Upgrading an LTE Modem
Context
When the device uses the 3G, LTE, or 5G card and the modem firmware version is earlier than the latest version, the 3G, LTE, or 5G link may be abnormal and services may be affected. When such a fault occurs, you are advised to upgrade the modem firmware.
After the modem firmware is upgraded, only the modem restarts. Exercise caution when performing this operation.
The following procedure uses the LTE Modem EC25 as an example.
Procedure
- Check the current versions of the device and modem.Run the display device command in any view to check the slot and board information.

If the version in the Modem Firmware Version field is earlier than that listed in Table 12-4, go to the next step.
- Obtain the latest software and upload it to the device.
- Upgrade the modem.
To upgrade the firmware of the LTE modem, run the module-upgrade [ transport-dcm ] slot slot-id module module-id directory command in the diagnostic view.
To upgrade the modem on an interface card, run the module-upgrade transport-dcm slot slot-id module module-id directory command. The upgrade file name of an interface card is the complete upgrade file name (with the file name extension .zip) without flash:/.
To upgrade the modem on an LTE-capable device, run the module-upgrade slot slot-id module module-id directory command. The upgrade file name of an SRU contains flash:/ and the complete upgrade file name (with the file name extension .zip).
The value of slot-id can be obtained from the Slot field in the display device command output. The value of module-id is fixed at 0.

- Check whether the modem firmware is upgraded successfully.
Run the display Cellular hardware command in any view to check the Modem Firmware Version field to determine whether the modem is upgraded successfully.
