Memory Module
The memory module (DIMM) diagnostic LED, located adjacent to each memory module socket,
indicates the condition of each DIMM. If the front panel critical system status LED is amber,
check the individual DIMM diagnostic LEDs to determine which DIMM has failed. To view the
diagnostic LEDs, remove the access panel of the server. See “Access Panel” in Chapter 2.
Figure 4-6 shows the DIMM diagnostic LED
locations in Compaq ProLiant ML530 servers.
Table 4-5 lists the corresponding DIMM diagnostic LED conditions. To replace a DIMM, see
“Memory Modules” in Chapter 2. The color of the status and diagnostic LEDs will reset when
the DIMM is replaced and system power is restored.

Processor
The processor diagnostic LED, located adjacent to each processor slot, indicates the condition of
each processor. If the front panel critical system status LED is amber, check the individual
processor diagnostic LEDs to determine which processor has failed. To view the diagnostic
LEDs, remove the access panel of the server. See “Access Panel” in Chapter 2.
Figure 4-6 shows the processor diagnostic LEDs
for Compaq ProLiant ML530 servers. Table
4-6 lists the corresponding processor diagnostic LED conditions. To replace a processor, see
“Processors” in Chapter 2. The diagnostic LED color will reset when the processor is replaced
and the system power is restored.
