HP ProVision / ProCurve switches support some old pre-standard PoE equipment like the Cisco 7960G phone. The pre-standard PoE is disabled by default. Enable it with the following global configuration command.
power pre-std-detect ports 1-12
- If you want to apply the command to all ports, exclude the “ports” part of the command
- show power brief
- View the pre-std-detect settings along with other PoE port status with the “show power brief” command. You can also use the “show run” command to view the configuration commands currently applied to your switch.
This feature is mentioned in an old HP 2610 Switch FAQ and also in the downloadable “HP Power over Ethernet Planning and Implementation Guide” for many switches.
