Determine Which DIMM Is Faulty (DIMM Fault Remind Button)
DIMMs are cold-service components that can be replaced by customers. For the location of the DIMMs, see Processor Module Components.
 | Caution - This procedure requires that you handle components that are sensitive to electrostatic discharge. This discharge can cause failure of server components. |
- Consider
your first steps:
Familiarize yourself with DIMM configuration rules.
Prepare the system for service.
Remove the processor module containing the faulty DIMM. Place the processor module on an ESD-protect work surface. Remove the processor module cover.
- Locate the DIMM Fault Remind
button on the processor module.
- Verify that the DIMM Fault Remind
Power LED next to the button is illuminated.
An illuminated DIMM Fault Remind Power LED indicates that there is power available to illuminate the faulty DIMM LED once you have pressed the DIMM Fault Remind button.
- Press the DIMM Fault Remind button
on the processor module.
This will cause DIMM Fault LED associated with the faulty DIMM to illuminate for a few minutes.
- Note the DIMM next to the illuminated DIMM Fault LED.
- Ensure that all other DIMMs are seated correctly in their slots.
