Configuring PoE redundancy

When PoE redundancy is enabled, PoE redundancy occurs automatically. The switch keeps track of power use and will not supply PoE power to additional PoE devices trying to connect if that results in the switch not having enough power in reserve for redundancy if one of the power supplies should fail.

Syntax:


[no] power-over-ethernet redundancy [n+1 | full]

Allows you to set the amount of power held in reserve for redundancy.

no

Means that all available power can be allocated to PDs.Default: No PoE redundancy enforced.

n+1

One of the power supplies is held in reserve for redundancy. If a single power supply fails, no powered devices are shut down.If power supplies with different ratings are used, the highest-rated power supply is held in reserve to ensure full redundancy.

full

Half of the available power supply is held in reserve for redundancy. If power supplies with different ratings are used, the highest-rated power supply is held in reserve to ensure full redundancy.

For more information about PoE redundancy and power supplies, see the PoE/PoE+ planning and implementation guide, available on the website at http://www.hpe.com/networking. Auto search the model number for your switch, For example, “Aruba switch 2930”, then select the device from the list, and click on Product manuals. Click on the “Setup and install — general” link under Manuals.
