Appendix
A. Self-test
Following switch-on, the video server runs a diagnostic self-test to detect potential hardware faults. As the self-test
continues, the LEDs flash alternately until the test is finished or until a serious error occurs.
The following table lists possible serious errors with their patterns. If the self-test reveals no errors, the two LEDs
switch off briefly and then light according to the selected interface. If the Ethernet is available, LED2 flashes. If a
modem is available, LED2 flashes and LED3 lights up. If the null modem cable supplied is connected, both LEDs
light up. Following connection, LED2 flashes.
LED pattern following self-
test???
LED2 and LED3 flash simultaneously
LED2 ON and LED3 OFF
LED2 OFF and LED3 ON
LED2 ON and LED3 ON
LED2 flashes and LED3 ON
LED2 ON and LED3 flashes
A fault in the Ethernet interface can refer not only to components on the PCB but also to the Ethernet
cable or Ethernet connection.
B. Frequently asked questions (FAQ)
F. What do I do if I forget my password?
A. Every access to the video server camera requires an authentication. If you are one of the managing users, ask
your administrator for your password. If you are the administrator, there is no way of reactivating the password. The
only way of accessing the video server is to press the reset button to restore the factory-set parameters and then
reconfigure the system.
F. Why does no video appear from the video server following authentication?
A. This problem can be caused by various factors:
1. If you have just installed the video server and see no video, check the video modulation on the
configuration page.
2. If the video server is correctly installed and you are accessing it for the first time via the Internet Explorer,
reduce the security level of the Internet Explorer to enable the installation of the plug-ins.
3. If this problem recurs, the users are possibly working at a higher level than is permitted by the system.
