Cisco uBR7200 NPE with 256MB Memory, 64MB Flash, 3 GE/FE/E and I/O Ports.
The Cisco uBR7200-NPE-G1 includes three Ethernet interfaces as part of the system CPU. These interfaces, which can run at any speed from 10 Mbps Ethernet to 1000 Mbps Gigabit Ethernet, are also on the same piece of silicon as the system CPU. There is no bus bottleneck because the interfaces feed directly into the CPU at extremely fast internal chip speeds. High-speed LAN interfaces that once had to share peripheral component interconnect (PCI) bus bandwidth with other port adapters and I/O controllers can be moved to the processor to free up bus bandwidth for WAN port adapters.
Cisco’s modular uBR7200-NPE-G1 incorporates all the functionality of an I/O controller and no longer requires the use of one either. This money saving feature has auxiliary, Flash memory, and console ports. If an I/O controller is detected in the I/O controller slot, all I/O controller functionality defaults to the I/O controller.
