HP StorageWorks 2000 Modular Smart Array racking instructions (494159-001, July 2008)

Step 4: Prepare enclosure
Attach one side bracket to each side of the enclosure as shown, using
8-32 x 3/16 P hillips flat-head screws.
Step 5: Install enclosure
CAUTION:
Lifting and positioning a disk array enclosure requires two
people. You can lighten the enclosure by removing the hard
drives and rear components. If you remove components, be
sure to observe proper ESD precautions.
1. Slidetheenclosureallthewayintotherackontherailledges(1).
2. Attach the front of the enclosure to the rack with four 10-32 x 3/4
Phillips truss-head screws (2).
3. Fromtherearoftherack,attachtheenclosuresidebracketstothe

E:
Scr ew access can be improved by rotating the pow er
supply latch downward, especially on the right side. Be
sure to re-latch the pow er supply when done.
The enclosure is now ready for cabling and configuration. See the user
guide for further instructions.
Step 6: Install ears
Detailed site requirements
When installing the enclosure in a rack, select a location that meets the
environmental standards described in this section.
Space and airflow requirements
To allow for servicing and adequate airflow, observe the following space
and airflo
w requirements when deciding where to install a rack:
• Leave mi
nimum clearance of 63.5 cm (25 in) in front of the rack.
• Leave mi
nimum clearance of 76.2 cm (30 in) behind the rack.
• Leave m
inimumclearanceof121.9cm(48in)fromthebackofthe
rack to
the back of another rack or row of racks.
HP encl
osures draw in cool air through the front door and expel warm
air through the rear door. Therefore, the front and rear rack doors must
be adequately ventilated to allow ambient room air to enter the cabinet,
and the rear door must be a dequately ventilated to allow the warm air
to escape from the cabinet.
CAUTION:
To prevent improper cooling and damage to the equipment:
• Do not block the ventilation openings.
• Always use blanking panels to fill empty spaces in the rack.
Temperature requirements
To ensure continued safe and reliable equipment operation, install or
position the enclosure in a well-ventilated, climate-controlled environment.
The maximum recommended ambient operating temperature (TMRA) for
mostenclosureproductsis35°C(95°F).Thetemperatureintheroom
where the rack is located must not exceed 35°C (95°F).
CAUTION:
To reduce the risk of damage to the equipment when installing
third-party options:
• Do not permit optional equipment to impede airflow around
the enclosure or to increase the internal rack temperature
beyond the m aximum allowable limits.
• Do not exceed the manufacturer’s recommended ambient
operating temperature (TMRA).
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 operate 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 sup plied with that option.
WARNING!
To reduc
e the risk of personal injury, fire, or damage to the
equipme
nt, do not overload the AC supply branch circuit that
provide
s power to the rack. Consult the electrical authority
having
jurisdiction over wiring and installation requirements
of your facility.
CAUTION:
Protect the enclosure from power fluctuations and temporary
interr uptions with a regulating UPS. This device pr otects the
hardw
arefromdamagecausedbypowersurgesandvoltage
spik
es and keeps the enclosure in operation during a power
failure.
When installing more than one 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.
• Donotusecommonpoweroutletstripsforthisequipment.
• Provide a separate electrical circuit for each p ower supply in the
enclosure .
Electrical grounding requirements
The enclosure 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),
Article250,aswellasanylocalandregionalbuildingcodes. 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 na tional electrical wiring codes, such as the International
Electrotechnical Commission (IEC) Code 364, parts 1 through 7.
Furthermore,youmustbesurethatallpowerdistributiondevicesused
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 pow er 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-style plug. NEMA locking-style plugs or those
complying with I EC 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 multiplerack installations.
• Only one component is extended at a time. A rack may
become unstable if more than one component is extended
for any reason.
WARNING
!
To reduce the r isk 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.
