Power Requirements; Electrical Grounding Requirements; Server Warnings And Cautions - HP HPE ProLiant ML30 Gen9 User Manual

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 NFPA-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 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.

Server warnings and cautions

WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and the
internal system components to cool before touching them.
WARNING: To reduce the risk of personal injury, electric shock, or damage to the equipment,
remove the power cord to remove power from the server. The front panel Power On/Standby
button does not completely shut off system power. Portions of the power supply and some
internal circuitry remain active until AC power is removed.
