7-segment display board
The 7-segment display board allows you to identify the following:
•The port on the host controller to which the MSA70 is connected. There are two external ports on
the host controller; each port allows you to connect up to two MSA70s to the controller. Because
user guide 15

one additional MSA70 can be attached to each of the MSA70s, a total of four MSA70s can be
connected to the host controller. See Cascading (1+1) configuration.
•The box ID number assigned to the MSA70 based on how it is connected to the host controller.
If there are multiple MSA70s attached to the controller, the box ID number identifies the order
in which they are attached.
When the MSA70 is connected to the host controller, the controller automatically assigns the port and
box ID numbers to the enclosure. The following table shows MSA70 enclosures and their associated
port and box ID assignments:
Storage Enclosure Port Box ID
MSA70 enclosure 1 P1 B1
MSA70 enclosure 2 P1 B2
MSA70 enclosure 3 P2 B3
MSA70 enclosure 4 P2 B4
To view the port to which the MSA70 is connected, press the up arrow button on the 7-segment display
board. To view the box ID number, press the down button.
15487
You can also view the port and box ID numbers within Array Configuration Utility (ACU), HP Systems
Insight Manager (HP SIM), and Array Diagnostic Utility (ADU).

2 Powering up and powering down
the enclosure
IMPORTANT:
Before installing this product, read the
Important Safety Information document provided.
Powering up
Observe the following guidelines before powering up the enclosure:
•Install all components of the enclosure.
•Install hard drives in the enclosure so the connected host controller can identify and configure
them at powerup.
•Always power up the enclosure first, and then the server. This ensures that the servers, during
their discovery, see the enclosure as an operational device. If you do not power up the enclosure
before powering up the servers, you will need to power down the servers, ensure that the
enclosure is powered up, and then power back up the servers.
To power up the enclosure:
1. Complete server hardware installation and cabling. See the server documentation.
2. Connect the SAS cables and power cords to the enclosure. See Choosing a configuration.
3. Press and hold the Power On/Standby button. Wait and observe the system power LED and fan
modules. When the enclosure powers up, the system power LED illuminates solid green and the
fans spin to a high speed, and then spin down to a low speed.
4. Power up the servers. See the server documentation.
Powering down
CAUTION:
Be sure that the server is the first unit to be powered down and the last to be powered back up. Taking
this precaution ensures that the system does not erroneously mark the drives as failed when the server is
powered up.
IMPORTANT:
If installing a hot-plug device, it is not necessary to power down the enclosure.
To power down the enclosure:
1. Power down any attached servers. See the server documentation.
2. Press the Power On/Standby button on the enclosure. Wait for the system power LED to change
from green to amber.
3. Disconnect the power cords.
The system is now without power.

3 Setting up 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.
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—Theclearancebetweentheinstalledrackcomponentandthesidepanelsoftherackmustbea
minimum of 7 cm (2.75 in).
user guide 19

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.
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:
•Donotpermitoptionalequipmenttoimpedeairflow around the enclosure or to increase the internal
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 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:
•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.
