PoE Ports
The RUGGEDCOM RS900GPF 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:
Standard
Power Budget
IEEE 802.3at
255 W
IEEE 802.3af
135 W
If the power input is less than what is required, to prevent exceeding the power
budget, port priorities can be set via the RUGGEDCOM RS900GPF 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 RS900GPF User Guide
for the device.
For information about connecting a power source, refer to
LEDs
Each PoE port features an LED that indicates the port's power and link/activity state.
