The Liquid Crystal Display (LCD) is located on the left side of the front

characters wide. The LCD displays messages about the state of the

 

system, including chassis codes. The symbols in Figure 1-2 appear in the

 

LCD if you have the HP-UX 10.20 operating system and the Workstation

 

Additional Core Enhancements for HP-UX 10.20 (June 1999) booted on

 

your system. They represent the different system activities shown:

“LCD Information” in Chapter 7 of this document.

 

System Power Switch

 

The power switch is used to turn the system unit on and off. When you

 

turn your computer off, the operating system executes an automatic

 

shutdown -qcommand. This prevents any damage to programs and

 

data on your system disk. Turning the power switch back on again

 

automatically boots up the HP-UX 10.20 operating system and the

 

Workstation Additional Core Enhancements for HP-UX 10.20 (June

 

1999) if your system has been configured to auto boot. For information on

 

setting auto boot, read the section “Setting the Auto Boot and Auto

 

Search Flags” in Chapter 6 of this document.
