Planning the Installation

Optimum Environment

When installing the ProLiant BL p-Class system in a rack, select a location that meets the environmental standards described in the following paragraphs.

Rack Requirements

The ProLiant BL p-Class system is compatible with the following racks:
42U, 36U, and 22U Compaq branded racks
— Compaq branded 10000 and 9000 Series racks (42U, 36U, and 22U) are
compatible. (The system is optimized for 10000 Series racks.)
— Compaq branded 7000 Series 42U racks require an extension kit (P/N
154392-B21) to increase rack depth from 83.82 cm (33 inches) to 93.98 cm (37 inches). The 7000 Series 36U and 22U racks are not compatible.
Telco racks
Third-party rack cabinets that meet the following requirements:
— Standard 48.26-cm (19-inch) width
— Depth of 73.66 cm (29 inches) between front and rear RETMA rails
— Minimum 7.62 cm (3 inches) clearance between rear RETMA rails and rear
rack door to accommodate system cabling
— Front and rear doors must have a minimum of 65 percent open area to
provide adequate airflow

Space and Airflow Requirements

To enable servicing and adequate airflow, observe the following spatial requirements when deciding where to install a Compaq branded, telco, or third-party rack:
Leave a minimum clearance of 63.5 cm (25 inches) in front of the rack.
Leave a minimum clearance of 76.2 cm (30 inches) in back of the rack.
Leave a minimum clearance of 121.9 cm (48 inches) from the back of the rack to
the rear of another rack or row of racks.
2-2 HP ProLiant BL p-Class System Setup and Installation Guide
Page 22
Planning the Installation
ProLiant servers 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 enable ambient room air to enter the cabinet, and the rear door must be adequately
ventilated to enable the warm air to escape from the cabinet.
IMPORTANT: Do not block the ventilation openings.
When any vertical space in the rack is not filled by servers or rack components, the
gaps between the components cause changes in airflow through the rack and across
the servers. Cover all gaps with server blanks to maintain proper airflow.
Compaq branded 9000 Series racks provide proper server cooling from flow-through
perforations in the front and rear doors that provide 65 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)] to provide proper front-to-back airflow and cooling.
CAUTION: Always use server blanks to fill empty vertical spaces in the rack. This arrangement ensures proper airflow. Using a rack without server blanks results in improper cooling that can lead to thermal damage.

Temperature Requirements

To ensure continued safe and reliable equipment operation, install or locate the
system in a well-ventilated, climate-controlled environment.
The maximum recommended ambient operating temperature (TMRA) for most
server products is 35°C (95°F). The temperature in the room where the rack is
located must not exceed 35°C
HP ProLiant BL p-Class System Setup and Installation Guide 2-3
(95°F).
Page 23
Planning the Installation

Power Requirements

WARNING: Risk of fire or damage to the equipment.
Each AC power cord for the power enclosure has an electrical rating based on the model and power supply configuration. The rating is marked on the side of the enclosure. It is important that the system be configured and loaded according to the guidelines in the ProLiant BL p-Class System Overview and Planning white paper. Failure to follow these guidelines may result in an overload of the electrical circuits feeding the power enclosure.
Also, when performing system upgrades, you must refer back to the ProLiant BL p-Class System Overview and Planning white paper to be sure that the new configuration does not overload the existing power enclosure scheme.
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 your facility’s wiring and installation requirements.
The installation of this equipment shall be in accordance with local/regional electrical regulations governing the installation of information technology 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 Edition (code for Protection of Electronic Computer/Data Processing Equipment).

Grounding Requirements

For proper operation and safety, the server must be properly grounded. 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, the equipment must be installed in accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code.
In all other countries, the installation must follow any regional or national electrical wiring codes, such as the International Electrotechnical Commission (IEC) 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.

System Warnings and Cautions

Before installing the system, carefully review the following warnings and cautions:
WARNING: To reduce the risk of personal injury or damage to equipment, heed all warnings and cautions throughout the installation instructions.
WARNING: To reduce the risk of electric shock or damage to the equipment, only enter or perform service on specific parts of the system as instructed in the user documentation.
WARNING: A risk of electric shock from high leakage current exists. Before connecting the AC supply to the power enclosures, be sure that the electrical outlets are properly earth grounded.
WARNING: A risk of injury from electric shock and hazardous energy levels exists.
Each power enclosure has two separate power supply cords. A single rack/cabinet may contain up to two power enclosures. In all cases, power is supplied in a redundant fashion and removing any single source of power does not necessarily shut down any portion of the system. When performing any service other than hot-plug module replacement, you must completely disconnect all power to that portion of the system.
In the case of the server blade enclosures, shut off the circuit breakers to both A and B power feeds and then disconnect both power feed cables before servicing.
In the case of the power enclosures, shut off the circuit breakers to both A and B power feeds and then disconnect both power cords from the wall outlet before servicing.

Observe local occupational health and safety requirements and guidelines
for manual material handling.
Remove hot-plug power supplies and server blades from their enclosures
before installing or removing the enclosures.
Use caution and get help to lift and stabilize enclosures during installation
or removal, especially when the enclosure is not fastened to the rack.
WARNING: To reduce the risk of personal injury or damage to the equipment, you must adequately support the power enclosure and the server blade enclosure during installation and removal. These enclosures are not secured to the rack frame.
WARNING: Always use at least two people to lift an enclosure into the rack. If the enclosure is being loaded into the rack above chest level, a third person must assist with aligning the enclosure with the rails while the other two people support the weight of the enclosure.
CAUTION: When performing non-hot-plug operations, you must power down the
server blade and/or the system. However, it may be necessary to leave the server blade powered up when performing other operations, such as hot-plug installations or troubleshooting.
CAUTION: Protect the equipment from AC power fluctuations and temporary interruptions with a regulating facility UPS device. This device protects the hardware from damage caused by power surges and voltage spikes and keeps the system in operation during a power failure.
CAUTION: Always be sure that equipment is properly grounded before beginning any installation procedure. Electrostatic discharge resulting from improper grounding can damage electronic components. For more information, refer to Appendix B, “Electrostatic Discharge.”
