Poe Overview - NETGEAR GC728X Hardware Installation Manual

Insight Managed 28-Port Gigabit Ethernet (PoE+) Smart Cloud Switch

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. 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 24 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 24 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 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.
