Recommended Corrective Action
For most of the blink code errors, the System Controller Board should be replaced.
For Hard Disk and DIMM slot errors, the cause of the error could be either the
System Controller Board or the plugged-in accessory. If the blink error points to a
(HD or RAM) component that is not even installed, the System Controller is to blame.
Otherwise, be prepared to replace either component (DIMM or HD and the System
Controller).
Power On LED Sequence
The following LEDs on the System Controller Board aid in identifying faults during
the Power On sequence. The LEDs provide status information in all powered ON
operating modes.
