LCD and LCD Control Panel

The 2-line, 24-character, alphanumeric LCD displays startup and status
messages.
The LCD control panel consists of four buttons located under the LCD. These
buttons allow you to perform a reset and, for the CEC 20 module, to access the
Diagnostic Main Menu.
To perform a reset, simultaneously press the outer buttons, which are
marked Reset.
To access the Diagnostic Main Menu, simultaneously press the two inner
buttons, which are marked ATTENTION. The menu is displayed on the LCD. For
complete information on the Diagnostic Main Menu, refer to the NETBuilder II
CEC 20 Module Installation Guide. The DPE module does not support the
Diagnostic Main Menu.

POWER and STATUS LEDs

Below and to the left of the LCD control panel are two LEDs marked POWER
and STATUS. The POWER LED indicates whether the system is on or off and is
the same as the POWER LED on the main processor module.
If you are using a DPE module, the STATUS LED on the chassis is the same as
the POWER/FAULT LED on the DPE module. Refer to the DPE module guide for
more information about this LED.
If you are using a CEC 20 module, the STATUS LED on the chassis is the same
as the STATUS LED on the CEC 20 module. Refer to the CEC 20 module guide
for more information about this LED.
