Configuring PoE Redundancy (Chassis Switches Only)
When PoE redundancy is enabled, PoE redundancy occurs automatically. The
switch keeps track of power use and won’t 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.
The no option 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.
