If you set the PoE maximum value to less than what the PD requires, a fault occurs, as shown in
power value set too low for the PD
on page 112.

‘Fault’ appears when the PoE power value is set too low.
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.

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