Installing Firmware for the LTE Modem (Sierra EM7565).
The modem installed in our Nodegrid SR product line is the Sierra EM7565 modem. The link to download the firmware is provided below:
The commonly used carrier firmware has been circled (AT&T, Verizon, and GENERIC). These files are also available in the ZPE's Sharefile
The modem card can only carry 4 firmware files at a time, so it's best to only upload the ones that you know you will need/use. Our Nodegrid has 2 SIM slots per modem. The GENERIC driver works for most carriers, including T-Mobile, but as a precaution, we advise that you load the Nodegrid with additional firmware for future SIM changes. We want to save you the trouble or headaches in the future.
To upload these firmware, please log onto your Nodegrid's management portal and click on "Wireless Modem" (Network::Wireless Modem). Place a check next to the modem interface "Channel-A" and then the "Firmware" button will become active. Click on the "Firmware" button.
Once you click on the "Firmware" button, the window below will appear. Click on "Upgrade" and this will now open another window, which will now allow you to upload a firmware of choice.
Click on "Choose File" button below and navigate to the firmware that you had just downloaded in your laptop/PC. After you select it, click on the "Upgrade" button. This will upload and save the firmware to modem. Repeat this step for all other firmware that you need to upload.
Once the modem detects the carrier on the SIM card, it will load the correspondent firmware.
