The Cisco 7513, Cisco 7513-MX, and Cisco 7576 card cage holds the processor modules used by

chassis interface are printed circuit boards that are attached to the rear of the backplane. The dual

arbiter and chassis interface are replaced when the card cage and backplane assembly is replaced.

The Cisco 7576 is a dual independent router system that includes two dual arbiters, two chassis

interfaces, and two EEPROM devices.
