Carefully move the power cables out of the way.

Loosen the captive screw on each flange at the top and bottom of the power supply
faceplate completely.

10.

Grasp the handle on the power supply and pull firmly. Slide it halfway out of the chassis
(see Figure 91 on page 179).

WARNING:

Do not touch the power connectors on the rear of the power

supply (see “Rear of the Power Supply Showing Midplane Connector” on
page 174). They can contain dangerous voltages.

11.

Place one hand underneath the power supply to support it and slide it completely out
of the chassis.

CAUTION:

Each power supply weighs approximately 8.4 lb (3.8 kg). Be

prepared to support the full weight of the power supply as you remove it
from the router.
