I’ve installed an APC BX950MI-GR and connected it to my Proxmox server via USB.
It works: it turns off the server after x minutes after the power loss and it gets turned off by the command upsdrvctl shutdown, when the powers come back on, the UPS turns on and so does the server.
The problem is if the power comes back after the server receive the power off signal and before the UPS powers off, in this case the UPS simply goes back in the normal state and the server…stays off.
How can I turn it back on?
Thanks!
I did think about that option, but the onboard NIC is connected to the ONT (fiber connection) and the SFP+ is off when the server is off so it can’t receive WOL packets. By the way, thanks.
If you’ve got SFP+ onboard it sounds like you have a relatively serious server. Does it have IPMI? You could have a low power device like a Pi issue and IPMI command to power on.
Negative, it’s “just” an HP Elitebook with a PCIe SFP+ board.
You have no local network access to it at all? (WOL will work across the subnet, you don’t need to connect directly to it)
If genuinely not (and I’d be surprised if that is the case) add another nic of any sort (cheap) for WOL, or use something like Switchbot?
Only through SFP+ I think that the only option would be to add a second NiC. Thanks!
Can you add a second NIC? Should be able to find a Gigabit one for less than $15 or a 2.5Gbps one for $25-40.
