Title: Optimizing Wake-on-LAN with APC UPS for Resilient Remote Power Management

: Once utility power returns and the UPS battery reaches a safe threshold, the UPS resumes outputting power. The server detects this new AC flow and automatically boots without needing a magic packet. Schneider Electric Community Implementing Wake-on-LAN (WOL) with APC

1. Use a dedicated network: Use a dedicated network for WOL to prevent interference from other network traffic.
2. Configure BIOS settings: Ensure that the server or device's BIOS settings have WOL enabled.
3. Use a static IP address: Assign a static IP address to the APC UPS device to ensure reliable connectivity.
4. Test WOL: Test the WOL functionality to ensure it's working correctly.

| Problem | Cause | Best Fix | |---------|-------|----------| | Server won’t wake after UPS shutdown | NIC lost WoL config in S5 | Use Intel/Broadcom NIC; disable "Energy Efficient Ethernet" | | APC cuts USB power before WoL works | USB serial chip depowers NIC | Switch to NMC or serial (RS-232) connection | | Server wakes randomly | Broadcast WoL packets | Enable "Secure WoL" with password or directed packet only | | Dual PSU servers | Second PSU on different UPS | Connect both UPS to same output group or use single PSU for WoL | apc ups wake on lan best

"Restore on AC Power Loss"

The most reliable way to "wake" a machine behind an APC UPS is to bypass WoL entirely and use the feature in your computer’s BIOS/UEFI. Title: Optimizing Wake-on-LAN with APC UPS for Resilient
