Interpreting LEDs
Use these steps to determine if an LED indicates that a component has failed in
the server.
|
|
|
1.
|
Check the LEDs on the front and rear of the server.
|
|
2.
|
Check the LEDs on the individual components.
Note -
Component LEDs might not be lit even though the component
is faulty. Use the instructions in these links to determine
if the component has been diagnosed as being faulty.
