EPSM-12G2F is a managed Ethernet switch module in an ultra-compact 2.2″ x 3.3″ (55 x 84mm) size offering 24 10/100/1000Mbps copper ports and 2 1-2.5Gbps SFP ports. It supports an embedded software package offering a full suite of Layer 2 managed Ethernet switching capabilities. The module is intended to be used on a carrier board to implement a complete Ethernet switching solution. The core Ethernet switching technology is almost fully encapsulated on the module; for many applications, only the “last inch” of magnetics and I/O connectors is required to complete the circuit, enabling easy development of custom form factor compact, rugged Ethernet switch solutions.
EPSM-12G2F offers compelling advantages over in-house designed Ethernet switches requiring mid-range software features:
EPSM-12G2F includes the feature-rich WebStaX Layer 2 managed Ethernet switch software.
Two cooling accessory options are available: A heat sink provides convection cooling in a low profile, while a heat spreader provides improved conduction cooling for superior high temperature performance in applications where physical contact with the system enclosure is available.
A design guide is available with circuit details and other technical information necessary to design a carrier board around the EPSM-12G2F. A development kit is also available including:
