In domestic installations, install approved receptacles before the HP equipment arrives.
See the appropriate installation guide for installation procedures.
Acclimatization
IMPORTANT:
of the product to equalize to the temperature and humidity of the installation facility. A minimum
of 10°C (50°F) to one hour of temperature difference between the shipping/receiving facility and
installation facility is required.
The physical size of the product determines the time period required to acclimate to the
surrounding controlled computer room. For example: A 2m cabinet populated with racked
equipment or a large, preconfigured server system may require an overnight period. The
temperature of a small desktop printer would equalize sooner at the 10°C (50°F) per one hour
rate.
Wiring Connections
Expansion and contraction rates vary among different metals. Therefore, the integrity of an
electrical connection depends on the restraining force applied. Connections that are too tight
compress or deform the hardware and cause it to weaken. This usually leads to high impedance,
preventing circuit breakers from tripping when needed. High impedance can also contribute to
a buildup of high-frequency noise.
CAUTION:
serious problems, such as erratic equipment operation. A high-impedance connection overheats
and sometimes causes fire or high temperatures that can destroy hard-to-replace components,
such as distribution panels or system bus bars.
Wiring connections must be properly torqued. Many equipment manufacturers specify the proper
connection torque values for their hardware. See the safety requirements provided by your wire
manufacturer.
Ground connections must be made only on a conductive, nonpainted surface. When equipment
vibration is present, lock washers must be used on all connections to prevent connection hardware
from working loose.
Data Communications Cables
Power transformers create high-energy fields in the form of electromagnetic interference (EMI).
Heavy foot traffic can create electrostatic discharge (ESD) which can damage electronic
components. Route data communications cables away from these areas and use shielded data
communications cables that meet approved industry standards to reduce the effects of external
energy fields.

Synopsis
Air Quality
Proper computer room preparation improves air quality. It provides a return on investment by
making a system more stable and by decreasing unexpected downtime. HP recommends putting
appropriate effort into maximizing electrical and air-conditioning efficiency to ensure higher
reliability to meet business needs.
