Power Over Ethernet Commands
ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
ExtremeWare XOS 11.5 Command Reference Guide
522
disable inline-power legacy slot
disable inline-power legacy slot <slot>
Description
Disables the non-standard (or capacitance) power detection mechanism for the specified slot.
Syntax Description
Default
Disable.
Usage Guidelines
This command disables the non-standard power-detection mechanism on the switch or specified slot.
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.
The reason legacy detection is configurable is that it is possible for a normal (non-PoE) device to have a
capacitance signature that causes the device to be detected as a legacy PoE device and have power
delivered to it, potentially causing damage to the device.
Example
The following command disables capacitance detection of PDs on slot 3 of a modular switch:
disable inline-power legacy slot 3
History
This command was first available in ExtremeWare XOS 11.1.
Platform Availability
This command is available on the G48P and G48Pe modules installed in the BlackDiamond 8800 series
switch.
slot
Disables non-standard power detection for specified slot on a modular switch.
