The device can be mounted on virtually any VPX or VME module supporting the XMC mezzanine standard and uniquely enables designers of rugged embedded systems to integrate high-speed Ethernet switching functionality on space, weight and power (SWaP) optimised systems, as the 651 mezzanine module requires no additional chassis slot to deploy. The module is also available in a PMC mezzanine configuration (PMC-651) that provides up to 8 ports of managed GbE switching.
The XMC-651 supports full line-rate non-blocked Ethernet switching and the in-field management of a broad range of networking features including VLANs, multicast, and Quality of Service. Designed for use in rugged military environments, the module is available in both air-cooled and conduction-cooled variants and consumes under 7.5 watts with all 12 ports active.
The XMC-651 implements Ethernet switching functions via Broadcom 10th generation switching technology. Eight of the module’s ports support 10/100/1000Base-T with auto-negotiation. An additional 4 ports support SerDes (1000Base-BX) Gigabit Ethernet, offering flexibility in connecting in-chassis devices. The XMC-651 implements Layer-2 Ethernet switching with full wire-speed performance on all ports and features an 8K entry MAC address table, with automatic learning, advanced flow-control and head of line blocking prevention.
