Power quality

Most HP products are designed to operate over a wide range of voltages and frequencies. The products are tested and shown to comply with certain EMC Specifications. However, damage can occur if these ranges are exceeded. Severe electrical disturbances can exceed the design specifications of the equipment.

Factors affecting power quality

Common factors that affect power quality include the following:

•Electrical storms

•Utility service brownouts or sags

•Faults in the power generation equipment

•Large inductive loads, such as motors and welders

•Load fluctuations occurring within the facility distribution system

•Loose connections or other faults in the distribution system wiring

Power system protection

HP products can be protected from the sources of many of these electrical disturbances by using the following:

•A dedicated power distribution system

•Power conditioning equipment

•Over- and under-voltage protection and detection circuits

•Lightning arresters on power cables to protect equipment against electrical storms

The power distribution system is designed to provide immunity to power interruptions. However, testing cannot conclusively rule out loss of service. Use the following guidelines to provide the best possible performance of power distribution systems for HP computer equipment:

•Dedicated power source—Isolates the power distribution system from other circuits in the facility.

•Online uninterruptible power supply (UPS)—Keeps input voltage to devices constant and should be considered if outages of one-half cycle or more are common.

•Auto-start generators–provide backup power to the UPS.

•Missing-phase and low-voltage detectors—initiate a transfer of the UPS to generator power when a severe power interruption occurs. For peripheral equipment, these devices are recommended but optional.

For each situation, refer to qualified contractors or consultants.

Power considerations

Power is best managed within the rack by the use of one or more rack-mounted PDUs. Depending on the configuration, it may be necessary or preferable to use multiple PDUs to connect all devices inside the rack.
