For the best Wake-on-LAN experience with an APC UPS:
Best practices for APC UPS systems involve utilizing BIOS/UEFI "Restore on AC Power Loss" settings for reliable post-outage recovery rather than relying on Wake-on-LAN (WoL) packets. While WoL can be triggered via APC PowerChute scripts or Network Management Cards (NMC), configuring the BIOS to "Always On" or "Last State" provides the most consistent automation.

: If the UPS stays on, it continues to provide power to network switches and routers, which are necessary for WoL to work if you need to wake a machine manually later. For the best Wake-on-LAN experience with an APC
You have three options:
Not all APC UPS units support WoL passthrough. For best results, use a Smart-UPS or Back-UPS Pro with a USB or network management card (AP9630/AP9631). These can send a “power restored” signal that triggers WoL. Solved: Wake On LAN (WOL) behind a Smart-UPS
To utilize Wake-on-LAN effectively with APC hardware, you need a "Packet Forwarder." This is a device that remains powered by the UPS even during outages. The best candidates are:
Plug your PC/NAS into a Surge Protection Only outlet if you only need WoL. Wait—this is counter-intuitive. If you do this, the PC loses power instantly during an outage. That is bad. Correction: You need the Battery + Surge outlet, but you must configure the "Shutdown Delay" (see below).
