PoE Ports

The RUGGEDCOM RST2228P supports up to twenty-four 10/100/1000 Mbps Power
over Ethernet (PoE) ports powered by an external power supply. Each port complies
with the IEEE 802.3af and IEEE 802.3at standards and features auto-sensing and
automatic power off when cables are removed.
The total allowable power budget for all ports is 500 W. If the external power supply
is less than the PoE power demand, to prevent exceeding the power budget, port
priorities can be set via the RUGGEDCOM ROS operating system to disable low
priority ports when demand is too high. Ports can also be enabled/disabled and
placed on a power schedule to conserve power. For more information, refer to the
RUGGEDCOM ROS Configuration Manual for the RUGGEDCOM RST2228P.
