Ì Six mounting screws The Compaq Power Distribution Unit manages power distribution within Compaq rack cabinets by providing 12 AC receptacles at one single input power cord for rack-mountable devices. Total electrical current (measured in amperes and referred to as an electrical load) generated from all connected devices can often consume more power than typically provided from a standard prong 15A commercial wall outlet.

This high voltage Power Distribution Unit provides up to a 30-ampere capacity of alternating current load at 208 volts. This new Compaq PDU is the source to accommodate more powerful loads, and will support twice the load segments of the 16A model and is equipped with four circuit breakers providing additional protection.

208-240V for rack-mountable servers, and protects to 50,000A per unit, supporting electrical power distribution requirements of the Compaq rack environment. This High Voltage PDU utilizes IEC320 (C-10) output connectors, whereas the input is provided by a 16A IEC320 (C19) inlet connector to link the AC source to the rack cabinet.

50,000A of surge current clamping at 180 volts. This PDU model provides up to 24A of alternating current capacity to support demanding power distribution requirements of the Compaq rack environment. The Low Voltage PDU utilizes NEMA 5-15R output receptacles that are similar to standard wall outlet connections.

The Compaq Power Distribution Unit is “zero-U”, requiring no front-panel rack-mounting space, and easily installs into the wall of Compaq 42U, 36U, and 22U rack cabinets. The Compaq PDU is designed for mounting between the frame members of a rack to preserve interior and front panel rack space for business-critical servers and other equipment.
Page 8: Single Point Of Connection
Compaq Power Distribution Unit Information Guide Single point of connection The Compaq Power Distribution Unit connects up to 12 devices to a single outside connection, eliminating multiple power cords connected to AC receptacles outside the equipment rack. This single point of connection simplifies cable management and routing to minimize the risk of inadvertent plug removal.

Advanced Power Distribution Unit Application Tiered PDU Configuration The Compaq Power Distribution Unit can also be used in conjunction with a second Compaq PDU to provide an additional twelve power connections with continued power surge protection. Even when two Power Distribution Units are installed into a rack environment, the “zero-U”...
Page 11: Power Supply Redundancy
Compaq Power Distribution Unit Information Guide Power Supply Redundancy Along with the addition of extra outlet availability, a second Power Distribution Unit coupled with a second Uninterruptible Power System will create a redundant power supply to improve reliability. Simply, install a second UPS into the rack environment to ensure enhanced power protection and connect each PDU to their own individual UPS.

R3000 UPS, and the 16A High Voltage PDU is specifically accommodated by the R3000H model UPS. On the R3000 UPS models, Compaq provides a high current outlet that is part of the third load segment of the UPS. By plugging the Compaq Power Distribution Unit into this high current outlet, an additional twelve outlets are added to the UPS, which can be managed as part of load segment three.
Page 13: Questions And Answers
A Power Distribution Unit, or PDU, is a device that distributes energy to multiple external devices in increments to suit individual power requirements. Q My system is running a full rack configuration. How can I add a Compaq Power Distribution Unit? The Compaq Power Distribution Unit has an exclusive “...
Page 14 Q How do I install a Power Distribution Unit? Refer to the installation documentation that accompanied the PDU. Q Is it possible to have a power back-up supply when utilizing a Compaq Power Distribution Unit? Yes. Simply add either another 16A High Voltage PDU or another Low Voltage PDU with a second Uninterruptible Power System to the rack configuration.
