PoE Ports
The RUGGEDCOM RS416P supports up to four 10/100Base-TX Power over Ethernet (POE) ports powered by
an external power supply. Each port complies with the IEEE 802.3af standard and features auto-sensing and
automatic power off when cables are removed.
PoE ports can be located in sets of two in slots 5 and 6.
The total allowable power budget for all ports is 60 W. If the external power supply is less than 60 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 User Guide for the RUGGEDCOM RS416P.
For information about connecting the external power supply, refer to Section 2.6.2, “Connecting External PoE
Power” .
