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
