Here is my standard disclaimer: I’m not responsible for bricked, broken, or non-functioning hardware. Upgrading firmware is a very delicate process which can result in completely useless hardware if done incorrectly.
I recently ran into a problem where I needed to upgrade the firmware in my HP Procurve 2524 switch. The HP documentation doesn’t clearly state how to upgrade the firmware, just that you can do it via telnet and with an TFTP server… thanks HP.
To upgrade the firmware of your HP switch via TFTP you’ll need to download Solarwinds’ free TFTP server from http://www.solarwinds.com/products/freetools/free_tftp_server.aspx
Registration is NOT required and installation is a snap. Follow the prompts to install and bind the TFTP server to your IP address. FYI: the TFTP server will create a folder in your C: root (granted you are running a Windows-based operating system) in which you’ll need to place the switch firmware.
You’ll also need to download your switch’s firmware. You can probably find it here: http://www.procurve.com/customercare/support/software/switches.htm
Once you have the TFTP server installed and the firmware downloaded, drop the firmware (the .swi file) in the TFTP server’s folder on the root drive (for example C:\TFTP-root\firmware.swi).
Open up a command prompt and telnet into the switch.

You’ll be prompted for your username and password. If you reset (or initially configured) your switch via web interface, this will be your username and password that you configured.

Once your at the switch’s menu type “menu”

Press “7″ on your keyboard or scroll down to “Download OS”

Select “TFTP” from the menu, enter the TFTP server address (I’m running the TFTP server on my actual server so, in my case, the IP would be 192.168.2.2), and enter the firmware filename (your_firmware_name.swi).

If you haven’t started your TFTP server right click on the icon near the clock and select “start” (sorry, I have no image). Once the server service is running you can safely initiate the transfer.

The file transfer should begin in the telnet window. Wait for the transfer to complete. Once finished your switch will be running with the most recent firmware.

Enjoy!
