Chapter 1: Introduction 

An integrated backplane board separates the front and rear sections of the 

subsystems.  The PCB board provides traces for logic level signal traces and low 

voltage power paths. It contains no user-serviceable components. 

 

1.2 Subsystem Components 

All the active components on the subsystems can be accessed through either the front 

or rear panel. The modular design of the active components facilitates their easy 

installation and removal. Hot-swap mechanisms are incorporated to eliminate power 

surges and signal glitches that might occur while removing or installing these 

modules. 

 

The LCD panel shown in Figure 1-11 consists of a 16 characters x 2 rows LCD 

screen with push buttons, a mute button, and LED status indicators. The LCD front 

panel provides full access to all array configurations and monitoring. After powering 

up the subsystem, the initial screen will show the subsystem model name. A different 

name can be manually assigned to the subsystem or different drive arrays. This will 

enable easier identification in a topology consisting of numerous arrays. 

 

To access drive bays in the left- or right-hand side column, first flip the retention 

latches (see Figure 1-12) on the enclosure front handles, and then swing the handles 

to the left- and right-hand sides. To close the handles (see Figure 1-13),  swing the 

handles toward the system; gently press the handles until a click is heard. The latches 

will keep the handles in place.
