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
64W (model GC108P) or 126W (model GC108PP) across all active PoE+ ports. You can
increase the power budget of model GC108P to 126W by purchasing and connecting
the NETGEAR optional power adapter model EPS130W.
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.
