User's Manual of GS-5220 Ultra PoE & PoE+ Series

Profile4
Allows user to select IEEE802.3at/802.3af/Ultra PoE compatibility mode. The
default value is UPoE mode.
Indicates the power inline mode. Possible profiles are:

End-Span: Pins 1–2 (pair #2 in both T568A and T568B) form one side
of the DC supply and pins 3–6 (pair #3 in both T568A and T568B)
provide the return

Mid-Span: Pins 4–5 (pair #1 in both T568A and T568B) form one side
of the DC supply and pins 7–8 (pair #4 in both T568A and T568B)
provide the return

UPoE: Pins 1–2 (pair #2 in both T568A and T568B) form one side of
the DC supply and pins 3–6 (pair #3 in both T568A and T568B)
provide the return. Pins 4–5 (pair #1 in both T568A and T568B) form
one side of the DC supply and pins 7–8 (pair #4 in both T568A and
T568B) provide the return.
The Priority represents PoE ports priority. There are three levels of power priority
named Low, High and Critical.
The priority is used in case the total power consumption is over the total power
budget. In this case, the port with the lowest priority will be turned off, and power
for the port of higher priority will be offered.
It can limit the port PoE supply wattage. Per port maximum value must be less
than 72 watts(GS-5220-16UP4S2X/R, GS-5220-24UP4X/R and
GS-5220-24UPL4X/R) and 36 watts(GS-5220-24P4X/R and
GS-5220-24PL4X/R); total ports values must be less than the Power
Reservation value. Once power overload is detected, the port will automatically
shut down and continue to be in detection mode until Pad's power consumption
is lower than the power limit value.
