A. POST procedure 

After the power has been turned on, NetworKam 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.
