1) Please do not modify the input power. If the setting value is more than the actual power of
the built-in power transformer, there will be a risk of overloading the unit and burning it out.
if the setting value is less than the actual power for the built-in power supply, it can not be
fully allocated out of the ports.
2) Each port on the 8808F switch will provide a maximum output power of 30W even if the
user sets it beyond 30W, it will still only output a max of 30W.

DESCRIPTION
POWER PROVIDED
Determined by the built-in power supply module and can not exceed the
maximum power supply.
OVERLOAD LIMIT
Built-in power supply allows an overload rate. S
etting ranges from 0% ~
10%
Default: 5%
if the actual output power is overloaded, it will cause the
built-in power supply to shut down power to ports with lower priority.
RESERVED RATE
Reservation power can not be used for distribution, but can be used for PD
power consumption caused by overload change.
The default is 15% of the
total power.
The larger the number is, the smaller the risk of system
overload. So as the usable power for distribution and PD quantity become
less, the more the amount of PD access and greater the risk of system
overload.
