In our previous products the SIM door interlock was a hard switch that removed all power from the router (and modem) if the door was even opened or off. Removing power would be sudden and we had no way to prepare for it, which leaves a small chance of bricking the modem or router. Then if the SIM door wasn’t replaced there was an obvious issue that needed to be addressed immediately.
Our new SIM door interlock is much smarter as it is connected to a GPIO that our Netcloud OS can read to trigger a graceful shutdown of the modem only. This removes the remote risk of bricking router and/or modem.
An unintended consequence is that if the SIM door is off the router appears to boot and/or be working - only the modem will not boot and begin working.
