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 (UPS). 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 percent 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.

in various system configurations, refer to the HP Enterprise Configurator website
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
