HP DL380z Gen8 Virtual Workstation - Manual (Page 38)

Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the system in a well-
ventilated, climate-controlled environment.
The maximum recommended ambient operating temperature (TMRA) for most server products is 35°
C (95° F). The temperature in the room where the rack is located must not exceed 35° C (95° F).
CAUTION: To reduce the risk of damage to the equipment when installing third-party options:
● Do not permit optional equipment to impede airflow around the server or to increase the internal
rack temperature beyond the maximum allowable limits.
● Do not exceed the manufacturer’s TMRA.
Power requirements
Installation of this equipment must comply with local and regional electrical regulations governing the
installation of information technology equipment by licensed electricians. This equipment is designed
to operate in installations covered by NFPA 70, 1999 Edition (National Electric Code) and NFPA-75,
1992 (code for Protection of Electronic Computer/Data Processing Equipment). For electrical power
ratings on options, refer to the product rating label or the user documentation supplied with that
option.
WARNING! To reduce the risk of personal injury, fire, or damage to the equipment, do not overload
the AC supply branch circuit that provides power to the rack. Consult the electrical authority having
jurisdiction over wiring and installation requirements of your facility.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a regulating
uninterruptible power supply. This device protects the hardware from damage caused by power
surges and voltage spikes and keeps the system in operation during a power failure.
When installing more than one server, you may need to use additional power distribution devices to
safely provide power to all devices. Observe the following guidelines:
● Balance the server power load between available AC supply branch circuits.
● Do not allow the overall system AC current load to exceed 80% of the branch circuit AC current
rating.
● Do not use common power outlet strips for this equipment.
● Provide a separate electrical circuit for the server.
Electrical grounding requirements
The server must be grounded properly for proper operation and safety. In the United States, you must
install the equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250,
as well as any local and regional building codes. In Canada, you must install the equipment in
accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other
countries, you must install the equipment in accordance with any regional or national electrical wiring
codes, such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7.
Furthermore, you must be sure that all power distribution devices used in the installation, such as
branch wiring and receptacles, are listed or certified grounding-type devices.
Because of the high ground-leakage currents associated with multiple servers connected to the same
power source, HP recommends the use of a PDU that is either permanently wired to the building’s
branch circuit or includes a nondetachable cord that is wired to an industrial-style plug. NEMA
