CyberPower UPS and Management Card RCCARD100 Review

After purchasing the CyberPower CP1500PFCLCD UPS, I opted to purchase the RCCARD100 so that I could manage the UPS on the network. Unfortunately, the card did not work in the CP1500PFCLCD UPS. There were no lights at all while inserted, and no lights when an ethernet cable was plugged in from a switch.

After digging further online, I didn’t find much about troubleshooting. But I did see lots of people talking about how this management card was cloud-only and required a subscription. I didn’t waste any time and returned it.

I’ll keep the UPS for now, the next UPS will be an Eaton or APC with a real management card. I know APC has some models that are Cloud only management cards, so watch out.

OVH Public Cloud CentOS 7 Change Hostname

If you’ve tried to change the hostname on your OVH public cloud instance running CentOS 7, you may have had issues with it persisting after reboot.

Took me way to long to find this solution, but someone had already spent way too much time figuring it out.

This GitHub Gist explains it all

Basically you need to edit /etc/cloud/cloud.cfg and add “preserve_hostname: true” and then set your hostname using hostnamectl.

hostnamectl –transient set-hostname
hostnamectl –static set-hostname

Hope that helps and thank zmjwong!
