The Power System

Overview

Two power supplies are required to operate a fully-loaded P580 or P882 chassis. You can install a third power supply for backup if one of the other two fails.

Features of the power system include:

• Load sharing by the installed power supplies.
• Power supplies can be warm swapped. (Before removing a power supply, you must turn it off and unplug it; however, the other power supplies can remain turned on).
• Both AC and DC power supplies are supported.
• Static power allocation or dynamic power allocation if insufficient power is available for all modules in the chassis.
