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
