Internal Diagnostic LEDs
The server has internal fault LEDs for CPUs, DIMMs, and fan modules at the base of the CPUs, DIMMs, and fan modules.
1 |
Fan module fault LEDs (one on the top of each fan module)
|
3 |
DIMM fault LEDs (one behind each DIMM socket on the motherboard) These LEDs operate only when the server is in standby power mode.
|
2 |
CPU fault LEDs (one behind each CPU socket on the motherboard). These LEDs operate only when the server is in standby power mode.
