Remote management via a web engine is built in to the HP iPDU and even provides power-cycle ability of individual outlets or pairs of outlets. HP is the first to incorporate Intelligent Power Discovery which, when combined with HP's line of Platinum level high efficiency power supplies, allows the HP iPDU to communicate with the attached servers. The iPDU relays information for the automatic mapping of the power topology inside a rack - greatly reducing the risk of human errors that can cause power outages. These rack-mount PDUs provide both single-phase and three-phase monitored power, as well as full-rack power utility ranging from 4.9kVA up to 22kVA and up to 30 outlets.
