Chapter 6 Maximizing Avaya P460 Availability

Redundant Power Supplies

The Avaya P460 supports automatic Power Supply redundancy and load-sharing.

Power supply redundancy is activated according to the number of PSUs and I/O modules you have installed in the chassis.

Three PSUs are automatically configured in 2+1 redundancy mode.

If the installed power supplies can provide sufficient power for the switch, then an additional power supply is automatically configured to operate in Redundancy mode.

If the power budget requirement increases beyond the power available from the non-redundant power supplies, then the additional power supply reverts to regular mode.

In order to check whether power supply redundancy is operating, you can use the show environment power CLI command.

Note: The “Total Power drawn from the system” always includes the power reserved for two supervisor modules and the fan module.
