The main objective of this feature is to prevent modular systems from being shut down due to insufficient power by powering off cards if there is not enough power in the system at card startup.

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.

This feature is used to save power by turning off front panel LEDs when they are not needed. After this feature is enabled, LEDs will be turned off after 1 hour from the time of system boots up or feature enabled. Transceiver insertion/removal or USB insertion will cause the LEDs to turn on for 1 hour.

Pseudo load sharing is a load sharing scheme for two power supply units (PSU) that do not have integrated load sharing. With pseudo load sharing, the system power is divided into two power domains, each with one PSU that is connected to a port group consisting of half of the system's Power over Ethernet (PoE) ports. When both PSUs are active, the power domains are independent and each PSU can only provide power to ports within the same power domain. Each port group can consume up to the maximum available power of the PSU in the same power domain. When only one PSU is active, the power switch between the two power domains can route power from the active PSU to all ports on the system.
