Hi,

How do I upgrade the bootloader  on a Cisco SG200-50 GigaBit Smart Switch ?

Short answer is you need to use a tftp server.  Search the forum for many instructions.  Here is one: https://supportforums.cisco.com/discussion/11953536/sg300-bootloader-upgrade

Using TFTP Server:See below steps,

1. Make a backup of your config (just in case ... and CYA)

1. I upgraded the firmware using the web interface (.ros) file.

2. Apply or Activate and reboot

3. Your switch should reboot just fine.

4. To install the boot load (.rfb) you must use a TFTP server ...not sure why this is so.

If you don't have one - I suggest using TFTPF32 or 64bit version. I don't like the solarwind goons.

5. Hopefully you have some past history using FTP. It's really simple just stick the file into the upload/download folder of the TFTP server and you should be good to go.

6. Cisco SG WEB interface > Administration>File Managment> TFTP .... when you select TFTP the radio button for the "BOOT" fw is now available. Just type in the name of the file and it should load the boot firmware.

I wouldn't reboot in between and I never have myself. It might not even be a good idea because you want the new boot to be properly support the new firmware. I load both, set active image to new one, copy run start and then reload.
