HP MSA System Racking Instructions

Power requirements
Installation of this equipment must comply with local and regional
electrical regulations governing the installation of IT equipment by licensed
electricians . This equipment is designed to ope rate 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.
WARNING!
To reduce the risk of personal injury, fire, or damage to the
equipment, do not overload the AC supply branch circuit that
provid es power to the r ack. Consult the electrical authority having
jurisdiction over wiring and installation requirements of your
facility.
CAUTION:
Protect the enclosure 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 enclosure in operation during a power
failure.
When installing more than o ne enclosure , you may need to use additional
power distribution devices to safely provide power to all devices. Observe
the following guidelines:
• Balance the enclosure power load between available AC supply
branch circuits.
• Do not allow the overall system AC current load to exceed 80 percent
of the branch circuit AC current rating.
• Do not use common power outlet strips for this equipment.
• Provide a separate electrical circuit for each power supply in the en-
closure.
Electrical grounding requirements
The enc losure must be grounded pr ope rly fo r proper oper ation 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
enclosures connected to the same power source, HP recommends the use
of a power distribution unit (PDU) that is either permanently wired to the
building’s branch circuit or includes a nondetachable cord that is wired
to an industrial-st yle plug. NEMA locking-style plugs or those complying
with IEC 60309 are considered suitable for this purpose. Using common
power outlet strips for the enclosure is not recommended.
Rack warnings
WARNING!
To reduce the risk of personal injury or damage to the
equipment, be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single -
rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may be-
come unstable if more than one component is extended for
any reason.
WARNING!
To reduce the risk of personal injury or equipment damage when
unloading a rack:
• At least two people are needed to safely unload the rack
from the pallet. An empty 42U rack can weigh as much as
115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and
may become unstable when being moved on its casters.
• Never stand in front of the rack when it is rolling down the
ramp from the pallet. Always handle the rack from both
sides.
