Poe++ And Poe+ Overview - NETGEAR MS108EUP Hardware Installation Manual

8-port Ultra60 PoE++ Multi-Gigabit (2.5G) Ethernet Plus Switch MS108EUP

PoE++ and PoE+ overview

The PoE++ ports (1–4) support IEEE 802.3bt. These ports are also compatible with PoE+
(IEEE 802.3at) and PoE (IEEE 802.3af) and can support non-PoE devices. The maximum
PoE power that an individual PoE++ port can supply is 60W.
The PoE+ ports (5–8) support IEEE 802.3at. These ports are also compatible with PoE
(IEEE 802.3af) and can support non-PoE devices. The maximum PoE power that an
individual PoE+ port can supply is 30W.
The maximum PoE power budget for the switch across all active PoE++ and PoE+ ports
is 230W.
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 230W 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.
