This document contains instructions for replacing a Cisco 7000 and Cisco 7507 chassis as a spare
part.
Note With a few exceptions, the chassis replacement procedures are identical for both chassis;
therefore, throughout this document, both chassis are referred to as the chassis; the exceptions are
clearly noted.

Prerequisites Safety Guidelines The following guidelines will help to ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert. Warning Before working on a system that has an on/off switch, turn OFF the power and unplug the power cord. (For translations of this safety warning, refer to the section “Power Disconnection Warning” on page 36.) Warning Do not touch the power supply when the power cord is connected. For systems with

Prerequisites Lifting the Chassis Safely The chassis weighs 76 pounds when empty (no processor modules or power supplies installed) and 145 pounds when fully configured with two power supplies and all interface slots populated. Whenever you lift the chassis or any heavy object, follow these guidelines: Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not yo

Prerequisites Safety with Electricity Follow these basic guidelines when working with any electrical equipment: • Before beginning any procedures, locate the emergency power-off switch for the room in which you are working. • Never assume that power has been disconnected from a circuit; always check. • Always disconnect all cables (including network interface and telephone wiring) and remove all power supplies before moving or lifting the chassis. Warning Always disconnect all cables before movi

Prerequisites • Multimode Fiber Distributed Data Interface (FDDI) connectors use small plastic arms on two sides of the connector that act like springs and are constrained by the inside of the connector port. To remove a multimode cable from a FIP port, pinch the two plastic arms inward while pulling the connector out of the port. When removing any cable, pull the cable out at the connector; never pull or tug on the cable itself. For detailed descriptions of the interface connectors and ports, r

Unpacking the Chassis Following are guidelines for preventing ESD damage: • Always use an ESD strap and ensure that it makes good skin contact. • When removing or installing an LED board, connect the equipment end of the ground strap to an unpainted surface of the chassis, such as the vertical metal frame that is exposed when the front chassis panels are removed. • Handle boards by the edges only; avoid touching the board components, traces, or connector pins. • Place a removed board component-s

Replacing a Rack-Mounted Chassis • If there is sufficient space available in the same rack (or an adjacent rack) to install the replacement (empty) chassis before you remove the existing system, you can minimize downtime and avoid having to disconnect network interface cables by leaving the existing system operating while you install the replacement chassis in the rack. Just ensure that both chassis, when installed, will be close enough to avoid straining cables connected to the interface process

Replacing a Rack-Mounted Chassis Adding a New Chassis to the Rack If there is sufficient rack space to install the replacement chassis before you remove the existing system, proceed as follows. Step 1 Follow the instructions in the section “Unpacking the Chassis” on page 11 to unpack the rack mounting hardware and, after the mounting hardware is installed, to unpack the chassis. Step 2 Ensure that there are at least 20 inches of vertical space free in the rack above or below the existing system,

Replacing a Rack-Mounted Chassis Caution To prevent damage, never attempt to lift or support the front of the chassis with the plastic front panels. The panels can break away and allow the chassis to drop. Step 9 To remove the empty chassis from the rack, position one person in the back of the rack to push the chassis out the front, and position two people in front of the rack to support the chassis as it is pushed forward out of the rack. Caution The following step might shift the chassis’ cent

Replacing a Rack-Mounted Chassis Caution If the existing chassis is installed in an enclosed rack, or if a power strip or other rack fixture blocks access to the power supply bays, you might have to remove the existing system with the power supplies intact, and then install them in the replacement chassis before you install that chassis in the rack. Ensure that you have sufficient assistance to support the chassis and to prevent the rack from tipping while you move the chassis into or out of the r

Replacing a Rack-Mounted Chassis Step 5 On the front of the rack, use a 1/4-inch flat-blade screwdriver to loosen and remove the four binder-head screws that secure the left and right ears to the front mounting strips on the equipment rack. (See Figure 7.) Keep the removed screws together; you will need them to secure the replacement chassis in the rack.

Replacing a Rack-Mounted Chassis Step 6 Position one person in the back of the rack to push the chassis out the front, and position two people in front of the rack to support the chassis and lower it to the floor as it is pushed forward out of the rack. Slowly push the chassis out of the front of the rack while the two assistants in the front of the rack grasp the chassis along the metal undersides behind the plastic front panels. When the chassis is clear of the rack, lower it to the floor. Step

Moving System Components Moving System Components The following sections describe the procedures for removing each processor module and power supply from the old chassis and installing it in the new chassis. Move and install all processor modules before you move the power supplies. If you removed your existing chassis from an equipment rack, the power supplies should already be removed; however, do not install them in the replacement chassis until all processor modules are installed.

Moving System Components Failure to use the ejector levers could result in a partial backplane connection and subsequent system crash. Also, be sure to tighten both the top and bottom captive installation screws on each module to ensure that it will remain seated properly. When replacing components, work from right to left. When you remove a processor module, immediately install it in the new chassis and secure it in the identical slot before removing the next processor module. Before removing p

Moving System Components Step 2 Place your thumbs on the upper and lower ejector levers and simultaneously push the top lever up and the bottom lever down to release the board connector from the backplane. (See Figure 8c.) Step 3 Grasp the carrier handle with one hand and place your other hand under the carrier to support and guide it out of the slot. (See Figure 9.) Avoid touching the board or any connector pins. Figure 9 Handling a Processor Module During Installation Step 4 Carefully pull the
