Managed Layer 2+ Ethernet Switch Module
EPS-12GMini is a managed Layer 2+ Ethernet switch module offering twelve 10/100/1000Mbps copper twisted
pair ports in the ultra-compact COM Express Mini form factor. It is ideal for rugged applications including industrial,
on-vehicle and military, where space is at a premium. The switch is based on Diamonds EPSM-10GX compact Ethernet switch module
and uses a same-size carrier board to provide the power and magnetics circuitry to create a complete switch solution.
This two-board design results in an ultra-compact size particularly suitable for UAVs and other unmanned vehicles.
All switch functions are managed by an embedded processor integrated into the switch. The processor
is accessed via an in-band web interface over one of the Ethernet ports or via an out-of-band command-line interface over
an RS-232 serial port. The integrated web interface provides an intuitive GUI for use in configuring and managing all
switch functionality. On-board memory holds dual application images, boot code, MAC addresses, and other parameters, and
can also be used for program execution.
EPS-12GMini includes two innovative features that enable automatic power savings. The switch can
detect unused Ethernet ports on network devices and power them down or place them in stand-by mode. Additionally,
the switch actively adjusts the power level needed based on cable length, saving energy on links shorter than the 100m
maximum specified length.
Input power is provided through the built-in, wide-range 6-34VDC power supply, enabling reliable operation
with industrial power sources as well as vehicle power systems.
EPS-12GMini was designed for use in vehicle and harsh environment applications. All I/O connectors are
latching, providing enhanced reliability over the RJ-45 connectors used in commercial Ethernet switches. The -40ºC to +85ºC
operating range makes itsuitable for use in outdoor and vehicle applications.
EPS-12GMini comes loaded with all required firmware, enabling its immediate operation without any
EPS-12GMini comes with an integrated heat sink for cooling. An optional heat spreader is available for
direct mounting to enclosure walls.
A cable kit provides all necessary cables for operation. The Ethernet cables provide panel-mountable RJ-45
sockets, while the serial port cable provides the industry-standard DB9F connector. The power cable provides tinned leads for
easy adaptation to various power sources.
