The CP3923 is a fully managed layer 2/3 Gigabit Ethernet switch offering IPv4/IPv6 routing and full management capabilities. It supports a powerful set of CLI, Telnet, Web and SNMP management interfaces to configure the entire set of protocols and parameters including Layer 2 and Layer 3 (IPv4/IPv6*) protocols, Multicasting, QoS and Security.
On top of that, the CP3923 maximizes the reliability of rugged COTS applications by supporting Intelligent Platform Management (IPMI) and hot swap capabilities.

Eight GbE ports to the rear and up to eight GbE to the front ensure highest connectivity capabilities. The CP3923 is available with three different front I/O versions:
Either with eight GbE ports via RJ45 (CP3923-8C) or for mobile- and transportation-oriented applications with four (CP3923-4M) or eight (CP3923-8M) Fast Ethernet ports via M12-D connectors.
For applications requiring outmost mechanical stabilitiy and reliability the CP3923 is also available as rugged, conductive-cooled version (CP3923-RC).
