Power On Self Test (POST)
After the power has been turned on, Video Server will perform a self-diagnostic to detect any
possible hardware defects. The CONNECT (LED 2) and SERIAL (LED 3) LEDs will blink
during the POST, and will keep blinking until the POST completes successfully, or a fatal error is
detected. If either status LED indicator is dim to start off with, the LED may be broken.
When certain fatal errors occur, LED2 and LED3 blink in a particular way to indicate the type of
failure, as described in the following table.

Frequently Asked Questions
Q: Why can’t I see the Video Server in the installer after rebooting?
A: The installer is only used to install the IP address of the Video Server. If the IP address is fixed
by checking the option in the installer, the Video Server will no longer appear in the installer.
Q: Why can’t I connect the Video Server after rebooting?
A: If the IP address is not fixed, Video Server will always wait for the installing command to
provide a valid IP address. This means that the previous IP address will not be used if the
option in the installer is not checked; or the option in the network configuration is not cleared.
The benefit of waiting for a valid IP address by default is that administrators can find the Video
Server in the installer to prevent IP conflict. As long as the IP address is confirmed, we suggest
fixing the IP address to make Video Server automatically start up whenever regaining power.
Q: What if I forget my password?
A: Every access to Video Server needs authentication. If you are not a permitted user, you may
view the images or control the camera as long as the demo account is opened. The demo
account user may use username as “demo” without any password to access limited features. If
you are one of the managed users, you must ask the administrators for the password in the first
time. If you are the administrator, there is no way to recover the root password. The only way
to regain access to Video Server is to restore the factory settings and reinstall it.
