2-2 Setting Up The DAU
Overview
This chapter describes how to select a site, unpack the DAU and provides you
with assembly information for preparing and mounting the DAU into a system
rack. Also described are DAU to host cabling configurations, connecting the
power cord(s), powering On/Off the DAU, and configuring the Fibre Channel
address switches.
Selecting a Site
The DAU 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
Be sure that the power plug from each of the power supplies
is 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 DAU and three inches (eight centimeters) on each side of the DAU
for proper cooling, airflow, and cable clearance.
Note: Provide an additional five inches (13 centimeters)
behind the DAU to facilitate changing the self-contained hot-
swap power supply unit.
