CP6940 is a fully managed layer 2 and 3 1/10/40 Gigabit Ethernet switch for CompactPCI® and VME embedded systems. It is designed for long-term programs and use in harsh environments and in an extended temperature range from -40°C to +70°C. It is ideally suited for multi-CPU high-performance servers in the aerospace or defense sector as well as for communication networks of all types.

CP6940 is the widely compatible successor of CP6924 and CP6930, developed and manufactured in Europe.

 More uplinks, higher bandwidth, improved management
 QSFP+ for 40G or 4x 10G
 SFP+ multi-rate 1/2.5/5/10GBase-x
 RJ45 and SFP 1G front uplinks
 24x extended fabric links CPCI PICMG2.16 and VME VITA31.1
 4 MByte fully integrated packet buffer
 Robust: VITA 47 class EAC6 V2 and extended temperature
 Reliable: hot swap, IPMI, SNMP, built-in tests, maintenance

Optimized for multicast communication

Burst absorption is the key, handling of several multicast data streams at the same time. That’s where CP6940 is tailored for by its non-blocking architecture and line rate for all packet sizes; by 4 MByte fully integrated packet buffer; by the intelligent memory management unit (MMU) optimized for handling of bursty data traffic; and by dynamic memory allocation.

Broadcom technology and separate CPU to avoid limitations

The CP6940 design relies on Broadcom's highly integrated single-chip switch technology. By using a separate high-performance QorIQ® microcontroller, limitations are avoided which could be observed when using only the switch silicon integrated CPU; in particular, performance of the management systems, response times on SNMP requests. Also, the CPU makes CP6940 prepared for future upgrades and extensions, which is important for long time available switches. 

Full Layer 2 and 3 management

CP6940 can be monitored via SNMP. A comprehensive command line interface provides easy management and remote configuration by either serial or network interface. Supported features are: IPv4/optionally IPv6 forwarding & multicast, routing & switching, Quality of Service, VLANs, Spanning tree (STP, RSTP, MSTP, PVST, RPVST) time synchronization using 802.1AS, access control, extended user management and many more.
