Update Firmware

Update the firmware of one or more devices using Lantronix Provisioning Manager.

Firmware Update Preparation

Do the following before performing the firmware update procedure:

  • Configure SFTP/FTP Server Settings if working with OOB devices.
    • If using an external SFTP/FTP server, store the firmware file on the server in the folder specified in Path in Server Settings.
    • Obtain the MD checksum of the firmware file if working with OOB devices.
  • Ensure you have the correct and valid firmware file.

Firmware Update Procedure

To update the firmware of one or more devices:

  1. Click Provision on the side menu.
  2. Select one or more devices to update. They must all be the same type of device (for example, all SLB devices).
  3. Click Update > Firmware.
  4. For OOB devices, choose whether to reboot the device after the update using the checkbox.
  5. If using the SFTP server built in to LPM or working with IoT devices, click Upload Firmware File and select the firmware file. If using an external SFTP/FTP server, type or paste the name of the firmware file in the field.
  6. If the Enter Firmware file key field is present, provide the MD checksum of the firmware file. This field will not appear for some devices.
  7. Click Update or press Enter to begin the update. While the device is rebooting, connectivity is disrupted.

Check the Operation Status and Progress columns to see the progress of the firmware upgrade.

Note

SLC, SLB, and EMG devices have two boot banks: an active bank and an inactive bank. A firmware upgrade applies to the inactive bank. After updating, the device reboots with the newly updated bank active.
