How to upgrade PDU 7921 firmware?

[smallfish01]

Hello,

I have APC 7921 PDU,and I'd like to control power from remote, for example I need ssh to PDU and running command to On/Off outlet, but now when I telnet/ssh to PDU, only have control console and cannot running command.

My PDU APP version: 3.7.4, Network Management Card AOS version: 3.7.4

I'd like to upgrade the firmware from official website, but nothing found.

Hello,

The AP7921 has been discontinued for some time, but we released AOS v394 / RPDU v393 a short while ago to address the Ripple20/Treck vulnerabilities. You can get that version from our public KB here: https://www.apc.com/us/en/faqs/FA410359/

Or from our public Box link here: https://schneider-electric.app.box.com/file/830448401299?s=5mmbnnzlbijoqw9qchltf1n86kdg3tfg

Thanks for your replied, I have upgraded the AOS.

Another question, how can I control PDU from ssh? Such as to running command to On/Off outlet, and now if I ssh to PDU only can type two characters, cannot type any command like "help".

Older PDU's used a special scripting interface, we have a guide here: https://www.apc.com/eg/en/faqs/FA156163/
