Every AS/400 or later machines have a '''panel''', either as hardware, or emulated in Software (for logical partitions, ''LPAR''s).

== Elements ==
The panel is comprised of these elements:
* Pushbutton ↑
* Pushbutton ↓
* Pushbutton ''Enter'' often colored blue,
* LC-Display, for output of System Reference Codes (SRC),
* Power pushbutton ⌽,
* LED (green) for showing the power state,
* LED (green), with a pictogram reminding of stairs (main processor activity),<ref>It is not the disk activity LED as it was usual with PCs was into the 2000s.</ref>
* LED (amber) with a vertical bar, cut in half and one half moved slightly horizontal.

Usually after plugging the power, the LCD will light up green.

== SRC 0000BBBB ==
If the machine shows 0000BBBB in the LCD and the amber LED is lit, this is a sign of the internal battery for powering the clock and retaining some settings in NVRAM is emptied. Usually, this is a CR2450 button type battery and can be easily replaced.

== Changing settings ==
Normally, the LCD shows two chars and two digits, like
01 B N
The meaning is:
* 01 - Show current IPL-Parameters
* B - (A B C D) IPL-Source
* N (N M) IPL-Mode

<blockquote>Beware, the panel allows to set a multitude of parameters to the system service processor card. Please don't wildly push buttons to see what will happen. Chances are you will change a setting and the machine will no longer IPL, or console connection is broken, or probably worse things.</blockquote>

=== Setting IPL Mode to source D, and mode manual ===
This example setting is needed to make the machine IPL from install media, such as tape or optical.

* Push ↑ once to set the digit display from 01 to 02. Confirm with ''Enter''.
* Push ↑ oder ↓ until the character display is showing <code>D M</code>.<ref>Older machines support concurrent setting of Source and Mode, newer support setting Source and Mode separately.</ref> Confirm with ''Enter''.
* Push the power button ⌽. You can now insert the I_BASE-CD into the optical drive.
