Temperature Requirements; Power Requirements - HP ProLiant DL320s User Manual

CAUTION:
adequate airflow and to prevent damage to the equipment:
• Front and rear doors—If the 42U rack includes closing front and rear doors, you must allow
5,350 sq cm (830 sq in) of holes evenly distributed from top to bottom to permit adequate
airflow (equivalent to the required 64 percent open area for ventilation).
• Side—The clearance between the installed rack component and the side panels of the rack
must be a minimum of 7 cm (2.75 in).

Temperature requirements

To ensure continued safe and reliable equipment operation, install or position 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 (95°F).
CAUTION:
Do not permit optional equipment to impede airflow around the server 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 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
(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:
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:
regulating uninterruptible power supply (UPS). This device protects the hardware from damage
caused by power surges and voltage spikes and keeps the system in operation during a power
failure.
When installing more than one server, you may need to use additional power distribution devices to
safely provide power to all devices. Observe the following guidelines:
•
Balance the server 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 the server.
If a third-party rack is used, observe the following additional requirements to ensure
To reduce the risk of damage to the equipment when installing third-party options:
