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, 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.

WARNING:

When all components are removed, the server weighs 20.10 kg (44.31 lb). When all components are installed, the server can

weigh up to 33.20 kg (73.19 lb).

Before configuring your rack solution, be sure to check the rack manufacturer weight limits and specifications. Failure to do

so can result in physical injury or damage to the equipment and the facility.

WARNING:

The server is heavy. To reduce the risk of personal injury or damage to the equipment, do the following:

Observe local occupational health and safety requirements and guidelines for manual material handling.

Get help to lift and stabilize the product during installation or removal, especially when the product is not fastened to

the rails. The server weighs more than 20.10 kg (44.31 lb), so at least two people must lift the server into the rack

together. An additional person may be required to help align the server if the server is installed higher than chest level.

Use caution when installing the server in or removing the server from the rack.

Adequately stabilized the rack before extending a component outside the rack. Extend only one component at a time. A

rack may become unstable if more than one component is extended.

Do not stack anything on top of rail-mounted component or use it as a work surface when extended from the rack.

WARNING:

To reduce the risk of personal injury or damage to the equipment, be sure that:

The rack has anti-tip measures in place. Such measures include floor-bolting, anti-tip feet, ballast, or a combination as

specified by the rack manufacturer and applicable codes.

The leveling jacks (feet) are extended to the floor.

The full weight of the rack rests on the leveling jacks (feet).

The stabilizing feet are attached to the rack if it is a single-rack installation.

The racks are coupled together in multiple rack installations.
