Upgrade instructions

You can upgrade your FortiExtender to the FortiExtender 4.2.6 OS image from FortiExtender 4.0 or later. Your FEX-201E and/or FEX-211E devices may not be loaded with the latest modem firmware when shipped. To ensure their optimal performance, you MUST upgrade their modem firmware with the firmware package (preferably version 19.0.0 or later) specific to your wireless service provider before putting them to use.

Firmware upgrade procedures

You can upgrade the modem firmware package in its entirety using the FOS CLI, or the FortiExtender OS GUI or CLI. You can also upgrade a specific piece of firmware or PRI file (if you are an experienced professional user).

Modem firmware packages with .out extensions can be downloaded and unzipped from Fortinet Support website. Your unzipped package contains either the Sierra LTE-A EM7455 or the Sierra LTE-A PRO EM7565 modem firmware, which consists of two types of files:

• A PRI file with the filename extension ".nvu"
• A firmware file with the filename extension ".cwe"

You must flash both files onto the modem to connect to the wireless service provider of your choice.

Upgrade via the FortiExtender (device) GUI:

1. Log into your FortiExtender.
2. On the navigation bar on the left, click Settings.
3. From the top of the page, select Firmware.
4. Select Extender Upgrade > Local.

When connected to the Internet, FortiExtender is able to pull the OS images and modem firmware directly from FortiExtender Cloud, irrespective of its deployment status.
