Proceed to the next section to install the chassis in the rack.
Installing the Chassis in the Rack
Two people are required to lift the chassis and complete this part of the installation. You will need
to lift the chassis and slide it into the rack and onto the ledges provided by the brackets. After you
push the chassis back into the rack, you will attach the ears to the rack-mounting strips to prevent
the chassis from sliding forward or backward out of the rack.
Before moving the chassis, you must remove all power supplies and disconnect all power and
interface cables. If you are installing a new chassis, or if you have already removed all power
supplies and disconnected all interface cables, proceed to the section "Moving the Chassis into the
Rack" on page 22.
Removing Power Supplies and Interface Cables
Before moving the chassis, you must remove all power supplies and disconnect all power and
interface cables. Label the interface cables; you can use the configuration worksheet provided at the
end of this document 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.)
The power supply switch is also an interlock tab that prevents the supply from being removed when
it is on. (See Figure 6 on page 11.) The interlock tab extends into a slot in the chassis when the power
switch is on, and retracts into the power supply to allow removal when the switch is off.

While referring to Figure 12, position the ears on the chassis as follows:
•
To flush-mount the chassis (so that the end of the chassis is approximately flush with
the rack posts): Place each ear so that the mounting strips are flush with the end of the
chassis, and align the mounting holes in the ear with those in the chassis.
If you are attaching the ears to the noninterface processor end (front) of the chassis, the
mounting strips on the ears will extend slightly past the ends of the chassis. To protect
the plastic front bezel and LED windows, the front of the chassis will be slightly
recessed into the rack.
•
To center-mount the chassis (so that the chassis is roughly centered in a Telco-type
rack): Place each ear with the mounting strips away from the end of the chassis, and
align the mounting holes in the ear with those in the chassis.
Use two M4 x 10-mm, flat-head Phillips screws to secure each ear to the chassis.
Turn OFF all installed power supplies.
Disconnect the power cords from the source power connection first, then from the power
supply receptacle. Push the cable retention clip down to free the plug, then pull the cord out
of the power receptacle.
Loosen the captive installation screw at the top of the first power supply. (See Figure 13.)
Grasp the power supply handle and slowly pull the supply out of the bay. Keep your other
hand underneath the bottom to support it. (See Figure 13.)
Put the power supply aside.
