I am unable to locate firmware for GS1920-48 (v1).
I was able to locate and download it from Zyxel website last month but today when I search it is only showing firmware for v2 switches. (https://www.zyxel.com/us/en/support/download_landing.shtml)
Where can I download the latest firmware for GS1920-48?

    Hi @p4_greg,

    Welcome to Zyxel Community!

    Nice vision! We actually cleared some End of Life products from our Download Library since we are no longer sustain EOL products.
    I will send you the latest firmware version V4.50(AANZ.3)C0 of GS1920-48v1 via private message.  :)

  • Hello I need an earlier firmware too, I upgraded some switches to V4.50(AAOA.3) for a GS1920-48HP (v1) last month and now ZON is unable to communicate with them. The other switches on firmware V4.50(AAOA.2) work just fine with ZON still, can you let me have a link for V4.50(AAOA.2) please?

    Hi @Zyxel_Adam  could you help me? I have the same problem that you solved on another request. I have this switch 1920-24HP with firmware 4.10. I want to upgrade it to the 4.70 but I can't do it directly as I have to upgrade it step by step with the older firmwares. I can't find them anywhere. Could you help me please? Thank you very much!!!
