Electrical Grounding Requirements
WARNING: This equipment is designed for connection to a grounded AC outlet.
The grounding type plug is an important safety feature. To reduce risk of
electrical shock or damage to your equipment, do not disable the grounding
feature on the plug.
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, the equipment must be installed
in accordance with Canadian Standards Association, CSA C22.1, Canadian
Electrical Code. In all other countries, the installation must follow any
regional or national electrical wiring codes, such as the International
Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore,
you must ensure 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, Compaq recommends the use of a power
distribution unit (PDU) that is either permanently wired to the building branch
circuit or includes a nondetachable cord wired to an industrial-style plug.
NEMA locking-style plugs or those complying with IEC 60309 are considered
suitable for this purpose. Compaq does not recommend using common power
outlet strips for this equipment.
Temperature Requirements
To ensure continued safe and reliable equipment operation, install or locate the
system in a well-ventilated, climate controlled environment. The maximum
recommended ambient operating temperature (TMRA) for most Compaq
server products is 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 servers or
to increase the internal rack temperature beyond the maximum allowable
limits.
■ Do not exceed the manufacturer’s TMRA.
