The firmware is the program that controls the operation and functionality of the switch. It is the combination of software and hardware that has program code and data stored in it in order for the device to function.
Upgrading the firmware improves the performance of the device, which could provide enhanced security, new features, and bug fixes. This process is also necessary if you encounter the following:
- Frequent network disconnection or intermittent connection using the switch
- Slow connection
The objective of this document is to show you how to upgrade the firmware on your switch.
Applicable Devices | Software Version
Backup your configuration prior to upgrading the firmware. You can do this by navigating to Administration > File Management > File Operations in the menu. Download a copy of the running configuration to your PC. It is not recommended to do a firmware upgrade of your device remotely.
Upgrade Firmware on the Switch
Upgrade the Firmware
Before you proceed, make sure to download first the latest firmware of your switch from the appropriate link above. As an alternative, you can follow the steps in How to Download and Upgrade Firmware on any Device. If you prefer to use the Command Line Interface (CLI) to upgrade firmware, select the toggle button at the top.
Log in to the web-based utility of the switch and choose Administration > File Management > Firmware Operations.
On the File Operations page:
- Click the Update Firmware radio button as the Operation Type.
- Click the HTTP/HTTPS radio button as the Copy Method.
- For the File Name, click Choose File and locate the previously downloaded firmware file from your computer.
Choose USB if you would like to transfer firmware to the switch using a USB flash drive.
Choose the file then click Open.
Reboot the Switch
For the upgraded firmware version to be applied, the switch must be rebooted.
Choose Administration > Reboot.
On this page, enter the following:
- Ensure the default of Immediate is selected.
- (Optional) Check the Restore to Factory Defaults or Clear Startup Configuration File check boxes if desired. With either option chosen, the switch essentially performs a factory default reset since both the running and startup configurations will be deleted upon reboot.
- Click Reboot.
The switch will then reboot. This process may take a few minutes.
Verify the New Firmware
To verify if the new firmware has been successfully upgraded:
Choose Administration > File Management > Firmware Operations.
Check the Active Firmware Version area to verify if the updated firmware has been successfully uploaded to the switch.
Nice work! You should now have successfully upgraded the firmware of your switch.
