Note The Cisco 7513 and Cisco 7576 use the same chassis, power supplies, cover panels, and accessories. Externally, the two models appear the same. However the backplane and interface processor slot numbering scheme are different. See Figure 1-19for an enlarged view of the Cisco 7576 interface processor slot numbering scheme. This area visually identifies which router model you have.

Cisco 7576 Dual CyBus Backplane

The Cisco 7576 features two dual CyBuses, creating two independent routers on one split backplane. The dual CyBus backplane, located at the rear of the removable card cage, provides the physical connections for the RSPs and interface processors, and transfers information at up to 2.134 Gbps (1.067 Gbps per CyBus) per router.
