48 Chapter 3 - Operation
Buttons - All Modules
There are four buttons on the control panel, labeled
Escape
,
Enter
,
▲
, and
▼
. The buttons do
not directly control specific functions or options. Instead, you use the buttons to navigate from
the Default Screen through a multi-level menu structure, then select the desired option from
the appropriate menu using the
Enter
button. Table 3-1 describes the effect of each of the four
buttons under various conditions.
The three most important things you need to know about the buttons are
1) To enter the Menu Mode and display the Main Menu from the Default Screen, press the
Enter
button.
2) To return to the Main Menu from a submenu, press the
Escape
button repeatedly until the
Main Menu appears. Pressing the
Escape
button while the Main Menu is displayed exits the
Menu Mode and returns you to the Default Screen. The Default Screen is shown in Figure 3-
6; the Main Menu is shown in Figure 3-10.
3) To display the Show Status Menu only without entering the Menu Mode, press the
Escape
button at the Default Screen. The system remains online.
Important Note: When you enter the Menu Mode at the Global Control Module, the
Ready
light on that module goes out. This means that the DLT LibraryXpress system is off-line, and
the system responds to all commands from the host with a SCSI ‘Not Ready’ until you exit
the Menu Mode and the
Ready
light goes on.
When you enter the Menu Mode at any of the slave modules, the Ready light on that module
goes out. This means that the individual module is off-line, and the system responds to all
commands from the host pertaining to that module with a SCSI ‘Not Ready’ until you exit the
Menu Mode and the
Ready
light goes on.
