The XMC-651 and PMC-651 are Gigabit Ethernet switches packaged in the industry-standard XMC and PMC form factors. They are 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 651 family offers a zero-slot Ethernet switching solution that can be added to most basecards with an XMC or PMC 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.
