Identify Faulty DIMMs

Caution - Component damage. This procedure requires that you handle components that are sensitive to static discharge. This sensitivity can cause the component to fail. To avoid damage, ensure that you follow electrostatic discharge safety measures and antistatic practices. See Performing ESD and Antistatic Prevention Measures.

Verify that the charge status LED is lit green.
A lit green Charge Status LED, located next to the Fault Remind button, indicates that the Fault Remind LED circuit is operational.

Note - The Charge Status LED indicates the test circuit power level. If the Charge Status LED is out, the Fault Remind LEDs can not function. After the server module is inserted into the Sun Blade chassis, the test circuit will recharge. However, any DIMM errors must reoccur to be stored and visible on a DIMM Fault LED during the next fault remind test.
To identify a faulty DIMM, press and hold the blue Fault Remind button on the motherboard (SW3001).
Release the button after an amber DIMM Fault LED lights. Do not hold the Fault Remind button down longer than necessary.
For information about using the DIMM test circuit, see Using the DIMM and Processor Test Circuit .
Note the location of the faulty DIMMs on the motherboard.
A lit amber LED next to a DIMM slot indicates a faulty DIMM.

Faulty and should be replaced.
Ensure that all DIMMs are seated correctly in their connector slots.
If re-seating the DIMM does not fix the problem, remove and replace the faulty DIMM.

Note - The DIMM Fault LED remains on when the Fault Remind button is pressed after the DIMM is re-seated. The server module must be powered up again to verify if re-seating fixes the DIMM problem.
