Proceed to the next section to move the chassis into the rack.
Moving the Chassis into the Rack
Two people are required to lift the chassis and insert it into the rack. The chassis weighs
approximately 105 pounds (47.62 kg) when the power supplies are removed. Make sure that your
path to the rack is not obstructed.
You will insert the end of the chassis that does not have the ears attached into the rack, lower it onto
the two ledges on the brackets, then slide the chassis back until the ears meet the rack-mounting
posts. The chassis feet are not needed on a rack-mounted chassis. You can remove the feet after you
lower the chassis into the rack, but before you slide it fully back into position. The center of the foot
has a slot for a screwdriver, and a 7/16-inch nut is fused to the stem of the foot. (See Figure 14.)
Alternatively, you can simply leave the feet attached.
Caution
chassis using the handles on the power supplies or the interface processors. These handles are not
designed to support the weight of the chassis. Using them to lift or support the chassis can result in
severe damage to the equipment and serious bodily injury.

If a second power supply is installed, repeat steps Steps 3 through 5 to remove the second
supply.
Handling a Power Supply (AC-Input Power Supply Shown)
To avoid dropping the power supply and injuring yourself, use both hands to remove or
Label and disconnect all interface cables. You can make a copy of the configuration
worksheet provided near the end of this document, and use it to record the correct cable
connections and avoid crossing cables when you reconnect them. (For the Cisco 7000, see
Figure 16 on page 27, and for the Cisco 7507, see Figure 17 on page 28.)
On the rear of the chassis, check the ejector levers and captive installation screws on all
installed interface processors and interface processor fillers to ensure that all are secure.
To avoid damaging power supplies and interface processors, never attempt to lift the
