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,
CAUTION: When performing non-hot-plug operations, you
must power down the server blade and/or the system. Use caution

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 flow-
through 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.

Federal Communications Commission notice
Part 15 of the Federal Communications Commission (FCC) Rules and
Regulations has established Radio Frequency (RF) emission limits to provide an
interference-free radio frequency spectrum. Many electronic devices, including
computers, generate RF energy incidental to their intended function and are,
therefore, covered by these rules. These rules place computers and related
peripheral devices into two classes, A and B, depending upon their intended
installation. Class A devices are those that may reasonably be expected to be
installed in a business or commercial environment. Class B devices are those that
may reasonably be expected to be installed in a residential environment (for
example, personal computers). The FCC requires devices in both classes to bear
a label indicating the interference potential of the device as well as additional
operating instructions for the user.
FCC rating label
The FCC rating label on the device shows the classification (A or B) of the
equipment. Class B devices have an FCC logo or ID on the label. Class A
devices do not have an FCC logo or ID on the label. After you determine the
class of the device, refer to the corresponding statement.
Class A equipment
This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at
personal expense.

Preventing electrostatic discharge
To prevent damaging the system, be aware of the precautions you need to follow
when setting up the system or handling parts. A discharge of static electricity
from a finger or other conductor may damage system boards or other static-
sensitive devices. This type of damage may reduce the life expectancy of the
device.
To prevent electrostatic damage:
•
•
•
Avoid hand contact by transporting and storing products in static-safe
containers.
Keep electrostatic-sensitive parts in their containers until they arrive at static-
free workstations.
Place parts on a grounded surface before removing them from their
containers.
•
•
Avoid touching pins, leads, or circuitry.
Always be properly grounded when touching a static-sensitive component or
assembly.

HP BladeSystem p-Class Enclosure Installation Guide
Grounding methods to prevent electrostatic
discharge
Several methods are used for grounding. Use one or more of the following
methods when handling or installing electrostatic-sensitive parts:
•
Use a wrist strap connected by a ground cord to a grounded workstation or
computer chassis. Wrist straps are flexible straps with a minimum of
1 megohm 10 percent resistance in the ground cords. To provide proper
ground, wear the strap snug against the skin.
•
Use heel straps, toe straps, or boot straps at standing workstations. Wear the
straps on both feet when standing on conductive floors or dissipating floor
mats.
•
•
Use conductive field service tools.
Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an
authorized reseller install the part.
For more information on static electricity or assistance with product installation,
contact an authorized reseller.
