Connect AC Power to the Router
- Verify that the power supplies are fully inserted in the chassis, that the thumbscrews and extractor/inserters on their faceplates are tightened, and that the power switches on both faceplates are in the
OFF(0) position. - For both power supplies, verify that the ends of the power cord are firmly plugged into the appliance inlet on the power supply faceplate and the external power source receptacle.
- Turn on the power to the management device that is connected to the Routing Engine through the craft interface port labeled
CONSOLE,AUXILIARY, orMANAGEMENT ETHERNET. For more information on connecting management devices, see Connect the Router to Management and Alarm Devices. - Press the power switch on the faceplate of one power supply to the
ON(|) position. The greenOKLED on the power supply faceplate blinks rapidly for a short time, then lights steadily.
After a power supply is turned on, it can take up to 60 seconds for status indicators—such as LEDs on the power supply,
show chassiscommands, and messages on the craft interface LCD—to indicate that the power supply is functioning normally. Ignore error indicators that appear during the first 60 seconds.The Routing Engine boots as the power supply completes its startup sequence. If the Routing Engine finishes booting and you need to power down the router again, first issue the CLI
request system haltcommand. For complete instructions, see Disconnect AC Power from the Router.If after powering on the power supply you must power it off, wait at least 60 seconds. After powering off a power supply, wait 60 seconds before turning it back on.
- Press the second power switch to the
ON(|) position and observe the LEDs on the second power supply faceplate. They should light as described in Step 4.
If the LEDs are not lit in the appropriate pattern after 60 seconds, repeat the power supply installation procedures described in Install an AC Power Supply, and the previous steps in this procedure.
