Enable Inline-Power Legacy - Extreme Networks ExtremeWare XOS Command Reference Manual

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
Power Over Ethernet Commands

enable inline-power legacy

enable inline-power legacy
Description
Enables the non-standard (or capacitance) power detection mechanism for the stand-alone switch.
Syntax Description
This command has no arguments or variables
Default
Disable.
Usage Guidelines
This command disables the non-standard power-detection mechanism on the switch. Legacy PDs do not
conform to the IEEE 802.3af standard but may be detected by the switch through a capacitance
measurement.
However, measuring the power through capacitance is used only if this parameter is enabled and after
an unsuccessful attempt to discover the PD using the standard resistance measurement method. The
default for legacy is disabled.
CAUTION
A normal (non-PoE) device may have a capacitance signature that causes the device to be detected as a legacy PoE
device (and have power supplied), potentially causing damage to the device.
Example
The following command enables capacitance detection of PDs on the switch:
enable inline-power legacy
History
This command was first available in ExtremeWare XOS 11.5.
Platform Availability
This command is available on the Summit X450e-24p switch.
