a.POWER: power indicator

b.CONNECT: checks if the Video Server is alive

c.SERIAL: checks if the RS-232/485 COM ports are in use

As soon as the administrator plugs in the power connector, both the CONNECT and SERIAL LED’s will flash, one by one, until the diagnosis is finished. If the result is good, these 2 LEDs will turn off momentarily, and then follow the pattern shown in the table below. If any of the modules fails, refer to Chapter 7, Troubleshooting, under Power On Self Test for the error pattern, and then follow the troubleshooting procedures. If the system still does not operate normally, please contact your reseller for technical service.
