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.
Example
Related Commands
power inline priority (4-163)
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

Global Configuration
Command Usage
• The switch automatically detects attached PoE devices by periodically
transmitting test voltages that over the 10/100BASE-TX 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 1000BASE-T ports.
