PoE Usage (%)
This field displays the amount of power currently being supplied to connected PoE devices (PDs)
as a percentage of the total PoE power the Switch can supply.
When PoE usage reaches 100%, the Switch will shut down PDs one-by-one according to the PD
priority which you configured in
Basic Setting > PoE Setup
.
PoE Usage
Threshold (%)
This field displays the percentage of PoE usage. The Switch will generate a trap and/or a log
when the usage exceeds the specified threshold.
Consuming
Power (W)
This field displays the amount of power the Switch is currently supplying to the connected PoE-
enabled devices.
Allocated Power
(W)
This field displays the total amount of power the Switch (in classification mode) has reserved for
PoE after negotiating with the connected PoE device(s). It shows
NA
when the Switch is in
consumption mode.
Consuming Power (W)
can be less than or equal but not more than the
Allocated Power (W)
.
Remaining
Power (W)
This field displays the amount of power the Switch can still provide for PoE.
Note: The Switch must have at least 16 W of remaining power in order to supply
power to a PoE device, even if the PoE device needs less than 16W.
Port
This is the port index number.
State
This field shows which ports can receive power from the Switch. You can set this in
.
•
Disable
- The PD connected to this port cannot get power supply.
•
Enable
- The PD connected to this port can receive power.
Class
This shows the power classification of the PD. Each PD has a specified maximum power that fall
under one of the classes.
The
Class
is a number from 0 to 8, where each value represents the range of power that the
Switch provides to the PD. The power ranges in PoE standards are as follows.
•
Class 0
- default: 0.44 W to 15.4 W.
•
Class 1
- default: 0.44 W to 4 W.
•
Class 2
- default: 0.44 W to 7 W.
•
Class 3
- default: 0.44 W to 15.4 W.
•
Class 4
- default: 0.44 W to 30 W.
•
Class 5
- default: 0.44 W to 45 W.
•
Class 6
- default: 0.44 W to 60 W.
•
Class 7
- default: 0.44 W to 60 W.
•
Class 8
- default: 0.44 W to 60 W.
Note: You can set a limit on the maximum power the connected PD can use on a
port in
Basic Setting > PoE Setup > PoE Setup
.
PD Priority
When the total power requested by the PDs exceeds the total PoE power budget on the Switch,
you can set the PD priority to allow the Switch to provide power to ports with higher priority first.
•
Critical
has the highest priority.
•
High
has the Switch assign power to the port after all critical priority ports are served.
•
Low
has the Switch assign power to the port after all critical and high priority ports are
served.
Power-Up
This field displays the PoE standard the Switch uses to provide power on this port.
Consuming
Power (W)
This field displays the current amount of power consumed by the PD from the Switch on this port.
