User Manual

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.
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, Hewlett Packard Enterprise 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 locking-style plugs or those complying with IEC 60309 are considered suitable for this purpose.
Using common power outlet strips for the server is not recommended.
