|1 BMC heart beat LED||2 System ID LED|
|3 System error LED||4 DIMM error LEDs (16)|
|5 Fan error LEDs (6)|
1 BMC heart beat LED
|On||Green||The BMC is not alive.|
|Blinking||Green||The BMC is alive.|
|Off||None||The BMC is not alive.|
2 System ID LED
The blue system ID LED helps you to visually locate the server. A system ID LED is also located on the front of the server. Each time you press the system ID button, the state of both the system ID LEDs changes. The LEDs can be changed to on, blinking, or off.
3 System error LED
When this yellow LED is lit, one or more LEDs elsewhere in the server might also be lit to direct you to the source of the error. For more information, see Front I/O assembly.
4 DIMM error LEDs
When a DIMM error LED is lit, it indicates that the corresponding memory module has failed.
5 Fan error LEDs
When a fan error LED is lit, it indicates that the corresponding system fan is operating slowly or has failed.
