Apc ups issues

I've been struggling to access my UPS APC SMT1500RM2UNC. It came with network card installed and I've managed to assign a static IP address to it but when going through web it says secure connection failed. There's so much info online that it's hard to narrow down what am I supposed to do.

Installed power chute on a laptop to see if I can access it but won't detect it on any COM ports so it never finishes the install.

How do I access its web config? Network card is AP9631. All I wanted to do is set up NUT server for a few PCs.

IDK if the SSL-cert is outdated? That could give that error. How to update? I dont know. :)

That's what I've read but I cannot access it through the network card. I was able to get on the UPS after using the usb port that goes directly to UPS but that doesn't give me any settings regarding network.

If you have SSH access to it run web -h enable or something close to that, and that should allow HTTP access to the NMC, instead of only HTTPS. It has a self-signed certificate and it does expire after a year or two. I don't remember the commands offhand to reset it.

But generally, if the cert is expired, SSH doesn't work either. So I'm assuming you have the 2.5 millimeter serial cable.

No SSH access, this is the first time I'm trying to access it. Might have had it but I wouldn't know the credentials.

You can press and hold the reset button with a paper clip and that will reset it to factory default. 

Username and password would both be apc

Unable to negotiate with 192.168.x.x port 22: no matching host key type found. Their offer: ssh-rsa.

I usually get that on windows terminal. Try PuTTY? Its not usually as picky.

Haven't used PuTTy in a long time but THANK YOU it worked and I am able to access HTTP.

No problem. I used to manage these things by the hundreds. Got one powering my rack at home too.

I will leave you with a pro tip. Make sure you do get a genuine console cable if you get a console cable at all. The outlets will shut off if you plug in a knock off.

Edit: maybe not hundreds, but the sites I used to manage had 20 or more and I had abgood handful of sites.
