NETGEAR M4350-24F4V 24-Port 10G SFP+ Managed AV Network Switch - Manual (Page 172)

• Pre-802.3bt (PoE++ models only): The port supports Class 4 devices that use
4-pair PoE (4PPoE) to receive power higher than 30W but that are not compliant
with IEEE 802.3bt. The port also supports the IEEE 802.3at and IEEE 802.3af
modes.
• 802.3bt-Type3 (PoE++ models only): The port supports the IEEE 802.3bt Type
3 mode, the IEEE 802.3at mode, and the IEEE 802.3af mode.
• 802.3bt (PoE++ models only): The port is powered in the IEEE 802.3bt mode
and is backward compatible with IEEE 802.3at and IEEE 802.3af. In this mode, if
the switch detects that the attached PD requests more power than IEEE 802.3at
but is not an IEEE 802.3bt device, the PD does not receive power from the switch.
11. From the Power Limit Type menu, select how the port controls the maximum power
that it can deliver:
• None: For PoE+ (802.3at) ports, the port draws up to Class 0 maximum power
in low power mode. In high power mode, the following applies:
- PoE+ (802.3at) ports: The port draws up to Class 4 maximum power.
- PoE++ (802.3bt) ports (PoE++ models only): The port draws up to Class 8
maximum power.
• Class: The port power limit is equal to the class of the attached PD. This is the
default setting. The upper limit is the power that a port can deliver to a PD. The
class is detected based on the PD that is attached to the port, and the following
applies:
- PoE+ (802.3at) ports: Possible values are from Class 0 to Class 4.
- PoE++ (802.3bt) ports (PoE++ models only): Possible values are from Class
0 to Class 8.
• User: The port power limit is equal to the value that is specified in the Power
Limit (W) field.
NOTE: If a PD does not report its class correctly, use of these options can
preserve additional PoE power by preventing the switch from delivering
more power than the PD requires. However, depending on which option
you select, a PD that does not report its class correctly might not power up
at all.
12. In the Power Limit (W) field, enter the maximum power (in W) that the port can
deliver.
