeled RTN) and the negative (–) source cable to the input terminal (labeled –48V).
  3. Verify that an external management device is connected to one of the Routing Engine ports on the Routing Engine (AUX/MODEM, CONSOLE, or MGMT).
  4. Turn on the DC power source so that voltage flows to the router.
  5. Turn on the power to the external management device.
  6. Press the power switch for the power supplies in slots P/S 0 and P/S 1 to the ON ( | ) position. The power switch is located on the power supply faceplate.

    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 router again, see Powering Off the M10i Router . After powering on a power supply, wait at least 60 seconds before turning it off.

    Note

    After a power supply is powered on, it can take up to 60 seconds for status indicators—such as LEDs on the power supply and command display output—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

  7. Press the power switch for any additional power supplies to the ON ( | ) position.
  8. Verify that the green OUTPUT OK LED on each power supply faceplate lights steadily.Note

    If the LED does not light after 60 seconds, verify that the power supply is properly inserted into the chassis and repeat the cable installation procedures described in Connecting Power on an DC-Powered M10i Router.

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