Global Configuration
Command Usage
Setting a maximum power budget for the switch enables power to be centrally
managed, preventing overload conditions at the power source.
If the power demand from devices connected to the switch exceeds the power
budget setting, the switch uses port power priority settings to limit the supplied
power.

power inline priority (4-189)

power inline compatible

This command allows the switch to detect and provide power to powered devices
that were designed prior to the IEEE 802.3af PoE standard. Use the no form to
disable this feature.
Syntax
[no] power inline compatible
Default Setting
Disabled
Command Mode
Global Configuration
Command Usage
The switch automatically detects attached PoE devices by periodically
transmitting test voltages over the RJ-45 ports. When an 802.3af 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
802.3af 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.
