LH Plus/Pro Processor Board LED Blink Codes
The Processor board in the NetServer LH Plus or 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).
