Unpacking The SWXRA-Yx RAID Array 410 Subsystem
This chapter describes the site preparation and unpacking procedures for the SWXRA-Yx RAID Array 410
Subsystem.
1.1 Site Preparation
The SWXRA-Yx RAID Array 410 Subsystem is designed for installation in Federal
Communications Commission (FCC) Class A environments. Before installing the SWXRA-
Yx, make sure that adequate space is available in front of the enclosure for opening the front
door (19 inches clearance) and around the enclosure for adequate airflow. See Figure 1–1 for
specific space requirements.
