Just to test, I reset an SEB back to default. Pressed the reset button 15 times and the CHK light went out. Then I uploaded a test ASP and Database to the unit and the CHK light came on. Then I reset the SEB again, pressing the reset button 15 times and the CHK light went out.
So the answer to the $25,000.00 question, is YES, the CHK light is supposed to be on if the modem is functioning properly.
I guess it's been a while since we normally put in the Netpath boxes now and I needed to see for myself.
So, under the SYSTEM block: PWR/CHK/RDY should be on if everything is working fine, and if there is no Database or ASP file loaded then the CHK light will be off adn PWR and RDY light will be on.
Hope this clears it all up.
