Update modem firmware by using a local firmware file
You can update your modem firmware by uploading a modem firmware file to your Connect IT 16/48
device. Firmware should be uploaded to /opt/MODEM_MODEL/Custom_Firmware, for example,
/opt/LM940/Custom_Firmware. Modem firmware can be downloaded from Digi at
https://ftp1.digi.com/support/firmware/dal/carrier_firmware/. See Use the scp command for
information about uploading files to the Connect IT 16/48 device.
1. Log into the Connect IT 16/48 command line as a user with Admin access.
Depending on your device configuration, you may be presented with an Access selection
menu. Type admin to access the Admin CLI.
