How do I figure out which device
the fault LEDs are referring to
on the 8400 Server?

1. Power - steady green when power is on, flashing green in sleep-mode.

2. LAN Activity - green when network connection is active.

3. HDD Activity - Green when hard disk is active.

4. Power Fault - blinking yellow when power supply fault occurs.

5. Fan Fault - Steady yellow when the computer has a critical, non-recoverable cooling problem, and blinking yellow when system has a non-critical, over-temperature or low-fan-speed condition.

6. Power button - turns the computer on and off. It also enables sleep-mode in some operating systems.

7. Sleep button - initiates sleep mode to conserve power.

8. Reset button - restarts a computer that has stopped responding.
