Powering On the DC-Powered T1600 Router

You can use this procedure for a T1600 router for either three-input 240-A DC power supplies or four-input 240-A DC power supplies.

To power on the DC-powered 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 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 CIP (AUXILIARY, CONSOLE, or ETHERNET).

   Note: If you are powering on the router for the first time, the ETHERNET port does not function until after the initial configuration procedure.

4. Turn on the power to the external management device.
5. Switch on the dedicated customer site circuit breakers to provide power to the DC power cables. Follow your site’s procedures.
6. Verify that the INPUT PRESENT LED for each input on the DC power supply faceplate is lit steadily green, indicating that the inputs are receiving power.
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 circuit breakers on one of the power supplies to the ON position (|).

   Note: If the router 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 router again, see the procedure for powering off the router. After powering on a power supply, wait at least 60 seconds before turning it off.

9. Verify that the CB ON LEDs on the DC power supply faceplate are lit steadily, indicating that the circuit breakers are on.

   Note: 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 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. If any of the output status LEDs does not light steadily after 60 seconds, repeat the procedure to connect the DC cables. If you continue to have problems, see the replacement procedure for the power supply.

10. On the external management device connected to the Routing Engine, monitor the startup process to verify that the router has booted properly.
11. Verify that the DC OK LED on the DC power supply faceplate is lit steadily, indicating that power supply is correctly installed and functioning properly. The DC OK LED blinks momentarily, then lights steadily.
12. Repeat the procedure for the other power supply.
