Powering On the T320 Router

 

To power on the router:

  1. Verify that the power supplies are fully inserted in the chassis and that the captive screws on their faceplates are tightened.
  2. Verify that the source power cables are connected to the appropriate terminal: the positive (+) source cable to the return terminal (labeled RETURN) 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 CIP (AUXILIARY, CONSOLE, or ETHERNET). For more information about connecting management devices, see Overview of Connecting the T320 Router to External Devices.
  4. Turn on the power to the external management device.
  5. Switch the circuit breaker on one of the power supplies to the on position (|) and observe the LEDs on the power supply faceplate. If the power supply is correctly installed and is functioning properly, the DC OK LED lights steadily, and the CB ON LED blinks momentarily, then 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 Powering Off the T320 Router.

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

  6. Repeat Step 5 for the remaining power supply.Note

    If any of the output status LEDs does not light steadily, repeat the installation and cabling procedures described in Replacing a T320 DC Power Supply and Connecting DC Power to the T320 Router.

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