To summarize the combination of steps that I was able to utilize to get to the state I am now, in case anyone in future runs into this same issue, here is everything in order, as best I can remember. Regaining access to the devices web user interface without using SSL: I hope this helps some of you!
Hoping for some suggestions. I've become the senior IT admin recently after the last of the old crew moved on and recently we had a power outage knock out all of our servers due to the batteries in one of our two old Dell UPS 4200W backups failing. I recommended replacing the unit with newer, more efficient and up to date equipment, but the plan was made to simply replace all the batteries in the current unit and try to limp along with it until next year if possible. I got the new batteries installed and they are now charging and everything appears to be reporting ok, however, the LCD is still flashing the failed battery test warning. Even though the new batteries have reached 100% charge, have been running for over 72 hours, and there is currently a 13% load being pulled from the unit, the automated battery test does not appear to be running to reset the warning. I do not see any way from the front-panel LCD controls, nor any terminal menu options via serial console connection to allow me to kick off a manual battery test. My biggest headache at the moment though, is that my last option to try and manage these ancient units appears to be through the web management interface. However, being as old as they are, no modern browser will allow me to establish a connection to the interface due to outdated and unsupported SSL protocol requirements. Is there ANY way that anyone knows that I can circumvent or disable the SSL on the NMC for these units so that I can manage them? Or are they truly too old at this point to be considered able to be supported? I can pull the serial numbers and current config data from them using the Dell MUMC, but cannot use that to push firmware updates or changes to them. (All firmware versions I have tried to download say they are unsupported, and honestly, on one of them I have no way of knowing what they changed the login credentials to.) Thanks for any insight you can give!
