Rear Panel Overview

The enclosure rear view is shown below. The rear panel provides
access to all enclosure components. A description of each rear panel
component is given below:
˙
RAID controller module: One (1) controller module is installed
in the subsystem. It contains a main circuit board, which
processes I/O requests and RAID parity computation for data
protection and provides high data throughput for application
servers. (See Section 1.3.3.)
˙
PSUs: Two (2) hot-swappable PSUs supply power to the
subsystem. Power on/off is controlled by the individual power
switches on the power supplies. (See Section 1.3.5.)
˙
Cooling Modules: Three (3) redundant cooling modules
ventilate the system with an airflow direction from the front to the
rear. (See Section 1.3.6)
1.2.3

Internal Backplane

An integrated backplane board separates the front and rear sections
of the chassis. This circuit board provides logic level signals and low
voltage power paths. Thermal sensors and I
implemented in order to receive temperature/voltage readings and
module presence signals. This board contains no user-serviceable
components.
