PoE Port Settings
The EnGenius Layer 2 PoE+ Switches supports Power
over Ethernet (PoE) as dened by the IEEE 802.3af and
802.3at. All ports can support PoE up to 30W. Ports 1-24
can supply about 48 VDC power to Powered Devices (PDs)
over standard UTP Ethernet cables. The Switch follows the
standard PSE (Power Sourcing Equipment) pinout, whereby
power is sent out over pins 1, 2, 3 and 6.
EGS5212FP: Ports 1-8 supports both IEEE802.3 af and at. The
maximum power budget is 130 Watts.
EGS7228P: Ports 1-24 supports both IEEE802.3 af and at. The
maximum power budget is 185 Watts.
EGS7228FP: Ports 1-24 supports both IEEE802.3 af and at. The
maximum power budget is 370 Watts and 720 Watts when you are
using the EnGenius RPS370 external redundant power supply.
EGS7252FP: Ports 1-48 supports both IEEE802.3 af and at. The
maximum power budget is 740 Watts.

PoE parameters are assigned to the powered device that is
connected to the selected port.
State:
• Enable – Enables the Device Discovery protocol and provides
power to the device using the PoE module. The Device Discovery
Protocol lets the device discover powered devices attached to
deviceinterfacesandlearnstheirclassication.
• Disable – Disables the Device Discovery protocol and halts
the power supply delivering power to the device using the PoE
module.

• Low – Sets the PoE priority level as low.
• Medium – Sets the PoE priority level as medium.
• High – Sets the PoE priority level as high.
• Critical – Sets the PoE priority level as critical.
