I have an APC SUA2200RMXLs that is giving me issues. I just picked it up with theAP9619 Network Management card in it. It was working at first, but I couldn't use a password longer that 11 characters, so I updated the firmware on the UPS to 3.7.2, and the management card to 3.7.3. this fixed the password issue, but now when I log on to the management page, most tabs work except for everything under the UPS tab. I have e message on each section under UPS saying that the UPS is disconnected. I can not communicate with the UPS, even when unplugging the UPS, I get no alerts. I have searched to find a way to roll back my firmware if that will fix the issue. Can someone point me in a direction to try to resolve this. Remote control of the UPS is the most important feature that I got this for.
