PoE for Pre-802.3af-standard PDs

By default, all ProCurve PoE switches support 802.3af-standard PDs. In
addition, the switches covered in this guide have the ability to supply power
to pre-802.3af-standard devices, such as legacy (non-standard) IP phones.
When the switch is in legacy detection mode, the detection signature range is
expanded beyond the IEEE specification. This allows non-compliant devices
to be powered.
For a current listing of PDs supported by this feature, visit the ProCurve
Networking website at www.procurve.com. Click on Technical support,
and then on FAQs, and then select the switch model.
How to enable/disable PoE for pre-802.3af-standard powered devices.
PoE for pre-802.3af-standard powered devices is disabled by default.
Syntax: [no] power pre-std-detect
The above command enables PoE for pre-802.3af-standard
powered devices. The no form of the command sequence
disables PoE for pre-802.3af-standard powered devices.
(Default: Disabled)
To enable this feature, you would enter:
ProCurve(config)# power pre-std-detect
PoE for pre-802.3af-standard powered devices can be enabled or disabled only
from the switch's CLI. This feature cannot be enabled or disabled through
either the switch's menu or web browser interfaces.
Executing the show power-management command lists the system power
status as follows:
: 406 W
: 75 W +/- 6 W
