ASIC LED Codes
The ASIC LED codes represent continued power-on testing. If an error occurs during this
testing sequence, a hexadecimal code appears with FRU and error code information on the
monitor screen.
If the system does not enter console mode (>>>) , or hex code DD is not displayed on the
LEDs, then use Tables 1-3 and 1-4 to isolate the failed FRU.
