Figure 13. The LEDs on the system board
The server is designed so that LEDs remain lit when the server is connected to an ac power source but is not
turned on, provided that the power supply is operating correctly. This feature helps you to isolate the
problem when the operating system is shut down.
Note: When you disconnect the power source from the server, you lose the ability to view the LEDs because
the LEDs are not lit when the power source is removed. Before you disconnect the power source, make a
note of which LEDs are lit, including the LEDs that are lit on the operation information panel and LEDs inside
the server on the system board.
