Install an AC Power Supply

To install an AC power supply, follow this procedure:

1. Verify that the switch on the power supply faceplate is in the OFF (O) position.
2. Locate the power cord shipped with the router, which should be appropriate for your geographical location (see AC Power Cord Specifications).
3. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
4. Grasp the handle on the power supply faceplate with one hand and place the other hand under the unit to support it.
5. With a finger of the hand that is grasping the handle, lift and hold up the safety interlock lever, which is just below the appliance inlet.
6. While holding the safety interlock lever up, slide the power supply into the chassis until it contacts the backplane.
7. Still holding the safety interlock lever up, turn the extractor/inserter clockwise until the power supply engages with the connectors on the backplane.
8. Push the safety interlock lever down.
9. Using a Phillips screwdriver, tighten (but do not overtighten) the thumbscrew at each upper corner of the power supply faceplate.
10. Insert the appliance coupler end of the power cord into the appliance inlet on the power supply faceplate and insert the plug into an AC power source receptacle. Verify that the power cord does not block access to router components or drape where people could trip on it. 
11. Press the power switch on the power supply to the ON ( | ) position. Verify that the green LED labeled OK on the power supply faceplate eventually 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 chassis commands, 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. If the router is completely powered down 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 down the router again, first issue the CLI request system halt command. 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.
