Processor Board LED Blink Codes The processor board in the NetServer LD Pro contains LEDs that can indicate memory errors and processor errors. When a memory error exists, the LEDs are either on, off, or flash repeatedly a constant memory error code. The table below describes each of these codes. If the memory error indicates a failed DIMM, replace the DIMM. When a processor error exists, the LEDs alternate between two codes (i.e., ON-OFF-OFF-OFF and OFF-ON-ON-ON). On = Steady green Flash = Regular, slow flash (1 Hz) Blink = Regular, fast flash Double-blink = Irregular, double-flash The diagnostic LEDs are located on the processor board, are labeled DIMM 0 through 3, and correspond to DIMM sockets 0 through 3. The LEDs are visible from either side of the board, and can also be viewed through the NetServer's rear panel cooling perforations.
