Curtiss-Wright Controls Defense Solutions is currently shipping the XMC-651, the embedded military market’s first managed XMC Ethernet Switch. The XMC-651 is a 12-port Gigabit Ethernet switch which 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 SWaP optimized 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.
