Power supply indicators
Each power supply has LEDs that indicates status.
Interpret the power supply LEDs as follows:
Another indicator of power supply operation is the audible fan noise. If a power cable is connected to either power supply, the fan should stay on continuously on both power supplies. This is the case even if the K2 Summit system is shut down or restarting via the standby switch or the Windows operating system.
The Service LED on the front of the K2 Summit system also indicates power supply status.
If the power source and the power cord are OK yet there is still a power supply problem, the status lights on the power supply indicate the problem.
