4 Ambient temperature limit LED
When this LED is lit in amber, it indicates that the ambient temperature is below 7°C (44.6°F) or over 40°C
(104°F), which is not proper for server operation.
5 Microprocessor status LEDs (also known as CPU status LEDs)
When a microprocessor status LED is lit in amber, it indicates that the corresponding microprocessor is
overheated. For the microprocessor location(s), see “System board components” on page 47.
6 Power supply error LEDs
When a power supply error LED is lit in amber, it indicates that there is a power supply problem. For the
power supply location(s), see “Rear view of the server” on page 26. To identify the failing power supply, you
also might check the status LED near the power cord connector on the redundant power supply. When the
LED is lit in green, it indicates that the hot-swap redundant power supply is working correctly. When the LED
is lit in amber, it indicates that the hot-swap redundant power supply is likely to fail or has failed.
