SG300 bootloader upgrade

For the new .ros I received because of a bug, they gave me a new bootloader. How do I update the bootloader?

SG300 bootloader upgrade

You have to download a SFTP / SCP server or a TFTP server onto your PC if you don't have one already.  I forget which but it's apparent on the switch when you get to choose the update method.

I downloaded a free version for the ones I mentioned from SolarWinds.  When you install the program it will install a directory, C:\TFTP-Root or C:\SFTP_Root, I have both becuase one is needed for the switch and the other something else that escapes me.  If you use something other than SolarWinds the root directory may have a different name and be in a different location but the installer should let you know so pay attention. 

Drop your .ros file into the appropriate root directory and then point your switch to that PC's IP for the update and enter the file name for the file you dropped in the folder.

SG300 bootloader upgrade

Oh, and make sure you open the program you downloaded and start the server.  The switch can't connect if the server ain't running. 

On the SFTP / SCP server there's a drop down arrow on the bottom of the window by "stopped" that give you the start option.  The TFTP server you need to click >File>Configure and start on that pop up.

Stop your server when done.

Vingele, can you help me on

Vingele, can you help me on how to upgrade Bootloader. I can see I need to do it using ssh or similar, but is there a guide somewhere?

I'm running:

Firmware 1.3.5.58

Boot Version 1.0.0.4

I guess I have to downgrade firmware, then upgrade bootloader and finally upgrade firmware to latest build. Is this correct?

I do have a CCNA, so understand networking, but never used ssh on my SG300 and never upgrade anything using CLI.

step 5: command

# copy boot tftp://192.168.1.101/sx300_boot-13506.rfb     ( all you need to do type copy boot tftp://192.168.1.101/press right button in your mouse and you will see file name show command )

I have a similar problem.

I just have one major question: how do I upgrade Bootloader. I can see I need to do it using ssh or similar, but is there a guide somewhere?

It's probably too late to

It's probably too late to help you with this answer. As of today you post has been up for 3 months+.

This may help someone else.

I upgrade an SG300-28P (Nice switch - would love a 2960-48-POE though.). This switch is in my home and works very well. I'm hoping someday they come out with a 2 PORT 10GBe uplink version :)

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.

7. After you are done - reboot the switch. It will take 2-5 minutes to finish (at least mine did) ... all my settings including Radius were preserved.... it went pretty smooth.

 

Hope this helps someone ...

Heya Waltercoria.I did find a

Heya Waltercoria.

I did find a solution.

Firstly: Internet Explorer and cisco just doesn't work well. Not even just for this forum here. This is actually what causes the most troubles for me.

I rarely ever configure using console as I only have an SG200 and an SG300 here at home, and just can't remember the commands I don't use all the time.

So. I downgraded firmware using Google Chrome.

For TFTP server, I used Open TFTP from here: http://tftp-server.sourceforge.net/
Very simple and easy to use

 

It was your step 6 I had trouble figuring out when I wrote my previous post

"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."

Walter,Your instructions

Walter,

Your instructions helped me update my SG200-26 using TFTP for both the firmware and boot loader, and the process you described worked perfectly. 

Thanks!
