NETernity™ CP921RC is a Fully Managed Layer-2/3+ Gigabit Ethernet embedded switch offering full IPv6 wire speed switching and routing and featuring our exclusive OpenWare™ switch management environment. CP921RC has 24 rear I/O Gigabit Ethernet ports. Designed to meet the needs of a wide range of challenging applications such as networked Telecom systems, the 6U CompactPCI form factor CP921RC facilitates communications within a chassis as well as supporting the network outside the chassis. It is PICMG 2.16 and RoHS compliant, and supports high-availability hot swap as well as IPMI v1.5.

CP921RC delivers full wire-speed Gigabit Ethernet switching that can be fully managed and easily deployed. Proven, high-performance architecture and a multilayer switching fabric provide a rich feature set, broad functionality, scalability, and product life longevity. Based on a PowerPC management processor and a leading high-performance switch fabric, the CP921RC has integrated Layer-2/3+ switching capabilities as well as the ability to support higher Layer 4-7 functionality when required. IPv6 brings improved security, reliability and flexibility, enhanced support for mobile computing devices, and larger address space for global reach and scalability to applications. In the near future, support for IPv6 will be required for Military and Defense customers, and because this switch also supports IPv4 it offers a path forward which protects existing investments. OpenWare™ is available exclusively on selected NETernity Fully Managed Layer-2/3+ Ethernet switches. Comprehensive and powerful, this switch management environment provides integrated management services including configuration, monitoring, switching control, addressing, routing and all supported protocols. Configuration and monitoring functions are accessible from a serial console or via a network. Supported access methods include Telnet, SSH and SNMP.

A version of the switch (CP921RC-F offers a Failover Group (FOG) capability to direct one of the ports across the fabric-to-fabric link on the PICMG 2.16 backplane to support inter-switch communication, enabling features like switch redundancy. The CP921RC-F must be used with the new TRCP9XX-5RC-F Rear Transition Module (RTM).
