Replacing an AC Power Supply Cord

To replace the AC power cord for a redundant power supply:

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 the ESD point on the chassis, or to an outside ESD point if the router is disconnected from earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
3. Press and release the power button to power off the router. Wait for the POWER LED to turn off.

   If the power supply is a redundant power supply in a J6300 Services Router, you can leave the router powered on and power flowing in the alternate power supply.

4. Unplug the power cord from the power source receptacle.
5. Unplug the power cord from the appliance inlet on the power supply faceplate.
6. Insert the appliance coupler end of the replacement power cord into the appliance inlet on the power supply faceplate.
7. Insert the power cord plug into an AC power source receptacle.

   Each power supply must be connected to a dedicated AC power feed. For information about connecting to AC power sources, see Connecting Power.

8. Verify that the power cord does not block access to Services Router components or drape where people might trip on it.
9. Press and release the power button to power on the router. Verify that the POWER LED lights steadily after you press the power button.
