PoE Ports

The RUGGEDCOM RSG920P supports four Power over Ethernet (POE) ports (ports
13 to 16) powered by an external power supply. Each port complies with the IEEE
802.3at standard.
The total allowable power budget for all ports is 120 W. If the external power supply
is less than 120 W, 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 RSG920P.
For information about connecting the external power supply, refer to "Connecting
External PoE Power" (Page 18).
LEDs
Each PoE port features an LED that indicates the power state of the port and link
status.
