Hey everyone! I'm looking for some guidance as I'm not an electrical expert. At my workplace, we have a server rack that's powered by two APC Smart UPS 1500 units. Occasionally, the servers reboot unexpectedly when the UPS units go down, although by the time we check, they seem to be functioning normally again. This has happened a couple of times now with both UPS units simultaneously. While other UPS units are running fine, it raises a question about whether there's an issue with the plugs since both UPSes are affected. What steps do you recommend for diagnosing and fixing this issue?

When you mention the UPS units are down, are they just switching to battery mode, or are they actually draining? If they pass to battery but run out, that could explain the reboot. Also, do you have email alerts set up on these units? It might help to understand the issue better. Testing them on a different circuit could also isolate the problem. And do the servers have dual power supplies connected to the two UPSes?
Definitely check the logs first; it could indicate a problem with the circuit itself. Better to find out early than too late!
Start by checking the UPS logs. They often provide clues about what might be going wrong. If you skip this step, it's like trying to guess the answer without any information!
Totally agree! Logs are crucial; it's the first place to look for issues.
Honestly, those APC Smart UPS 1500s might not be the best choice for your rack. Make sure they’re plugged into different circuits instead of the same outlet. You could also be experiencing broader power issues. It might be a smart move to get an electrician in to ensure everything is wired correctly to avoid any hazards like fire. Going forward, switching to proper rack-mounted UPS systems would probably be a better long-term solution.
1. It seems like they lost power completely; that’s what I was told.
2. No email alerts are set up since they only work with a cloud service we don’t use.
3. Yes, there’s redundancy in the servers' power supplies.
