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.
Racks provide proper server cooling from flow-through perforations in the front and rear doors that
provide a 65% open area for ventilation.
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:
To reduce the risk of damage to the equipment when installing third-party options:
• 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: 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 server from power fluctuations and temporary interruptions with a
regulating uninterruptible power supply. 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 might 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% 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.
