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: • Do not permit optional equipment to impede airflow 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. 20 Setting up the enclosure

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:
•
Do not permit optional equipment to impede air
fl
ow 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,
fi
re, 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
fl
uctuations 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.
