Processor Board Led Blink Codes - HP LC2000r - NetServer - 128 MB RAM Handbook

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.
Diagnostic LEDs:
DIMM 3
DIMM 2
DIMM 1
DIMM 0
