Enable – Enables PoE capability on the
port. By default, power is enabled on
all ports, allowing them to supply
Power over Ethernet to any connected
device.
Disable – Disables PoE capability on
the port
Option Description
Priority When the available power budget (180
watts total power, with 18 watts guard
band) is exceeded, the Switch stops sup-
plying Power over Ethernet to lower pri-
ority ports. Set the PoE priority for the
port by selecting one of the following
options:
Low (least important)
■
High (default)
■
Critical (most important)
■
For ports with the same priority, ports
connected to the lowest physical port
number will have priority over those
connected to higher port numbers. For
example, port 3 will have a higher prior-
ity than port 5, providing they both
share the same power priority weight-
ing. A critical device on port 24 will have
a higher priority than a low priority
device on port 1.
For more information on planning for
and managing PoE, refer to
Power Budget"
Power Limit Sets the maximum power that is allo-
cated for the connected PoE device.
Available options include:
15400 (default)
■
7000
■
4000

Figures are in milliwatts.
Power Used If a PoE device is connected to the port,
shows how much power it is using. Fig-
ures are in decivolts (dV). To get the
actual voltage, divide the number by 10.
