Warning To avoid dropping the power supply and injuring yourself, use both hands to remove or install a power supply. Each power supply weights approximately 20 pounds (9.1 kg).

Step 7 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.)

Step 8 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.

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 To avoid damaging power supplies and interface processors, never attempt to lift the 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.
