Upgrading HP J9299A HP 2520-24G VIA TFTP

The old Procurve switch line is very long in the tooth, but I run across them all the time. In this case its a 2520 switch that is in very bad need a of a firmware upgrade. I will detail where to go to get the firmware, and how to use TFTP to upload it. In my case, the web interface is having all kinds of java issues, and TFTP is just easier.

First lets get the software – it can be found at :


Next, I download the firmware for the J9299A, and it seems the latest is from 2016. I download it, put it on my TFTP server which has full network connectivity to the switch.

SSH to the switch, and run these commands

If you get the error ” SFTP must be disabled before enabling tftp. ” you will need to run the “no ip ssh filetransfer” command first before enabling tftp client.

config t
no ip ssh filetransfer — This allows TFTP, if you enable this, and use SCP or SFTP then no need for TFTP
tftp client
copy tftp flash J_15_09_0028.swi primary

It will then write this to the primary flash. Next I will tell it to boot this firmware.

boot system flash primary  РNow it will reboot with the latest firmware
