Appendix

A. POST procedure
After the power has been turned on, Video Server will perform a self-diagnostic to locate any
possible hardware defects. If the power indicator is dim at the beginning, the power fails to
proceed further. 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. LED2 is the one
below the network indicator and LED3 is the lowest one. If the POST is successful, status LED
indicators will both shut off for a while and then light depending on the chosen network interface.
If Ethernet is available, LED2 will flash like a heartbeat after network installation is done.
Otherwise if modem is available, LED2 will flash alike to indicate listening for dial-in
connection while LED3 is lit. If the included null modem cable is connected, both LEDs will
stay on and then LED2 will start flashing after the connection from the PC is opened for
configuration and LED3 stays lit.
