About the DIMM and Processor Test Circuit

You can identify failed DIMM and processor components by removing the server module from the chassis and pressing the internal Fault Remind test circuit button. The Fault Remind test circuit lights the failed component's Fault LED indicator.

Use the test circuit wthin 30–60 minutes. After you remove the server from the chassis (and its power source) and press the internal Fault Remind test circuit button, you have 30–60 minutes before the charge dissipates completely and disables the test circuit.

To determine if the circuit is usable, press the Fault Remind button and verify that the green Charge Status indicator is lit.

• If the Charge Status indicator lights, the circuit is usable and you can look for an amber Fault indicator to identify the failed component.

• If the Charge Status indicator does not light, the circuit has no charge; the error information is lost, and you need to install the server module into the chassis and power on to recharge the circuit and allow the error to occur again.
