Open a web browser and enter the IP address of the switch in the address bar 
(192.168.1.254).

 The HTTP firmware recovery features supports the following browsers:

•

Firefox 3.0 and later versions

•

Internet Explorer 6 and later versions

A Firmware Recovery page displays. No authentication is required.

The web page displays the PIC VID (product ID and vendor ID), serial number, and 
MAC Address of the switch. 

Select Browse and select a valid firmware image to download. 

A progress bar appears while the file is downloading. The following message 
appears upon a successful download:

The file selected by administrator is downloaded to RAM and is validated for 
following conditions:

•

The CRC of the file is good.

•

The STK file is built for this platform.

•

The STK file size is within the partition limits (4.5 MB is reserved for this file).

If these conditions are met, the file is written to Flash memory and the system is 
rebooted using the new firmware. 

If any of these checks fail, the image is not written to Flash memory and the 
recovery process is stopped. You can restart the recovery process with a correct 
image file.

If the transfer is aborted because the browser window is refreshed or closed, the 
session is cleared and the session times out immediately. If the transfer is aborted 
because the network is unreachable, the session times out after 45 seconds. After 
the session times out, you can begin the recovery process again.
