Introduction
1.1.1 Enclosure Chassis
The chassis consists of a sheet metal enclosure assembly containing a
backplane PCB and module runner system. This chassis assembly also
includes an integral Operators (Ops) Panel mounted at the rear.
The chassis assembly contains 16 drive bays at the front, each of which
accommodates a plug-in drive carrier module
(Figure 3). The 16 drive
bays are arranged in 4 rows of 4 drives. Bay numbers are defined by
column/row.
At the rear, there are 5 module bays to house two power supply/cooling
modules, two LRC I/O modules and the integral Ops panel
(Figure 4).
The Backplane PCB provides logic level signal and low voltage power
distribution paths.
The 4 × 4 chassis is fitted with 19 inch Rack mounting features which
enables it to be fitted to standard 19 inch racks and uses 3EIA units of
rack space.
