fastened to the rack.
WARNING: To reduce the risk of personal injury or
damage to the equipment, you must adequately support
enclosures during installation and removal.
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.
WARNING: Before installing an enclosure in the rack, be
sure that all hot-plug power supplies, server blades, and
interconnects are removed from the enclosure. Blanks can be left
in the enclosure.
WARNING: Be sure to install enclosures starting from the
bottom of the rack and work your way up the rack.
These symbols, on power supplies or systems,
indicate that the equipment is supplied by multiple sources of
power.
WARNING: To reduce the risk of injury from electric shock,
remove all power cords to completely disconnect power from the
system.
10 HP BladeSystem p-Class Enclosure Installation Guide
Each power enclosure has two or more power supply cords. A
•
single rack or cabinet may contain more than one power
enclosure. Power may be supplied in a redundant fashion.
Removing any single source of power does not necessarily
remove power from 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.
• • When performing service procedures on server blade
enclosures, ensure that both A and B DC power feeds are
disconnected from the enclosure before servicing.
When performing service procedures on power enclosures,
shut off the circuit breakers to both A and B AC power feeds
and then disconnect both power cords from the wall outlet
before servicing.
WARNING: To reduce the risk of personal injury from hot
surfaces, allow the drives and the internal system components to
cool before touching them.
WARNING: To reduce the risk of electric shock or damage
to the equipment, enter enclosures or perform service on system
components only 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
grounded (earthed).
CAUTION: Always be sure that equipment is properly
grounded and that you follow proper grounding procedures before
beginning any installation procedure. Improper grounding can result in
ESD damage to electronic components. For more information, refer to,
"Electrostatic Discharge (on page 93
CAUTION: When performing non-hot-plug operations, you
must power down the server blade and/or the system. Use caution
when performing other operations, such as hot-plug installations or
troubleshooting.
)."
Planning the installation 11
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.
IMPORTANT: Data on the dimensions and weights of HP BladeSystem
p-Class components can be found in the HP BladeSystem p-Class
System Maintenance and Service Guide. The same data can be
determined by using the online HP BladeSystem p-Class Sizing Utility.
Space and airflow requirements
To enable servicing and ensure adequate airflow, observe the following spatial
requirements when deciding where to install an HP branded, Compaq branded,
telco, or third-party rack:
•
Leave a minimum clearance of 63.5 cm (25 in) in front of the rack.
•
Leave a minimum clearance of 76.2 cm (30 in) in back of the rack.
•
Leave a minimum clearance of 121.9 cm (48 in) from the back of the rack to
the rear of another rack or row of racks.
HP BladeSystem servers draw cool air in through the front and expel warm air
through the rear of the enclosure. Therefore, the front of the rack enclosure must
be adequately ventilated to enable ambient room air to enter the enclosure, and
the rear of the enclosure must be adequately ventilated to enable the warm air to
escape from the enclosure.
IMPORTANT: Do not block the ventilation openings.
If the front of the rack is not completely filled with components, the remaining
gaps between the components can cause changes in the airflow, which can
adversely affect cooling within the rack. Cover these gaps with blanking panels.
CAUTION: 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.
12 HP BladeSystem p-Class Enclosure Installation Guide
Compaq branded 9000 Series racks provide proper server cooling from flowthrough perforations in the front and rear doors that provide 65 percent open area
for ventilation.
CAUTION: Always use blanks to fill empty spaces in
enclosures. This arrangement ensures proper airflow. Using an
enclosure without the proper blanks results in improper cooling that can
lead to thermal damage.
Temperature requirements
To ensure continued safe and reliable equipment operation, install or position the
rack in a well ventilated, climate-controlled environment.
The operating temperature inside the rack is always higher than the room
temperature and is dependent on the configuration of equipment in the rack.
Check the TMRA for each piece of equipment before installation.
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
equipment or to increase the internal rack temperature beyond the
maximum allowable limits.
Do not exceed the manufacturer’s TMRA.
Power requirements
WARNING: A risk of fire or damage to the equipment
exists.
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.
Planning the installation 13
It is important that the system be configured according to the
guidelines in the HP BladeSystem 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.
When performing system upgrades, refer to the HP BladeSystem
p-Class System Overview and Planning white paper to be sure that
the new configuration does not overload the existing power
enclosure scheme.
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, refer to 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 equipment 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 equipment in operation during a power failure.
Grounding requirements
This equipment 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.
14 HP BladeSystem p-Class Enclosure Installation Guide
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 this equipment, HP
recommends the use of a 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 to supply
power to this equipment is not recommended.
