My Cisco appliance was showing the amber color exclamation point. While I did the typical show and tech commands I could not find anything wrong with the box. I checked the Light Path Diagnostics on the appliance, it quickly pointed out a power supply problem.

Remind button: This button places the system-error LED on the front panel into Remind mode. In Remind mode, the system-error LED flashes once every 2 seconds until the problem is corrected, the NCS appliance is restarted, or a new problem occurs.
By placing the system-error LED indicator in Remind mode, you acknowledge that you are aware of the last failure but will not take immediate action to correct the problem.
•NMI button: This button is used to force a nonmaskable interrupt to the microprocessor. This button is not currently used by the Cisco Prime Network Control System appliance. Press this button only when directed by the Cisco TAC personnel.
•Checkpoint code display: This display provides a checkpoint code that indicates the point at which the system stopped during the boot block and POST. A checkpoint code is either a byte or a word value that is produced by UEFI. The display does not provide error codes or suggest components to be replaced.
•Reset button: Press this button to reset the NCS appliance and run the power-on self-test (POST). You might have to use a pen or the end of a straightened paper clip to press the button. The Reset button is in the lower-right corner of the light path diagnostics panel.
