WARNING To reduce the risk of personal injury or damage to the equipment, be sure that the rack is stabilized as follows: • The leveling feet are extended to the floor. • The full weight of the rack rests on the leveling feet. • The stabilizing feet are attached to the rack if it is a single-rack installation. • The racks are coupled together in multiple-rack installations. • Extend only one component at a time or the rack may become unstable. Data Center planning and considerations Environmental considerations The data center must meet certain environmental conditions for the rack implementation. Thermal considerations The racks should be configured and arranged in a data center to ensure proper air flow. Configuring a rack for proper air flow The increasing power of new high-performance processor technology requires increased cooling efficiency for rack-mounted servers. The 10000 Series Racks provide enhanced air flow for maximum cooling, allowing these racks to be loaded with a maximum of 8-10 KW. For extreme cases, refer to www.hp.com/go/mcs. CAUTION It is necessary to ensure that the components installed in the rack do not exceed the Manufacturer's Maximum Recommended Ambient Operating Temperature. Rack openings and perforations Slots, openings and perforations in the rack (especially in doors) provide ventilation, reliable operation, and prevent overheating and, therefore, should never be blocked or covered. To provide proper front-to-back air flow, any open "U" space in the front of a rack must be covered with a HP 10000 Series Universal Filler Panel. CAUTION Failure to cover open U spaces with blanking panels may result in improper cooling that can lead to thermal damage. Back-pressure air flow condition Certain rack configurations, such as racks with extreme cable or server density, may cause a backpressure situation to occur. When a back-pressure situation occurs, heated exhaust air is forced around the side of the server components and back into the server inlet. Contact an Authorized Service Provider if you suspect a back-pressure situation is occurring in a rack. 16

WARNING
To reduce the risk of personal injury or damage to the equipment, be sure that the rack is stabilized as follows:
•
The leveling feet are extended to the floor.
•
The full weight of the rack rests on the leveling feet.
•
The stabilizing feet are attached to the rack if it is a single-rack installation.
•
The racks are coupled together in multiple-rack installations.
•
Extend only one component at a time or the rack may become unstable.
Data Center planning and considerations
Environmental considerations
The data center must meet certain environmental conditions for the rack implementation.
Thermal considerations
The racks should be configured and arranged in a data center to ensure proper air flow.
Configuring a rack for proper air flow
The increasing power of new high-performance processor technology requires increased cooling
efficiency for rack-mounted servers. The 10000 Series Racks provide enhanced air flow for maximum
cooling, allowing these racks to be loaded with a maximum of 8–10 KW. For extreme cases, refer to
www.hp.com/go/mcs
.
CAUTION
It is necessary to ensure that the components installed in the rack do not
exceed the Manufacturer's Maximum Recommended Ambient Operating
Temperature.
Rack openings and perforations
Slots, openings and perforations in the rack (especially in doors) provide ventilation, reliable
operation, and prevent overheating and, therefore, should never be blocked or covered. To provide
proper front-to-back air flow, any open "U" space in the front of a rack must be covered with a HP
10000 Series Universal Filler Panel.
CAUTION
Failure to cover open U spaces with blanking panels may result in improper
cooling that can lead to thermal damage.
Back-pressure air flow condition
Certain rack configurations, such as racks with extreme cable or server density, may cause a back-
pressure situation to occur. When a back-pressure situation occurs, heated exhaust air is forced
around the side of the server components and back into the server inlet. Contact an Authorized
Service Provider if you suspect a back-pressure situation is occurring in a rack.
