A. Troubleshooting

A.1 Power-On-Self-Test

After the power has been turned on, Video Server will perform a self-diagnostic to detect any possible hardware defects. If the power indicator is dim at the beginning, the system fails to proceed further without power. While the POST is proceeding, the status LED indicators will keep blinking interchanged until finished or any fatal error happens. If either status LED indicator is dim at the beginning, the LED may be broken.

Any possible fatal error has a special pattern shown in the following table. LED1 is the one below power indicator and LED2 is the lowest one.
