Switch firmware archive (HP, Cisco, Forti..)

Hi everyone,

I'm looking to upgrade some old HP and cisco switches, but I'm stuggling to find old firmware...

If I remember correctly there was an HTTP/FTP server with a lot of old firmware for networking devices, but I can't seem to find any link anymore.

Does anyone know where I could find such archive ?

Btw, I searched archive.org with no results for now.

I'm specifically looking for firmware for this devices:

HP 2524 (J4813A)

Thanks for your help and have a nice day
