Fixed Cord PDUs and Extension Bars have a unique architecture designed specifically for 1U fixed rail servers i.e. DL 360 and DL 320). This new design consists of short, attached cords on the extension bar, resulting in significantly less cable hanging in the back of the rack, improved air flow through the rack and one less point of cable disconnect. Each Fixed Cord Extension Bar connects to the family of PDU cores already available from HP. Two configurations are available: (1) the Fixed Cord Extension Bars contains two extension bars (sticks) and all mounting brackets and hardware, and (2) the Fixed Cord PDU contains four extension bars plus a modular PDU core. Like all existing HP PDUs, the fixed cord PDU also offers you the flexibility to easily mount your units in several different locations within the rack, without having to sacrifice valuable rack U-space.
