Integrating APC UPS with ESXi: A Smooth Experience

I recently had the opportunity to integrate my APC UPS with my ESXi server, and I wanted to share my experience with the community. The setup involved using the APC Shutdown appliance on my ESXi 7.0 server, which allowed me to configure a threshold time for initiating a shutdown command to my virtual machines. This feature worked seamlessly, ensuring that my VMs powered down gracefully during a power outage.

However, I encountered a question that I thought others might find interesting. I wondered how to initiate a start command for the ESXi server from the APC when the power was restored while the APC was still on battery power. Initially, I noticed that the APC did not send a power command to the ESXi server in this scenario. After some research and testing, I discovered that this functionality works as intended when the power is restored after the battery is depleted. This means that the APC will send a power command to the ESXi server once the power is back, ensuring a smooth restart process.

This experience highlighted the importance of understanding the specific use cases and configurations of APC UPS devices. It also underscored the value of community forums like this one, where users can share their experiences and troubleshoot issues together. If anyone has further questions or insights about APC UPS integration, I’d be happy to discuss them further!
