Removing and Replacing Processor Modules Removing and Replacing Processor Modules Before you can replace the card cage and backplane assembly, you need to remove all processor modules installed in the card cage, and then replace them after the new card cage assembly is in place. The term processor module refers to the RSP2, RSP4, or RSP8 and all interface processors. Note Always use the ejector levers when installing or removing processor modules. A module that is partially seated in the backpla

Replacing Processor Modules Figure 6 Board Rack with Processor Modules Caution To prevent damage to the processor modules, do not stack them on top of each other. Replacing Processor Modules You can replace an interface processor in any of the 11 interface processor slots, 0 through 5, and 8 through 12, from left to right. (See Figure 1.) slot 6 and slot 7 are reserved for the RSP. Blank processor module fillers are installed in slots without processor modules to maintain consistent airflow throug

Removing Power Supplies Caution Always install blank processor module fillers in empty processor slots to maintain the proper flow of cooling air through the chassis. Step 7 Use a screwdriver to tighten both captive installation screws on each processor module. Step 8 Attach network interface cables or other devices to the interface ports. Use the notes you made in the “Port and Slot Configuration Worksheet” section on page 23. Step 9 After you reconnect power and turn it on, check the status of th

Exchanging the EEPROM Devices Caution The new EEPROM device(s) that shipped on your new card cage are blank. Note Do not perform these steps if you are upgrading a Cisco 7513 to a Cisco 7576. These instructions apply only to the replacement of an equivalent card cage. The following procedure requires you to first exchange the blank EEPROM device(s) on your new card cage for the old EEPROM device(s) from your old card cage, and then place the blank EEPROM device(s) on your old card cage for return
