NETGEAR AV Line M4250 GSM4210PX 8-Port Gigabit PoE+ Compliant Managed AV Switch with SFP (220W) - Manual (Page 140)

• To configure a single port, select the check box associated with the port, or type
the port number in the Go To Interface field and click the Go button.
• To configure multiple ports with the same settings, select the check box associated
with each port.
• To configure all ports with the same settings, select the check box in the heading
row.
7. From the Port Power menu, select the administrative PoE mode of the port:
• Enable: The port’s capacity to deliver power is enabled. This is the default setting.
• Disable: The port’s capacity to deliver power is disabled.
8. From the Port Priority menu, select the priority for the port in relation to other ports
if the total power that the switch is capable of delivering exceeds the total power
budget:
• Low: Low priority. This is the default setting.
• Medium: Medium priority.
• High: High priority.
• Critical: Critical priority.
The port priority determines which ports can still deliver power after the total power
delivered by the switch exceeds the total power budget. (In such a situation, the
switch might not be able to deliver power to all connected devices.) If the same
priority applies to two ports, the lower-numbered port receives higher priority.
9. From the Power Mode menu, select the PoE mode that the port must function in:
• 802.3af: The port is powered in and limited to the IEEE 802.3af mode. A PD that
requires IEEE 802.3at does not receive power if the port functions in IEEE 802.3af
mode.
• Legacy: The port is powered using high-inrush current, which is used by legacy
PDs that require more than 15W to power up.
• Pre-802.3at: The port is initially powered in the IEEE 802.3af mode and, before
75 msec pass, is switched to the high power IEEE 802.3at mode. Select this mode
if the PD does not perform Layer 2 classification or if the switch performs
2-event Layer 1 classification.
• 802.3at: The port is powered in the IEEE 802.3at mode and is backward
compatible with IEEE 802.3af. The 802.3at mode is the default mode. In this mode,
if the switch detects that the attached PD requests more power than IEEE 802.3af
but is not an IEEE 802.3at Class 4 device, the PD does not receive power from the
switch.
• Pre-802.3bt: 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.
