System Interface

4-1  Overview

There are several LEDs on the control panel as well as others on the drive carriers 
to keep you constantly informed of the overall status of the system as well as the 

activity and health of specific components. Most SC835 models have two buttons 

on the chassis control panel: a reset button and an on/off switch. This chapter ex-
plains the meanings of all LED indicators and the appropriate response you may 
need to take.
