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 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 NFP
A-75, 1992 (code
for Protection of Electronic Computer/Data Processing Equipment). For electrical power ratings on options,
see the product rating label or the user documentation supplied with that option.
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 might have 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 NFP
A 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.
