Power management is a way to limit the total available power to be used for Power over Ethernet (PoE) ports. Without power management, the total amount of power that the power supply units (PSU) are able to provide is used. Power management can be used to create power redundancies. For example, if a system has 2 1050W PSUs, the feature can set the total available power to be 800W for PoE. With this configuration, 1 PSU is sufficient to power the system and the unused PSU acts as a backup source, thus giving the system a 1+1 redundancy.
