Console LED Codes
The last testing sequence before entering the console program now begins. If this is
successful, the LEDs should display hex code DD for console entry.
If the system does not enter console mode, use Tables 1-16 and 1-17 to isolate the failed
FRU.
No information appears other than the console (>>>) prompt or the DD hex code to
indicate that the console mode has been entered.
