Power On Self Test (POST)
Each Module automatically performs a self-diagnostics when inserted into the
system Card-cage. These tests determine that the unit is a) correctly installed in the
Card-cage and b) not damaged in transit.
• All six of the LED’s on the front panel will flash 3 times
• If the LED’s do NOT flash three times, then remove the module, check the power
source, and re-insert the module, (See Installation Instructions).
• If the card is “OK” the LED’s will continue normally. (See Normal Operation)
• If there is a fault, then the Red Fault LED will remain on. If this occurs, contact
your KAVAL WIRELESS TECHNOLOGIES Service Representative, (See
Warranty / RMA Procedures).
The Power On Self Test is Not an RF test, it only verifies that there is power to
the unit and that the logical circuitry is functioning.
Fault Indications
Each Module continuously performs internal diagnostics. If a problem is detected it
will activate its Red Fault LED and Fault Relay. Faults detected include...
• Over Temperature
• Misc. Internal Faults
Detailed Faults are detected by the optional Gateway Module. Details may also be
determined via the Module's Control Port Connector and an RS232 connected
Terminal Emulator using the LIST command.
