PoE considerations for switches that support
PoE
A switch that supports Power over Ethernet (PoE) prioritizes the PoE power that it supplies
in ascending port order (that is, from the lowest-numbered port to the highest-numbered
port), up to its total power budget. If the power requirements for the attached powered
devices (PDs) exceed the total power budget of the switch, the PD on the
highest-numbered port is disabled to make sure that the PDs that are connected to the
higher-priority, lower numbered ports are supported first.
Just because a PD is listed as an 802.3at PoE powered device does not necessarily mean
that it requires the maximum power limit of the specification. Many PDs require less
power, allowing all PoE ports to be active simultaneously.
The following table describes the PoE classes and the PoE power that a switch allocates.

Manage the PoE ports
You can turn the port on the switch on and off by using the device UI.
To power cycle the PoE ports through the device UI:
1.
Open a web browser from a computer that is connected to the same network as the
switch, or connected directly to the switch through an Ethernet cable.
2. Enter the IP address that is assigned to the switch.
A login window opens.
