Caution

card cage and backplane assembly is removed from the chassis. To prevent damaging these

components, place the card cage and backplane assembly on an antistatic mat or foam, and place the

assembly in the same orientation as when it is mounted in the chassis. (See Figure 11.)

This completes the procedure for removing the old card cage and backplane assembly; proceed to

the next section, "Exchanging the EEPROM Devices."

Exchanging the EEPROM Devices

Before you install your new card cage, you must exchange the new EEPROM device(s) on the rear

of the new card cage for 00the old EEPROM device(s) on the rear of your old card cage. The

Cisco 7513 and Cisco 7513-MX include one EEPROM device and the Cisco 7576 includes two

EEPROM devices, one for router A and one for router B. The EEPROM device(s) on your old card

cage have MAC addresses programmed into them, which are necessary for your system to function

properly, and these old EEPROM device(s) are required for your system.
