(RS422), 1-pps RS422 or 1.0/2.3 50-ohm RF connector, in/out, and 10-MHz 1.0/2.3 50-ohm RF connector, in/out. Note: The NC55-RP is now End of Sale and NC55-RP-E will End of Sale in May 2024. The NCS55-RP2-E is the third generation of the RPs. It is compatible with all the three modular form factors. It supports Class C timing. This will require all the line cards in the chassis to be Class C capable. With a mix of Class C and non-Class C line cards, the chassis falls back to Class B. It is supported from IOS XR 7.3.1. Figure 6. Route processor NC55-RP-E Figure 7. Route processor NC55-RP2-E The NCS 5500/5700 can host two route processor modules, though only one route processor is active at a time. The other route processor operates in standby mode, ready to assume control if the primary fails, providing stateful switchover. RP-E and RP2-E are supported with both version-1 and version-2 Fans and Fabric cards. The route processor’s high-speed multicore CPU and large memory base builds the foundation for a highly available platform and provides very fast convergence in case of failure. The route processor runs Cisco’s 64 - bit IOS XR operating system. The 64-bit IOS XR enables better processing performance and faster access to system memory. It also provides the ability to create containers to run third-party applications. These advantages plus the new feature enhancements such as telemetry, programmability, and flexible packaging in IOS XR builds a solid foundation for NCS 5500/5700 platforms. Out-of-band management is available via a 10/100/1000-Mbps Management Ethernet interface and a serial RS-232 console port. There are two USB 2.0 interfaces that can be used for disaster recovery and also to transfer system images and logs. The communications between the route processor and the fabric modules or line cards utilize either Ethernet Out-of-Band Channel (EOBC) or Ethernet Protocol Channel (EPC). Both channels have a central hub on the system controllers providing redundant paths. Table 2.
