This appendix contains information about the locations and behavior of the LEDs on the server. It describes the external LEDs that can be viewed on the outside of the server and the internal LEDs that can be viewed only with the main cover removed.

Internal Status Indicator LEDs
The server has internal status indicators on the motherboard.
- The DIMM Fault LEDs indicate a problem with the corresponding DIMM. See FIGURE B-7 and FIGURE B-8 for the LED locations.
When you press the Remind button, if there is a problem with a DIMM, the corresponding DIMM Fault LED flashes. See DIMM Fault LEDs for details.
- The CPU Fault LEDs indicate a problem with the corresponding CPU. See FIGURE B-9 and FIGURE B-10 for the CPU LED locations.
When you press the Remind button, if there is a problem with a CPU, the corresponding CPU Fault LED flashes.
Note - The DIMM Fault and CPU Fault LEDs operate on stored power for up to a minute when the system is powered down, even after the AC power is disconnected, and the motherboard is out of the system. The stored power lasts for about half an hour.
