Step by step process for updating gateway firmware
There may be a time when it makes sensor to update the your gateways firmware. Please note that the Ethernet gateway has two microprocessors and each microprocessor has firmware on it. One microprocessor handles the radio operations for interaction with the sensors. This firmware is NOT upgradable over the air!
The upgrade described here is for the firmware on the microprocessor responsible for interacting with the server and those types of operations.
If using iMonnit Premier or Basic (Express):
Keep in mind that updating the gateway will remove any and all configurations you have made to the gateway settings, including Static IP Addresses and interface settings.
If using Enterprise or MINE:
You will have to point the gateway back to iMonnit to apply the update.
Note: Updating the gateway will reset to factory defaults. This includes the heartbeats. Factory heartbeats for an Ethernet gateway are 5 minutes and for a Cellular gateway are 60 minutes. For the Ethernet gateway, if there is a static IP Address or similar setting, it will revert to DHCP. It will then need to be taken to a network with DHCP to be configured with the static IP Address again.
After you press the upgrade link the server has to wait until the gateway checks in (see your heartbeat setting). Then the upgrade process takes about 30 seconds to download the new firmware and then it will reboot and be ready to go.
