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 C221, 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.
Server warnings and cautions
WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment, disconnect the power
cord to remove power from the server. Pressing the Power On/Standby button does not shut
o system power
completely. Portions of the power supply and some internal circuitry remain active until AC power is removed.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system
components to cool before touching them.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a regulating UPS. This
device protects the hardware from damage caused by power surges and voltage spikes and keeps the server in
operation during a power failure.
