Important notes:
- We provide new favorite firmware with suffix "Lite". It reduces the maximum VLAN count from 4093 to 255 and the memory utilization will be lower than the normal version. If you have no requirement for 255 and more VLANs, you might consider this one.
- Please check your configuration before you update to the Lite firmware version. VLAN configuration will be lost if there are more than 255 defined VLANs.
About Switch Firmware:
Given the large variety of models and different methods for upgrading the switch, if you wish to apply this package, we recommend that you read and understand the installation steps before you install a new firmware, even if you are a power user.
Usually the update procedure isn't much of a hassle as manufacturers try to make it as simple as possible; however, there are cases that are exceptions to this rule. First off, go to the system information page of the switch to check that the currently installed version isn't either newer or matching this release.
Applying a new firmware can decrease the security vulnerabilities, enhance overall performance and compatibility, improve various power management functions, resolve different errors, and add support for newly developed technologies and protocols.
It is recommended that you perform this step in a steady power environment such as the one ensured by a UPS unit, and that you don't interrupt the upgrade in any way, because this might cause the switch to malfunction.
That being said, click the download button, get and apply the new version, and check back with our website constantly to stay up to speed with the latest releases.
