The XMC/PMC-651 12-port Gigabit Ethernet Switch is designed to support "in-chassis" networks with managed Layer-2 switching capabilities. Part of a family of Gigabit Ethernet switching/routing products from Curtiss-Wright Defense Solutions, the XMC-651 XMC/PMC Ethernet Switch is an ideal low cost zero-slot Ethernet switching solution that can be added to any basecard with an XMC mezzanine slot. These switches are designed for rugged applications with backplane I/O and are offered in a full range of ruggedized air- and conduction-cooled versions.

The XMC-651 and PMC-651 both offer 8 ports of Gigabit Ethernet supporting tri-speed 10/100/1000Base-T with auto-negotiation and auto-MDI/MDIX crossover support. For some XMC variants, an additional 4 ports are offered, supporting SerDes (1000Base-X) GbE, providing flexibility when connecting in-chassis devices.

The XMC/PMC-651 family supports Layer-2 multicast, where a single source device can send data to multiple destination devices. This technique is extremely powerful when distributing data such as video and telemetry information. The PMC/XMC-651 Ethernet Switch family offers full support for jumbo frames up to 9K bytes.

The 651 family connects only to the XMC and PMC connectors to obtain power and for Ethernet I/O connections. No software driver is needed.
