What is the Cisco 7576? The Cisco 7576 (see Figure 2) is similar in most respects to the Cisco 7513. The differences between the two models are found in the backplane and the interface processor slot numbering scheme (see Figure 3) on the card cage.
Upgrading a Cisco 7513 to a Cisco 7576 Upgrading a Cisco 7513 to a Cisco 7576 You can upgrade a Cisco 7513 to a Cisco 7576 with the Cisco 7576 Upgrade Kit (UPG-7513/7576=). The Cisco 7576 is similar to the Cisco 7513 except for the backplane and the interface processor slot numbering scheme located on the card cage. The upgrade kit does not include power supplies, RSPs, or interface processors. These all need to be transferred from your existing Cisco 7513 to the Cisco 7576.
Chassis Replacement or Upgrade Prerequisites Chassis Replacement or Upgrade Prerequisites Before you begin this installation, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. This section also provides a list of the tools that you need to perform the chassis replacement or upgrade. Safety Warnings Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement.
Safety Warnings Attention Ce symbole d'avertissement indique un danger. Vous vous trouvez dans une situation pouvant causer des blessures ou des dommages corporels. Avant de travailler sur un équipement, soyez conscient des dangers posés par les circuits électriques et familiarisez-vous avec les procédures couramment utilisées pour éviter les accidents.
Chassis Replacement or Upgrade Prerequisites Safety Guidelines The following guidelines will help to ensure your safety and protect the equipment. These guidelines are not inclusive of all potentially hazardous situations, so be alert. General Safety Precautions The following are general precautions for any workplace: • Do not perform any action that creates a potential hazard to people or makes the equipment unsafe. • • Do not work alone when potentially hazardous conditions exist.
Cable Strain Relief • Keep your back straight and lift with your legs, not your back. If you must bend down to lift the chassis, bend at the knees, not at the waist, to reduce the strain on your lower back muscles. • When lifting the chassis, grasp the underside of the chassis exterior with both hands. Do not attempt to lift the end of the chassis with the handles on the interface processor carriers; these handles are not designed to support the weight of the chassis.
Chassis Replacement or Upgrade Prerequisites • Ethernet interface cables use either slide-type locks or thumbscrews. Although all Ethernet Interface Processors (EIPs) ship from the factory with slide-type locks on each port, all EIPs also include conversion kits for replacing the slide-type locks with jackscrews to accommodate Ethernet interface cables with thumbscrews.

Replacing or Upgrading the Chassis • If you plan to mount or replace the chassis in an equipment rack, you also need the following tools: — Number 2 phillips screwdriver — 1/4-inch and 3/16-inch, flat-blade screwdrivers — ACS-7000RMK(=) rack-mount kit (with hardware) for the chassis (this kit also works for the Cisco 7000 chassis) • Whenever you remove or install processor modules, have the following equipment on hand to help prevent ESD damage: — Antistatic mat or antistatic foam pad in case you need t
Replacing a Rack-Mounted Chassis Assess your rack and lab configuration and the equipment you have available, and then choose the appropriate replacement procedure from the following: • If you have a spare rack-mount kit available and are able to install the new, empty chassis before you shut down and remove the existing one, follow the installation instructions provided with the rack-mount kit, Cisco 7513 and Cisco 7576 Rack-Mount Kit Installation Instructions (Publication Number 78-2023-xx).
Replacing or Upgrading the Chassis Figure 5 Chassis, Rack Brackets, and Ears M4 x 10-mm long Phillips flat-head screws (to attach ears to chassis) Bracket (2) POWER A POWER H3173 B We recommend that two people perform this procedure: one person should support the chassis while the other person removes the screws that secure the ears to the rack. Warning The chassis weighs approximately 75 pounds with just the blower module and card cage installed.
Replacing a Rack-Mounted Chassis Figure 6 Lifting the Chassis POWER A POWER H3118 B This completes the chassis removal procedure. If you have not yet installed the new chassis in the rack, proceed to the next section. Installing the New Chassis in the Rack Mount the chassis in the rack before connecting any interface or power cables. If possible, install the new, empty chassis in the rack first, and then install the system components from the old chassis.
Replacing or Upgrading the Chassis Figure 7 Sliding the Chassis into the Rack (Shown with Card Cage Assembly and Blower Installed) POWER A POWER H3177 B Step 4 Slide the chassis back into the rack along the ledges until the ears meet the front mounting posts on both sides of the rack. (See Figure 7.) Step 5 Secure each ear to the rack-mounting post with two 10-32 x 5/8-inch, phillips pan-head screws. This completes the procedure for moving the chassis into the rack.
Installing the Cable-Management Bracket Installing the Cable-Management Bracket The cable-management bracket attaches to the interface processor end of the chassis just above the card cage and below the blower module. (See Figure 8.) Use the bracket to keep network interface cables untangled and orderly, and to prevent cables from hindering access to interface processors in the interface processor slots.
Replacing or Upgrading the Chassis Step 2 Use a flat-blade screwdriver to loosen the two slotted screws approximately 1/8-inch. Step 3 Place the bracket over the screws (see Figure 8), and slide the bracket to the right. Step 4 Use a flat-blade screwdriver to tighten the screws. Step 5 When installing the network interface cables, route the cables up to and through the cable-management bracket.
Moving Processor Modules from the Old Chassis to the New Chassis Note We recommend that you refer to the “Port and Slot Configuration Worksheet” section on page 28 before you remove interface processors from the old chassis. This will ensure that you install them in the correct slots in the new chassis based on the configuration stored in NVRAM on the RSP. Although interface processors support OIR, you must wait at least 15 seconds after inserting an interface processor before inserting the next one.

Moving Processor Modules from the Old Chassis to the New Chassis To move the processor modules to the new chassis, follow these steps: Step 1 Before moving any processor modules, ensure that you have met the following prerequisites (refer to the “What is the Cisco 7513?” section on page 2” or the “What is the Cisco 7576?” section on page 3 for details): • On both chassis, ensure that the power is turned off and the power cable is disconnected from the AC power receptacle or the DC terminal block.
Replacing or Upgrading the Chassis Step 7 Place the processor module in the same slot position in the new chassis and align the notches along the edge of the carrier with the grooves in the slot. (See Figure 9a.) Step 8 While keeping the carrier at a 90-degree orientation to the backplane, carefully slide the carrier into the slot until the back of the faceplate makes contact with the ejector levers, and then stop. (See Figure 9b.) Do not use unnecessary force when installing processor modules.
Checking the Installation Checking the Installation To complete the replacement procedure, perform the following steps to verify that the system is functioning properly. These steps will also help you verify that all the processor modules you moved are returned to their previous state. For additional first-time startup troubleshooting procedures, refer to the Cisco 7500 Series Installation and Configuration Guide.
Replacing or Upgrading the Chassis If the system does not go on, check the following: If the system goes on, go to step 5. Step 5 Step 6 • Check the source power. Ensure that the power switch is completely in the On (|) position and that the power (input) cord is properly connected at both ends. • Check the fan OK LED. When on, this LED indicates the blower is operating.
Verifying the Installation Using show Command Descriptions and Examples When the system starts up and operates successfully, the replacement procedure is complete, and you can resume normal operation. If the system still fails to start up or operate properly, or if you isolate the cause of the problem to a failed component, contact a service representative for further assistance. Note After you verify a successful installation, gather the old chassis and any remaining spares and parts.
