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.
