CAUTION:CAUTION:
Protect the storage 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 storage server in operation
during a power failure.
When installing more than one storage server, you might need to use additional power distribution devices to safely provide power to all
devices. Observe the following guidelines:
Balance the 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 storage server.
For more information on the hot-plug power supply and calculators to determine power consumption in various system configurations, see
the Hewlett Packard Enterprise website (http://www.hpe.com/info/poweradvisor/onlinehttp://www.hpe.com/info/poweradvisor/online).
Electrical grounding requirementsElectrical grounding requirements
The storage 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 regions,
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 storage servers connected to the same power source, Hewlett
Packard Enterprise recommends the use of a PDU that is either permanently wired to the branch circuit of the building or includes a
nondetachable cord that is wired to an industrial-style plug. NEMA locking-style plugs or plugs complying with IEC 60309 are considered
suitable for this purpose. Using common power outlet strips for the storage server is not recommended.
Electrostatic dischargeElectrostatic discharge
Be aware of the precautions you must follow when setting up the system or handling components. A discharge of static electricity from a
finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy
of the system or component.
To prevent electrostatic damage:
Avoid hand contact by transporting and storing products in static-safe containers.
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
Place parts on a grounded surface before removing them from their containers.
Avoid touching pins, leads, or circuitry.
Always be properly grounded when touching a static-sensitive component or assembly. Use one or more of the following methods when
handling or installing electrostatic-sensitive parts:
Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a
minimum of 1 megohm ±10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive
floors or dissipating floor mats.
Use conductive field service tools.
Use a portable field service kit with a folding static-dissipating work mat.
