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, 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, 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 off 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.
CAUTION: To prevent improper cooling and thermal damage, do not operate the server with the media bay blank,
chassis cover, or the front bezel removed.
CAUTION: To prevent damage to electrical components, properly ground the server before beginning any
installation procedure. Improper grounding can cause electrostatic discharge.
CAUTION: To avoid data loss, Hewlett Packard Enterprise recommends that you back up all server data before
installing or removing a hardware option, or performing a server maintenance or troubleshooting procedure.
