What are the different ports available on the NRP and what are their functions?
A. The NRP1 has the following ports: standard Cisco console and auxiliary ports. It has a 10-BaseT Ethernet for network management. It has a 10/100 Fast Ethernet port for connection to external networking and data storage. It has an ATM OC-3 speed interface to the backplane, switch to switch fabric on the NSP through the backplane. It has a backplane Ethernet (BPE) to communicate with other cards on the chassis. The BPE is used to communicate with the NSP and other NRP’s. The NRP2 has only a gigabit Ethernet physical interface. A gigabit interface converter (GBIC) module and connector is required. Supported GBIC types include 1000BaseSX/LX/LH/ZX. Console access to the NRP2-SV is done through the NSP in the Cisco IOS software, refer to Methods for accessing the NRP2-SV. The NRP2-SV has a 622 Mbps ATM backplane interface. It uses the PAM mailbox which is a serial interface for internal system communication.
