PoE Ports

The RUGGEDCOM RS900GP supports eight 10/100Base-TX Power over Ethernet
(POE) ports (ports 1 to 8). Each port complies with the IEEE 802.3at and IEEE 802.3af
standards, and feature the ability to automatically enable/disable power when PoE-
capable devices are connected or removed.
The total allowable power budget for all PoE ports is dependent on the IEEE 802.3
standard required by the application:
If the power input is less than what is required, to prevent exceeding the power
budget, port priorities can be set via the RUGGEDCOM RS900GP 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 RS900GP User Guide" for the device.
For information about connecting a power source, refer to

Each PoE port features an LED that indicates the port's power and link/activity state.
