Power Switch
The power switch controls the supply of AC power to the module. The switch
is recessed into the front panel to prevent accidental power-up or power-down.
Press 1 to turn the module on and press 0 to turn the module off.
Control Panel
The Base Module Control Panel (Figure 2–4) contains four LED indicators, a
four–line by 20–character backlit LCD display, and four pushbuttons.
LED Indicators
The four LED indicators on the Control Panel are labeled Ready (green), Use
Cleaner (yellow), Drive Fault (red), and Loader Fault (red).
■ Ready (green) – lights when the Base Module is ready to accept
commands, either from the Control Panel or from the host computer via
the Expansion Unit. The Ready indicator goes out when you enter the
Menu Mode.
■ Use Cleaner (yellow) – indicates that either or both drives require
cleaning. A cleaning operation should be done as described in Chapter
5, Regular Maintenance. When the Use Cleaner LED comes on, you
can find out which drive needs cleaning by selecting Cleaning Needed
on the Drive status submenu.
■ Drive Fault or Loader Fault (red) – lights when a Fault Screen appears
on the LCD display. The Fault Screen is described later in this chapter.
A list of Fault Symptom Codes (FSC) and Error Recovery Procedures
(ERP) appears in Chapter 5, Regular Maintenance.
