VLAN Isolation Feature
The 802.3at PoE+ Switch has one feature called VLAN function. When switching
the mode to the
“VLAN”
position, port 1 to port 8/16/24 wouldn’t able to
communicate with each other.

2.3.2 Budget Control
Due to the power allocation strategy of PSE, when the residual power of PoE is
too large, the power distribution of the port can be increased as much as possible
by increasing the power trimming of the PSE, so that the utilization of the PSE
power supply can be improved. There are four levels of budget control named
Unchanged (default), Add 5% PB, Add 10% PB
and
Add 15% PB
.
Note
1. The default PoE budget is 120W/300W in unchanged mode. If
you hope to have a full load of over 120W/300W, please select
Add 5% PB, Add 10% PB and Add 15% PB.
2. In order to make sure the PSE power supply is not overloaded for a long
time, please try to ensure that TP is less than PB
.
