Powering On the TX Matrix Router

 

To power on the router:

  1. Verify that the power supply is 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 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 TX-CIP (AUXILIARY, CONSOLE, or ETHERNET).
  4. Verify that the M/S and CHASSIS ID switches on the faceplate of each Control Board are set to S and 0.
  5. Turn on the power to the external management device.
  6. Switch on the customer site circuit breakers to provide voltage to the DC power source cables.
  7. For a three-input 240-A power supply in two-input mode, verify that the INPUT PRESENT LEDs on the power supply faceplate are lit steadily, indicating that the inputs are receiving power.
  8. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
  9. Switch the circuit breakers on one of the power supplies to the on position (|).Note

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

  10. Verify that the CB ON LEDs on the power supply faceplate are lit steadily. The CB ON LEDs blink momentarily, then light steadily to indicate that the circuit breakers are on.
  11. Verify that the DC OK LED on the power supply faceplate is lit steadily, indicating that the power supply is correctly installed and is functioning properly.Note

    If any of the output status LEDs do not light steadily, repeat the cabling procedures described in Connecting Power to a Three-Input 240-A Power Supply In 2-INPUT Mode in a TX Matrix Router or Connecting Power to a Two-Input 160-A Power Supply in a TX Matrix Router.

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

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, see Powering Off the TX Matrix Router.
