Hi all, I noticed today after setting up my battery backup for my servers that when I unplug the ups the proliant makes a clicking sound. It seems like it's coming from the psu, especially because the warning light for psu #2 goes to amber. This occurs whether I'm using a APC or CyberPower UPS. These are not server grade UPS's rather just consumer/desktop pc ones. I'm not worried about damage or anything just curiosity so please don't waste your time researching for me. I'll attach a video.
