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.
