COMMAND USAGE
The switch automatically detects attached PoE devices by periodically
transmitting test voltages that over the Gigabit Ethernet copper-media
ports. When an IEEE 802.3af or 802.3at compatible device is plugged
into one of these ports, the powered device reflects the test voltage
back to the switch, which may then turn on the power to this device.
When the power inline compatible command is used, this switch can
detect IEEE 802.3af or 802.3at compliant devices and the more recent
802.3af non-compliant devices that also reflect the test voltages back
to the switch. It cannot detect other legacy devices that do not reflect
back the test voltages.
For legacy devices to be supported by this switch, they must be able to
accept power over the data pairs connected to the RJ-45 ports.

This command defines a power budget for the switch (i.e., the power
available to all switch ports). Use the no form to restore the default
setting.
