Each time Video Server starts; it will perform a Power-On Self Test, abbreviated as POST hereafter, to
examine every hardware module. As soon as the administrator plugs in the power adapter, both LEDs
under the network LED will flash one by one until the POST is done. If any module fails, both LEDs will
indicate to the users the error according to the pattern listed in Appendix A. If the result is good, both
LEDs will turn off for a while and then follows the pattern below. Network interface depends on the
peripherals including Ethernet UTP cable, modem or null modem cable. If the Ethernet cable between the
Video Server and Ethernet hub is good, Video Server will choose the Ethernet network. If Ethernet is
unavailable but a operational modem is connected, the network interface will be PPP with modem. If
either of the above is not the case, The Video Server will try the interface of PPP with null modem.

Restore button
There is a button hidden in the box for restoring the system factory default settings. When the system fails
to install or operates abnormally, use the included assistant stick in the package and follow the following
procedures to reset the system back to its original status.
Poke the assistant stick into the hole to press down on the restore button. Restart the system by
unplugging and re-plugging the power jack. While keeping the button pressed, the system will perform
POST twice rather than the usual once, which can be observed from the flashing LEDs. After the system
flashes the LEDs for the second time, withdraw the stick to release the button. The system will have
restored factory default settings at that moment.
