Powering On an AC-Powered Router

To power on the router:

1. Verify that the power supplies are fully inserted in the chassis and the thumbscrews on their faceplates are tightened.
2. Verify that the ends of each power cord are firmly plugged into the appliance inlet on the power supply faceplate and the external power source receptacle.
3. Verify that an external management device is connected to one of the Routing Engine ports (AUX/MODEM, CONSOLE, or MGMT). For more information about connecting management devices, see Connecting the Router to Management and Alarm Devices.
4. Turn on the power to the external management device.
5. Press the power switch on the faceplate of the power supplies in slots P/S 0 and P/S 1 to the ON ( | ) position.

   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 show chassis commands—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.

   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 to an AC-Powered Router.

6. Verify that the OUTPUT OK LED on each power supply faceplate eventually lights steadily.
7. Press the power switch for any additional power supplies to the ON ( | ) position and verify that the OUTPUT OK LED on each power supply faceplate lights steadily.
8. On the external management device connected to the Routing Engine, monitor the startup process to verify that the system has booted properly.

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

Note: After powering off a power supply, wait at least 60 seconds before turning it back on. 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, first issue the CLI request system halt command. For more information, see Disconnecting AC Power from the Router.
