Server Module Maintenance Procedures and Information
When DIMMs or CPUs have a fault, the system lights the front panel Service Action Required LED. The LED indicates that immediate service action is required. To address the issue, the server must be powered down and removed from the chassis, so you can use the internal on-board test circuitry to identify the failed component.
The test circuitry is a charged circuit that has a time-limited window of usability (30–60 minutes). When the Fault Remind button is pressed, a Charge Status LED lights if the circuit is usable. If too much time has elapsed between removing the server module and using the test circuit, the charge can drain completely. If this happens, the circuit becomes unusable (and the LED turns off). When the test circuit is drained, the error information is lost. For the circuitry to become usable again, the server module must be installed in the chassis, and the error must occur again.
Tip - When diagnosing DIMM and CPU errors, the best practice is to remove the server module from the server and use the test circuitry as soon as possible.
For information about how to identify faulty DIMMs or CPUs using the on-board fault test circuits, see the following procedures:
