This is where combining an with Wake-on-LAN (WoL) becomes the ultimate remote management solution. By pairing these two technologies, you can automate the entire cycle: safe shutdown during a failure, and automatic revival once clean power returns. How APC UPS and Wake-on-LAN Work Together
Use APC NMC with Outlet Group Control and Delay Start .
In the BIOS, enable , Power On By PCI-E , or Resume by Onboard LAN .
): For a computer to listen for a WoL magic packet, its motherboard must receive continuous standby power ( ) from the power supply unit (PSU). apc ups wake on lan best
Since the UPS itself won't "wake" your PC over the network, the most reliable configuration involves the following steps:
[ Utility Power Fails ] │ ▼ [ APC Smart-UPS Signals NMC3 ] │ ▼ [ PowerChute Initiates Graceful OS Shutdown ] │ ▼ [ UPS Cuts Power / Utility Power Restored ] │ ▼ [ APC UPS Restores Power to Network Switch First ] │ ▼ [ Script Sends WoL Magic Packet to Target Servers ]
line. The network card dies completely. Even when utility power returns and the UPS turns back on, many modern motherboards will remain in a "Soft Off" (S5) state and refuse to listen to WoL packets because the standby power rail was completely severed and reinitialized. The Best APC UPS Hardware Configurations for WoL This is where combining an with Wake-on-LAN (WoL)
Several APC UPS models support the Wake on LAN feature. Here are some of the top models:
| Parameter | Best Setting | |-----------|--------------| | Shutdown OS when runtime < | 120 seconds | | UPS output after shutdown | (not Turn On) | | Restart UPS when utility returns | Yes, after 180 seconds | | Wake server via | External script sending WoL packet after UPS restarts |
Reboot your server and press the designated key (, Del , or F12 ) to enter the BIOS/UEFI. Navigate to the Power Management or Advanced tab. In the BIOS, enable , Power On By
While BIOS recovery works well for single servers, what if you have a complex network with switches, routers, NAS boxes, and virtual machines that need to power on in a specific order? This requires the standard protocol using a "Magic Packet."
What or hypervisors (Windows, Linux, VMware, etc.) are running on the machines you need to wake up?
This is the gold standard for enterprise setups. The card installs directly into a Smart-UPS slot, giving the UPS its own IP address to send shutdown commands and network alerts independently of any host OS.
To build an automated recovery system, it helps to understand how these two distinct technologies interact during a power event. The Shutdown Phase
Here's a step-by-step explanation of the process:
