Parameter
Description
Power
provided
Determined by built-in power supply module and can not
exceed maximum power supply.
Overload limit
Built
-
in
power supply allows overload rate
.
Setting
range
0%
～
10%, default 5%, if actual output power is overlarge, it will
cause
built
-
in
power supply exceeds the set value, the
system will power off ports with lower priority.
Reserved rate
Reservation power
can not be used for distribution, but can be
used for PD consumption caused by overload change, The
default is 15% of the total power.
The larger this number
,
the
smaller the risk of system overload
,
So
the usable power
for
distribution and PD quantity
become
less
;
on the contrary
,
the more the number of PD access, the greater risk of system
overload.
Consumed
Actual output total power.
Remaining
Means power that could be used for redistribution. surplus=
input - actual output - reservation. Please note that when insert
a new PD equipment,
the power will be distributed based on
the detected PD power level instead of the actual power of
inserted PD , for example : when surplus power is 20W, the
system still can not distribute power nor supply power if insert
power level of PD is 25.5W and the actual power only requires
10W.
Reserved
Used for PD consumption with overload changes, It stems from
the set menu “input power rate * reserve power”.
Provided
T
otal power for system setting,
the set menu “input
power”.
It stems from
Priority
There have three level of “low”, “middle”, “high” for port power
supply priority. when the system is overloaded, the power
supply of the port with low priority will be turned off firstly.
Power limit
Set
the
output
power
limit for single port., the port will power
off when actual output power exceeds limit.

the port POE
Setting
Sett port priority, maximum power consumption.
(1) Please do not modify the input power, if the setting value is more
than the actual power of the built-in power, there will be a risk of
overload burning. If the setting value is less than the actual power for
the built-in power supply, it can not be fully allocated out.
(2) Each port of the product is to provide maximum output power of
30W, if user setting exceeds 30W, 30W is still the maximum power
output only.
