Cisco 6400 System
The Cisco6400 uses a ten-slot, modular chassis featuring the option of half-height and full-height card
and slot redundancy, along with dual, fault-tolerant, load-sharing AC or DC power supplies. The two
central slots (slot 0A and 0B) in the Cisco6400 are dedicated to redundant, field-replaceable NSP
modules that support the 5-Gbps shared memory, fully nonblocking switch fabric. The NSP also
supports the feature card and high-performance reduced instruction set computing (RISC) processor that
provides the central intelligence for the device. The NSP supports a variety of backbone and wide-area
interfaces.
The remaining slots support up to eight node route processors (NRPs), full-height node line cards
(NLCs), or carrier modules for half-height NLCs. NRPs and NLCs can be configured for redundant
operation. As a result, you can have multiple redundant pairs of NRPs and NLCs, or any combination of
nonredundant NRPs and NLCs. The NRPs are fully functional router modules capable of terminating
PPP sessions delivered over OC-12, OC-3, or DS3 node line cards.
