Identifying LCD-Indicated Conditions

The B2000 workstation uses an LCD panel to display firmware/OS progress codes. The

codes, referred to as chassis codes, consist of one of the mnemonics listed below, followed by

a 4-digit hexadecimal number identifying the code module being executed. The mnemonics

and their meanings are:

FLT

A hardware error has been detected

TST

Hardware being tested

INI

Hardware being initialized

SHU

System being shutdown

WRN

A non-optimal or unusual operating condition exists

RUN

Computer is running operating system

In general, the LCD display has the following format:

MMM

CCCC

FFFFFF

Six-character Field Replaceable Unit (FRU) description

DDDDDDDDDDDDDDDD

If the system encounters an

FLT

code while the system is booting, the

FLT

interpreted and a message is displayed. For example, you may have information similar to

the following in the LCD:
