complete, and the LED returns to its steady, lit state until the system turns off

Using the Operator Panel and Reset Switch
The operator panel on the front of the server contains a four-digit display and reset
button. The four-digit display is used by your server to display progress indicators
during system startup, and can also display error messages.
The function of the reset button depends on the operating system installed in the
server. Consult your operating system documentation for a description of its
function.
Working with System Startup Options
If no keys are pressed after the server power is turned on, the server searches a list
of devices (the

default boot list

) for a bootable image. If a bootable image is found,
then the server loads and starts the operating system. This is called a

normal boot

.
The server can also be booted from a

custom boot list

, which can be changed
through the System Management Services.
If certain keys are pressed during system startup, the server searches the default or
custom boot list for a bootable image to start in

service mode

instead of normal
mode. After a successful service mode boot, the diagnostic programs are started
automatically.
The following pages describe the default and custom boot lists, and how to boot from
these in either normal or service mode.
Default Boot List
The

default boot list

is composed of the first device found of each of the following
types:
1. Diskette drive
2. CD-ROM drive
3. Disk drive
4. Network device
