Figure 1-17 shows details on the rear, interface-processor end of the Cisco 7576.
Figure 1-17 Cisco 7576 (Rear View)
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 1-19 for 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.
