How to upgrade Firmware on cisco SG switch

Postby blin » Fri Nov 14, 2014 5:26 pm

1. Download the firmware from Cisco.
2. Login Cisco Switch and navigate to Administration>File management>Upgrade/Backup Firmware.
3. Upload the firmware two files. *.rfb and ros.
Note: There are two firmware images stored on the device. One of the images is identified as the active image
and other image is identified as the inactive image.
When you upgrade the firmware, the new image always replaces the image identified as the inactive image.
Even after uploading new firmware on the device, the device continues to boot by using the active image
(the old version) until you change the status of the new image to be the active image
