"Installing the New Card Cage and Backplane Assembly."
Installing the New Card Cage and Backplane Assembly
To install the new card cage and backplane assembly, follow these steps:

Location of the EEPROM Devices on the Rear of the Card Cage (Cisco 7576)
EEPROM B
Pin 1
The Cisco 7576 features two routers on one backplane. These are designated
Note
router A and router B. The backplane of the Cisco 7576 includes two dual arbiters, two
chassis interfaces, and two EEPROM devices. Figure 13 shows the specific location and
designation of each EEPROM device.
Remove the old EEPROM device(s) from the old card cage, note where pin 1 is, and
immediately install them on the EEPROM socket on your new card cage. (See Figure 12
for the Cisco 7513 or Cisco 7513-MX, and Figure 13 for the Cisco 7576.)
Install the blank EEPROM device(s) (that you removed from your new card cage and
marked with tape) on the EEPROM socket on your old card cage; remove the small piece
of tape from the blank EEPROM device(s). Return the old card cage to Cisco.
Repeat Step 2 through Step 6 for the second EEPROM device in the Cisco 7576.
To install the new card cage and backplane assembly, carefully lift the assembly, place it
into the chassis opening, and slide the assembly into the chassis opening until the left and
right flanges on the card cage are flush with the chassis flanges. (See Figure 14.)
Squeeze the card cage and chassis flanges together and tighten each captive screw.
(See Figure 14.) Do not overtighten the captive screws.
