PoE Overview
Model GC728XP supports 24 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 390W across all active PoE+ ports.
Model GC752XP supports 48 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 505W across all active PoE+ ports.
These models are backward compatible with PoE (IEEE 802.3af).
By default, the supplied power is prioritized according to the port order, up to the total power budget of the
device. For model GC728XP, port 1 receives the highest PoE priority, while port 24 is relegated to the lowest
PoE priority. For model GC752XP, port 1 receives the highest PoE priority, while port 48 is relegated to the
lowest PoE priority.
For both models, you can override the default PoE power settings, prioritize the ports
in any order, and specify the exact power that is allotted to each port (see below).
Note
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 24 (model GC728XP) or 48 (model GC752XP) PoE+ ports to be active simultaneously when
the devices correctly report their PoE class to the switch.
Using the advanced PoE controls in the NETGEAR Insight mobile app and Insight Cloud portal, 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.You can also specify the exact PoE power limit per port from 3.0W
to 30.0W.
