CAUTION: Do not leave a power supply slot empty for more than a short time
while the router is operational. The power supply must remain in the chassis
for proper airflow.
To remove an AC power supply (see Figure 65 on page 178):
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. Verify that the router is attached to
a proper earth ground.
2. Press the power switch on the power supply faceplate to the OFF (O) position.
NOTE: If you are not removing the power supply, but simply powering it
off,wait atleast 60 seconds beforeturning 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.
