PoE Overview
The switch supports eight Power over Ethernet Plus (PoE+) ports and can supply up to 30W PoE+ (IEEE
802.3at) to each port up to its total maximum PoE power budget of 134W (model GC510P) or 195W (model
GC510PP) across all active PoE+ ports. The switch is backward compatible with PoE (IEEE 802.3af).
Supplied power is prioritized according to the port order, up to the total power budget of the device. Port 1
receives the highest PoE priority, while port 8 is relegated to the lowest PoE priority.
If the power requirements for attached devices exceed the total power budget of the switch, the PoE power
to the device on the highest-numbered active PoE+ port is disabled to make sure that the devices connected
to the higher-priority, lower-numbered PoE+ ports are supported first.
Although a device is listed as an 802.3at PoE+–powered or 802.3af PoE–powered device, it might not
require the maximum power limit that is specified by its IEEE standard. Many devices require less power,
allowing all eight PoE+ ports to be active simultaneously when the devices correctly report their PoE class
to the switch.
Using the local browser interface, you can control how PoE power is allocated across active PoE+ ports by
overriding the default or autodetected PoE power limits for individual PoE+ ports.
