NVR LED
Codes
The NVR 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 NVR
diagnostics and interpret the error information using the:
•
SHOW ERROR command
•
Diagnostic information in Chapter 4
•
Diagnostic error messages in Chapter 14
If the system does not enter console mode (>>>) or if hex code
DD is not displayed on the LEDs, then use Table 5–5 and then
perform the specified steps in Table 5–6 to isolate the failed
FRU.
