Cisco Systems Cisco 7000, Cisco 7507 installation instructions Installing the Chassis in the Rack

Installation

Follow these steps to install the ears on the chassis:

Step 1 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.

Step 2 Use two M4 x 10-mm, flat-head Phillips screws to secure each ear to the chassis.

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.

Follow these steps to install the chassis in the rack:

Step 1 Turn OFF all installed power supplies.

Step 2 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.

Step 3 Loosen the captive installation screw at the top of the first power supply. (See Figure 13.)

Step 4 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.)

Step 5 Put the power supply aside.
