This document contains instructions for replacing a Cisco 7000 and Cisco 7507 chassis as a spare
part.
Note
therefore, throughout this document, both chassis are referred to as the chassis; the exceptions are
clearly noted.
You will remove the processor modules and power supplies from your existing chassis and install
them in the replacement chassis. The term processor modules refers to the RP, SP (or SSP), and
interface processors in the Cisco 7000, and the RSP2 and interface processors in the Cisco 7507.
These instructions are applicable only to systems that are already operational and for which first-time
installation and startup verification has been performed. If you have not already installed the system
and verified that it operates properly, or if you are moving the chassis to a new location, refer to the
Cisco 7000 Hardware Installation and Maintenance or Cisco 7507 Hardware Installation and
Maintenance publications for installation information.

Page 6: Prerequisites
Prerequisites Prerequisites Before you move a chassis or any of the system components, review the safety guidelines and requirements in this section and ensure that you have the necessary parts and tools you will need. Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. -
Page 7: Safety Guidelines
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. - Page 8 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: Two people are required to lift the chassis.
- Page 9 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. •...

Page 10: Preventing Electrostatic Discharge Damage
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. -
Page 11: 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. - Page 12 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.
- Page 13 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.
- Page 14 Replacing a Rack-Mounted Chassis To prevent damage, never attempt to lift or support the front of the chassis with the plastic Caution front panels. The panels can break away and allow the chassis to drop. To remove the empty chassis from the rack, position one person in the back of the rack to Step 9 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.
- Page 15 If the existing chassis is installed in an enclosed rack, or if a power strip or other rack Caution 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.
- Page 16 Replacing a Rack-Mounted Chassis On the front of the rack, use a 1/4-inch flat-blade screwdriver to loosen and remove the four Step 5 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.
- Page 17 Position one person in the back of the rack to push the chassis out the front, and position Step 6 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.

Page 18: Moving System Components
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;... - Page 19 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.
- Page 20 Moving System Components Place your thumbs on the upper and lower ejector levers and simultaneously push the top Step 2 lever up and the bottom lever down to release the board connector from the backplane. (See Figure 8c.) Grasp the carrier handle with one hand and place your other hand under the carrier to Step 3 support and guide it out of the slot.
- Page 21 While keeping the carrier at a 90-degree orientation to the backplane, carefully slide the Step 6 carrier into the slot until the back of the faceplate makes contact with the ejector levers. (See Figure 8b.) Using the thumb and forefinger of each hand, simultaneously push the top lever down and Step 7 the bottom lever up 90 degrees to fully seat the board connectors in the backplane.
- Page 22 Moving System Components Use both hands to handle power supplies. Each weighs 20 pounds. If the power supply resists Note when you attempt to pull it out of the bay, the switch is probably not fully in the OFF (O) position, or the captive installation screw at the top of the supply is not fully loosened.
- Page 23 To secure the AC-input cable in the power supply AC receptacle, push up the cable Step 13 retention clip up until it snaps into place around the connector. To secure the DC-input cable to the power supply, attach the three leads to the terminal block, and then attach two nylon cable ties around the DC-input cable and the bracket near the terminal block.

Page 24: Verifying The Installation
Verifying the Installation Verifying the Installation This section provides instructions for first ensuring that all connections are secure and then for restarting the system and verifying that it operates correctly. If the system does not start up and operate as expected, the troubleshooting procedures in this section will help you isolate the cause of the problem. - Page 25 After turning on the lower power supply, turn ON the upper power supply (if one is present) Step 2 for redundant power. The upper power LED on the front of the chassis will go on. While the system initializes, the boot error LED on the RP (or the CPU halt LED on the Step 3 RSP2 and RP) goes on for about five seconds or less, then goes out when the boot is complete.
-
Page 26: Troubleshooting The Installation
Verifying the Installation Troubleshooting the Installation Follow the procedures in this section if the system does not restart and boot as expected. Most often, problems you encounter while replacing the components in a new chassis are caused by power supplies or processor modules that are not properly installed and therefore are not connected properly inside the chassis. - Page 27 In systems with a single DC-input power supply, and in systems with redundant power when both power supplies are shutting down, the out fail LED goes on momentarily as the system ramps down, but goes out when the power supply has completely shut down. In systems with redundant power and one power supply still active, the out fail LED on the failed power supply will remain on (powered by the active supply).
- Page 28 Verifying the Installation In systems with a single power supply, and in systems with redundant power when both power supplies are being shut down, the DC fail (or output fail) LED goes on momentarily as the system ramps down, but goes out when the power supply has completely shut down. In systems with redundant power and one power supply still active, the DC fail (or output fail) LED on the failed power supply will remain on (powered by the active supply).
- Page 29 Verifying the Installation Route Processor LEDs (Cisco 7000) Figure 15 shows the LEDs on an RP installed in the chassis. The three LEDs on the RP indicate the system and RP status. When the system is turned on or restarted, the boot error LED goes on for one or two seconds, then goes out.
- Page 30 Verifying the Installation Route Switch Processor LEDs (Cisco 7507) Figure 16 shows the two LEDs on the RSP2. They indicate the system and RSP2 status. The normal LED goes on to indicate that the system is operational. During normal operation, the CPU halt LED on the RSP2 should be off and stay off unless the system detects a processor hardware failure.
- Page 31 Interface Processor, SP, and SSP LEDs The SP or SSP (on the Cisco 7000) and all interface processors contain an enabled LED. When on, this LED indicates that the SP or interface processor is operational and that it is powered up. It does not necessarily mean that the interface ports on the interface processors are functional or enabled.
- Page 32 Verifying the Installation Listen for the system blower. It generates about 60 dB, so you should immediately hear it Step 3 start operating. If you determine that the power supplies are functioning normally and that the blower is faulty, contact a service representative. If the system blower does not function properly at initial startup, there are no installation adjustments that you should make.
- Page 33 When the system boot is complete, the RP (or RSP2) begins to initialize the interface Step 7 processors. During this initialization, the LEDs on each interface processor behave differently (most flash on and off). The enabled LED on each interface processor goes on when initialization has been completed.
