PoE++ overview
The PoE++ ports on model GS110TUP (port 1–4) and model GS710TUP (port 1–8)
support IEEE 802.3bt Type 3 with 4-pair PoE. These models are also compatible with
PoE+ (IEEE 802.3at) and PoE (IEEE 802.3af) and can support non-PoE devices.
The maximum PoE power budget on the switch depends on the model:
•
Model GS110TUP. The maximum PoE power budget across all active PoE++ and
PoE+ ports is 240W.
The maximum PoE power that an individual PoE++ port can supply is 60W.
The maximum PoE power that an individual PoE+ port can supply is 30W.
•
Model GS710TUP. The maximum PoE power budget across all active PoE++ ports
is 480W.
The maximum PoE power that an individual PoE++ port can supply is 60W.
The PoE++ and PoE+ power supplied by the switch is prioritized in ascending port
order (from port 1 to port 8), with a total power budget of 240W (model GS110TUP) or
480W (model GS710TUP) across all active PoE++ and PoE+ ports.
The following table shows the standard power ranges, calculated with the maximum
cable length of 328 feet (100 meters). If a device receives insufficient PoE power from
the switch, consider using a shorter cable.

The switch supports uninterrupted PoE, which enables the switch to provide PoE power
while rebooting. By default, the uninterrupted PoE feature is disabled, causing the switch
to stop providing PoE power while it is rebooting. If you enable the uninterrupted PoE
feature, the switch continues to provide PoE power to any attached PDs while the switch
is rebooting, even if it is rebooting after a regular firmware update.
