Motherboard Status Indicators

The motherboard contains the following status indicators (LEDs).
Status Indicator Description
DIMM Fault Status ■ Each of the 24 DIMM sockets on the motherboard has an amber fault status indicator
Indicators (LED) associated with it.
■ If Oracle ILOM determines that a DIMM is faulty, pressing the Fault Remind button on
the motherboard I/O card signals the service processor to light the fault LED associated
with the failed DIMM.
■ For more information on DIMM fault status indicators and the location of the Fault
Remind button, see
Processor Fault ■ The motherboard includes a fault status indicator (LED) adjacent to each of the two
Status Indicators processor sockets.
■ These LEDs indicate when a processor fails.
■ Pressing the Fault Remind button on the motherboard I/O card signals the service
processor to light the fault status indicators associated with the failed processors.
■ For more information on processor fault status indicators and the location of the Fault
Remind button, see
Fault Remind Status ■ This status indicator (LED) is located next to the Fault Remind button and is powered
Indicator from the super capacitor that powers the fault LEDs on the motherboard.
■ This LED lights to indicate that the fault remind circuitry is working properly in
cases where no components failed and, as a result, none of the component fault LEDs
illuminate.
■ For more information on the fault remind status indicator and the location of the Fault
Remind button, see
STBY PWRGD ■ This green status indicator (LED) is labeled STBY PWRGD and is located on the
Status Indicator motherboard near the back of the server.
■ This LED lights to inform a service technician that the motherboard is receiving Standby
power from at least one of the power supplies.
■ This LED is provided to help prevent service actions on the server internal components
while the AC power cords are installed and power is being supplied to the server.

Troubleshooting System Cooling Issues

Maintaining the proper internal operating temperature of the server is crucial to the health of the
server. To prevent server shutdown and damage to components, address over temperature and
hardware-related issues as soon as they occur. If your server has a temperature-related fault, use
the information in the following table to troubleshoot the issue.
