Troubleshooting Using LED Indicators

Step 1. Examine the front panel LEDs for warning or fault indications. The server LED flashes yellow with
a warning indication and flashes red with a fault indication. See “Front Control Panel LED
Indicators” on page 117.
Step 2. Examine the QuickFind Diagnostic Panel for indications of specific warning or fault indications.
The diagnostic LEDs present patterns that categorize the source of the warning or fault. See
“QuickFind Diagnostic Panel LED Indicators” on page 119.
Step 3. Check to make sure power is getting to the server. Plug a known working device into the power
outlet.
Step 4. Check for proper ventilation for the server. The server should have at least three inches of space
around the front and rear for proper airflow when installed in a rack.
NOTE Temperature problems may be caused by a fluctuating power supply.
Step 5. Check the server specifications and make sure the environmental temperature and voltage are in
the specified guidelines.
Step 6. Monitor the server to make sure you are not experiencing further temperature and voltage
problems.
Step 7. Check the SEL for the event that caused the BMC to shut the server off.
