Setup 21
When installing more than one server, you might need to use additional power distribution devices to
provide power to all devices safely. 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.
Managed Hybrid Service reminders
•
The Managed Hybrid Service contract includes all of the required onsite server maintenance,
provided that the server has been supplied as a part of the HPE Easy Connect solution. Do not
attempt to open the chassis or tamper with it in any way. Any such action is a breach of the Managed
Hybrid Service contract. Only qualified personnel authorized by the MSP supplying the server must
power on the server and connect it to the WAN and LAN on the user site.
•
Repeatedly cycling the power or shutting down the server at regular or irregular intervals is
discouraged for the following reasons:
o
These actions put the server under thermal stress as it warms up and cools down. This thermal
stress can reduce the server lifecycle.
o
These actions prevent the server from being monitored remotely, which in turn jeopardizes the
achievement of service level commitments.
o
These actions can lead to data corruption, particularly on a server cluster. If data corruption
occurs, data from the backup will be used to restore the data. This backup data might not match
the most recently changed data before the data corruption.
•
Notify the MSP at least seven (7) days in advance of any planned electrical work that might result in
a power interruption. This notification will allow Hewlett Packard Enterprise to arrange for an orderly
shutdown of the server during the duration of the electrical work.
Prerequisites for preparing the server for installation
Before installation, the user must:
•
Verify that the optimum environmental requirements are satisfied (" Operating environmental
requirements " on page 20 ).
