7-segment display
The 7-segment display shows the box ID number assigned to the enclosure based on how it is connected
to the controller. If there are multiple enclosures attached to the controller, the box ID number identifies
the order in which they are attached.
NOTE:
Depending on your environment, you can also view device information through management software
utilities, such as the HP System Management Home page, HP Systems Insight Manager (HP SIM),
Storage Management Utility (SMU), or Command Line Interface (CLI).

2 Deployment types
The following types of deployments are supported:
• Single domain
In a single domain deployment, one path exists from the disk enclosure to the host. In a single
domain deployment, only one I/O module in the disk enclosure is used
• Dual domain
In a dual domain deployment, two paths exist from the disk enclosure to the host. In a dual domain
deployment, both I/O modules in the disk enclosure are used. Because dual domain deployments
provide two paths to the storage, access is ensured, even in the event of device, cable, or power
failure. In dual domain environments, dual-port disk drives are required.
• Server attached (single or dual domain)
In a server attached deployment, the disk enclosure is connected to a controller card installed in
a server. Several models of controller cards are supported for use with this disk enclosure. For
more information, see the QuickSpecs for the disk enclosure.
• Controller enclosure attached (single or dual domain)
In a controller enclosure attached deployment, the disk enclosure is connected to a rack-mounted
array controller enclosure. The controller enclosure is then connected to the server or network.
Several models of array controller enclosures are supported for use with this disk enclosure. For
more information, see the QuickSpecs for the disk enclosure.

3 Installing the enclosure
Environmental 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 airflow requirements
when deciding where to install a rack:
• Leave minimum clearance of 63.5 cm (25 in) in front of the rack.
• Leave minimum clearance of 76.2 cm (30 in) behind the rack.
• Leave minimum clearance of 121.9 cm (48 in) from the back of the rack to the back of another
rack or row of racks.
HP enclosures 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 adequately 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.
CAUTION:
When a vertical space in the rack is not filled by a server or rack component, the gaps between the
components cause changes in airflow through the rack and across the servers. Always use blanking
panels to fill empty vertical spaces in the rack. This arrangement ensures proper airflow. Using a rack
without blanking panels results in improper cooling that can lead to thermal damage.
The 9000 and 10000 Series racks provide proper server cooling from flow-through perforations in
the front and rear doors that provide 64 percent open area for ventilation.
CAUTION:
When using a Compaq-branded 7000 Series rack, you must install the high airflow rack door insert
[P/N 327281-B21 (42U) or P/N 157847-B21 (22U)] to provide proper front-to-back airflow and
cooling.
70 Modular Smart Array User Guide 13
CAUTION:
If a third-party rack is used, observe the following additional requirements to ensure adequate airflow
and to prevent damage to the equipment:
• Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow 5,350
sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate airflow
(equivalent to the required 64 percent open area for ventilation).
• Side—The clearance between the installed rack component and the side panels of the rack must
be a minimum of 7 cm (2.75 in).
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 most enclosure products is
35°C (95°F). The temperature in the room 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 in-
ternal rack temperature beyond the maximum allowable limits.
• Do not exceed the manufacturer’s 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 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 provides 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 interruptions with a regulating
uninterruptible power supply (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 one enclosure, you may need to use additional power distribution devices
to safely provide power to all devices. Observe the following guidelines:
Installing the enclosure14
• 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 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), 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-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 enclosure is not recommended.
Rack planning resources
The rack resource kit ships with all HP-branded or Compaq-branded 9000, 10000, and H9 Series
racks. For more information on the content of each resource, see the rack resource kit documentation.
If you intend to deploy and configure multiple servers in a single rack, see the white paper on
high-density deployment at the HP website: http://www.hp.com/products/servers/platforms.
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 become unstable if more than one com-
ponent is extended for any reason.
70 Modular Smart Array User Guide 15
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.
