1 Power supply error LED
When the power supply error LED is lit in amber, it indicates that there is a power supply problem. To identify
the failing power supply, check the status LED near the power cord connector on the redundant power
supply. When the status LED is lit in green, it indicates that the power supply is working correctly. When the
status LED is lit in amber, it indicates that the power supply is likely to fail or has failed.
2 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.
3 System fan error LED
When the system fan error LED is lit in amber, it indicates that one or more system fans are operating
slowly or have failed. To identify the failing system fans, check the status LEDs on the system board.
See “System board LEDs” on page 41.
4 Memory module status LED
When the memory module status LED is lit in amber, it indicates that one or more memory modules are
overheated.
