Troubleshooting and Recovery Operations When
Powering On the System
Green LED Is Not Lit After POSTs Finish
It can take several minutes for the green LEDs on all system components to light:
1. Check that fans are turning and that the AC power cords and power-on cables are
properly connected.
2. Wait for the POSTs to finish. It might take as long as 10 minutes for all system
components.
3. If the green LEDs still do not light:
a. Check that power-on cables are properly connected and repeat the power-on
procedure.
b. If one green LED still does not light, a system component might have failed its
POST.
4. If you cannot determine the cause of the problem, contact your service provider.
