2-2 Setting Up the System
Overview
This chapter describes how to select a site, assemble the rack-mount system
unit, make cable connections, and power on the tower-based or rack-mount
system units. Information on front and rear panel features, switches and LEDs
are also included in this chapter.
Selecting a Site
The system operates reliably in a typical office environment.
Choose a site that is:
!
Near grounded, three-pronged power outlets.
Note
: For the United States and Canada, this means a
NEMA 5-15R outlets for 100-120 VAC or NEMA 6-15R
outlets for 200-240 VAC. For other international sites, this
means three-pronged power outlets applicable for the
electrical code of the region.
!
WARNING
Be sure the power service connection is through a properly
grounded outlet.
!
CAUTION
When two power supplies are installed in the system the
power plug from each of the power supplies must be
plugged into the same common ground power outlets.
!
Clean, dust-free, and well ventilated. Front and rear ventilating openings
kept free of obstructions. Away from sources of heat, vibration or
physical shock.
!
Isolated from strong electromagnetic fields and electrical noise produced
by electrical devices (such as air conditioners, large fans, large electric
motors, radio and TV transmitters, and high-frequency security devices)
!
Spacious enough to provide at least five inches (13 centimeters) behind
the system and three inches (eight centimeters) on each side of the system
for proper cooling, airflow, and cable clearance.
!
Easily accessible for system maintenance and installation of system
upgrades.
