Replacing an AC Power Cord

To replace the power cord for an AC power supply, follow this procedure:

1. Locate a replacement power cord with the type of plug appropriate for your geographical location (see AC Power, Connection, and Power Cord Specifications).
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. Verify that the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
3. Press the power switch on the power supply faceplate to the OFF (O) position.
4. Unplug the power cord from the appliance inlet on the faceplate and from the power source receptacle.
5. Insert the appliance coupler end of the replacement 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.
6. Press the power switch on the power supply faceplate to the ON ( | ) position. Verify that the green OK LED eventually lights steadily and the amber FAULT LED does not light.

   Note: When two power supplies are installed, at least one Routing Engine and one FPC must also be installed for both power supplies to power on. In the absence of this minimum load, only one power supply starts. (The router powers on and operates correctly with one power supply, but without the redundancy benefit of a second power supply.)
