Release Notes for 200, 300, 500, and ESW2 Series Switches Firmware Version 1.3.5.x

•

In version 1.3.5, the Flash file system was upgraded. This has implications 
when upgrading from previous releases to version 1.3.5, and when 
downgrading from 1.3.5 version to previous versions as described below. 

During the first bootup of the new version, the flash file system is upgraded. Note 
that: 

•

This process takes a few minutes. “…” progress in the Console will be 
displayed during this process (not relevant to Sx200). 

•

The syslog file is deleted during this process. 

•

The original image file is deleted. The two images on the Flash after the 
upgrade will have the same version (1.3.5). 

Before upgrading to version 1.3.5, the boot loader also needs to be updated. 
If version 1.3.5 is installed using the original boot loader, the file system will not be 
upgraded, and in the future the user will not be allowed to upgrade to versions 
higher than 1.3.5.

•

The downgrade copy operation process takes a few minutes since the file 
system needs to be converted prior to the copy operation itself. The user 
will be notified (using “…..” progress on CLI or a message on the WEB GUI) 
that the conversion process is ongoing. When the conversion process ends, 
the image download begins automatically. The device will automatically 
reboot after the copy is finished. 

Powering off the device during this process might damage the file system, in such 
case, booting up might require connecting to the device using the console cable 
(not relevant to Sx200) and loading the image file using XMODEM. 

•

After the downgrade, only downloaded image file will remain on the Flash 
(the 1.3.5 image is deleted during this process). Note that there’s no need to 
downgrade the boot file, the boot file supports both file systems. The boot 
file cannot be downgraded while version 1.3.5 is active.
