Operation Manual

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 server, or damage to the equipment, disconnect
the power cord to remove power from the . Pressing the Power On/Standby button does not shut off
system power completely. Portions of the power supply and some internal circuitry remain active
until AC power is removed.
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.
CAUTION:
Do not operate the server for long periods with the access open or removed. Operating the server in
this manner results in improper airflow and improper cooling that can lead to thermal damage.
