PoE concepts
Depending on the model, the switch includes eight PoE plus (PoE+) ports.
The following table shows the capacity for each model.
Table 75. PoE capacities for each model
Model Maximum PoE
Power
Per Port
Maximum Power Budget Across All Active PoE+ Ports
GC108P 30W PoE+ (IEEE
802.3at)
64W
GC108PP 30W PoE+ (IEEE
802.3at)
126W
By default, supplied power is prioritized in ascending port order, up to the total power budget
of the device. If the power requirements for the attached devices exceed the total power
budget of the switch, the power to the device on the highest-numbered PoE+ port is disabled
to make sure that the devices connected to the higher-priority, lower-numbered PoE+ ports
are supported first.
It is important to note that 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.
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.
Device class power requirements
PoE and PoE+ use Ethernet cables to supply power to PoE-capable devices on the network,
such as WiFi access points, IP cameras, VoIP phones, and switches. The switch is compliant
with the IEEE 802.3at standard (PoE+) and backward compatible with the IEEE 802.3af
standard (PoE). The switch can pass power through to any powered device (PD) that
supports these standards. PoE and PoE+ let you power such devices without the need for a
separate power supply.
The switch supports a Plug-and-Play process by which it detects the type of device that is
connected to one of its PoE+ ports and whether that device needs power and how much so
that the switch can provide the correct power the device.
During the Plug-and-Play process, the connected device can provide its Class response to
the switch in many ways, depending on how the vendor programmed the device.
The following table shows the device classes for PoE+ devices adhering to the IEEE 802.3at
standard.
The device classes for PoE devices adhering to the IEEE 802.3af standard are
identical with the exception that Device Class 4 is not supported.
Note: By purchasing and connecting the NETGEAR optional power adapter
model EPS130W, you can upgrade the PoE power budget to 126W.
