Remove an AC Power Supply

To remove an AC power supply, follow this procedure (see Figure 3 and Figure 4):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. Make sure the router is attached to a proper earth ground.
2. Press the power switch on the power supply faceplate to the OFF (O) position.

   If you are not removing the power supply, but simply powering it off, wait at least 60 seconds before turning it back on. If you need to power it off again, wait for at least 60 seconds after powering it on.

3. Unplug the power cord from the appliance inlet on the faceplate.
4. Loosen the thumbscrew at each corner of the power supply faceplate, using a Phillips screwdriver if necessary.
5. Grasp the handle on the power supply faceplate and pull firmly to slide the unit about halfway out of the chassis.
6. Place one hand under the power supply to support it, then slide it completely out of the chassis.
