Chapter 2 Installing The System
Selecting a Site
The server operates reliably within the specified environmental limits (see
page 41). Choose a site that is
• near a grounded, three-pronged power outlet
a. In the United States and Canada, this means a NEMA 5-15R outlet
for 100-120 VAC or a NEMA 6-15R outlet for 200-240 VAC.
b. For international sites, this means a three-pronged power outlet
applicable for the electrical code of the region.

CAUTION
Ensure that the power service connection is through a
properly grounded outlet.
• clean and dust-free
• well ventilated and away from sources of heat
• spacious enough to provide sufficient room behind and around the
server so that you can remove AC power from it by unplugging the
power cord from each power supply or wall outlet
✏
Note
For cooling, airflow, and access to the server, allow about
31 centimeters (12.2 inches) of clearance in back,
60 centimeters (23.6 inches) on each side, and 22 centimeters
(9 inches) in front.
• isolated from strong electromagnetic fields and electrical noise caused
by electrical devices—such as air conditioners, large fans, large electric
motors, radio and TV transmitters, and high frequency security devices
• away from sources of vibration or physical shock
