Codes
The Memory LED codes represent continued power-on testing. If
an error occurs during this testing sequence, then a hexadecimal
code appears with FRU and error code information on the
monitor screen.
If the system enters console mode, then execute the MEMORY
diagnostics and interpret the error information using the:
•
SHOW ERROR command
•
Diagnostic information in Chapter 4
If the system does not enter console mode (>>>) or hex code DD
is not displayed on the LEDs, then replace the failing SIMM.
