Not all UPS units are created equal. If you are buying new or reconfiguring, look for these specific APC features:
If you want the single best configuration for waking a PC behind an APC UPS, do this:
Why this is the "Best": You no longer rely on the NIC staying semi-conscious during a brownout. As soon as the APC UPS's inverter switches back to line power, the motherboard sees the return of AC voltage and triggers a full boot. It is nuclear-proof.
A common failure point in remote power management occurs when an APC UPS shuts down a server(s) to preserve battery, but the subsequent return of utility power does not automatically restart the systems. Traditional BIOS "Restore on AC Power Loss" is insufficient for staggered or selective startups.
The best solution combines:

Wake-on-LAN (WoL) is a powerful way to manage power consumption and ensure your systems are ready when you need them. However, standard APC UPS units, including those with a Network Management Card (NMC), typically do not send WoL "Magic Packets" directly.
Instead of the UPS waking your PC, modern workflows rely on a combination of UPS power management and computer BIOS settings. How to Achieve "Wake" Performance with APC
To get the best results for remote power management with your APC UPS, follow these best practices:
Use the "Restore on AC Power Loss" BIOS Setting: This is the most reliable "auto-wake" method. When the UPS restores power after an outage, your computer detects the AC current and automatically boots up.
Configure APC "Return" Settings: If you have a Network Management Card (NMC), configure the Minimum Battery Capacity or Return Runtime Duration. This ensures the UPS doesn't turn your equipment back on until the battery has enough charge to handle a second immediate outage. apc ups wake on lan best
Leverage APC SmartConnect (Cloud Models): Newer Smart-UPS models with APC SmartConnect allow you to remotely reboot outlet groups from a web portal or mobile app. This is helpful if a device is hung and needs a hard power cycle.
External WoL Triggers: For true Wake-on-LAN (waking a sleeping PC without cycling power), use a secondary device on your network—like a router, TeamViewer, or a low-power server—to send the Magic Packet once power is stable. Recommended APC Models for Power Management
While they don't natively send WoL packets, these models offer the best remote power control features: NMC 'Wake on LAN' support - Schneider Electric Community
While APC UPS units do not inherently have a "Wake on LAN" (WoL) button, you can achieve automatic system recovery by combining UPS power-cycle settings with your computer's BIOS/UEFI configuration Schneider Electric Community Core Strategy for Recovery
The most reliable "best practice" isn't actually using a WoL magic packet, but rather ensuring the computer restarts automatically when the UPS restores power. Schneider Electric Community Step 1: BIOS Configuration Access your computer's BIOS/UEFI settings and set the Restore on AC/Power Loss "Power On" "Last State"
. This ensures that once the UPS turns its outlets back on, the PC boots immediately without needing a manual signal. Step 2: UPS Power Cycling Configure your APC UPS (via PowerChute Network Management Card ) to perform a "shutdown and reboot" cycle. Graceful Shutdown
: The software initiates a shutdown of the OS before the battery runs out. Return Delay Return Runtime Duration Minimum Battery Capacity (e.g., 15%) in the APC Network Management Card
settings. This prevents the UPS from turning on and off repeatedly if the main power is unstable. Schneider Electric Community Implementing True Wake on LAN (WoL)
If you specifically need to wake a sleeping PC remotely while it is still connected to a powered UPS:
: In Windows Device Manager, find your network adapter properties and check "Allow this device to wake the computer" "Only allow a magic packet to wake this computer" "Wake on Magic Packet" "Power On by PCIe" Network Side
: Use a secondary low-power device (like a Raspberry Pi) always connected to power to send the "Magic Packet" to your main server once the UPS confirms the mains are back. Recommended APC Tools NMC 'Wake on LAN' support - Schneider Electric Community 30 Jun 2021 — | Use Case | APC Model | Key
Wake on LAN (WoL) is a powerful tool for remote management, but it functions independently of your APC UPS hardware. To use them together effectively, you must configure your server's BIOS and network settings to listen for "Magic Packets" while the UPS maintains the power supply. Best APC UPS Models for Remote Environments (2026)
The following models are recommended for their reliable communication with management software, which is critical for coordinating shutdowns and remote reboots.
APC Smart-UPS SRT Series: Best for high reliability and scalability in server environments. Its online double-conversion topology provides the cleanest power for sensitive NICs.
APC Back-UPS BE850G2: Ideal for home offices and small networking gear. It includes 6 battery-backed outlets and 3 surge-only outlets for less critical devices.
APC Smart-UPS SMT Series: Provides the best balance of cost and performance for small-to-medium businesses. Features like LCD displays and intelligent battery management make it a reliable choice for server rooms.
APC Back-UPS Pro BX1600MI: Recommended for high-performance workstations and gaming setups. Its Automatic Voltage Regulation (AVR) stabilizes fluctuating voltage without draining the battery. How to Set Up Wake on LAN with Your APC UPS
Since the UPS does not natively send WoL signals, you must configure your connected devices and network to handle the process.
APC UPS and Wake-on-LAN: Best Practices for Remote Power Management
Managing server power remotely is critical for maintaining uptime, but combining an APC UPS with Wake-on-LAN (WoL) requires careful configuration. While a UPS protects against power loss, WoL allows you to restart a machine that has been gracefully shut down or placed in a low-power state. Top Best Practices for APC UPS and WoL
To ensure your hardware reliably wakes up after a power event, follow these industry-standard practices: Solved: Wake On LAN (WOL) behind a Smart-UPS
Master Remote Power: The Best APC UPS and Wake-on-LAN Strategies Why this is the "Best": You no longer
For IT professionals and home lab enthusiasts, the ultimate goal is a "lights-out" environment where systems can recover from a power failure without manual intervention. While APC UPS units excel at keeping hardware safe, many users mistakenly believe the UPS itself sends a "Wake-on-LAN" (WoL) signal to restart servers. In reality, the most reliable way to achieve this is through a combination of BIOS settings and strategic networking. Does an APC UPS Support Wake-on-LAN?
The short answer is no. Even an APC UPS equipped with a Network Management Card (NMC) typically does not send "Magic Packets" to wake up connected computers. Instead, the standard process relies on the UPS restoring AC power to the outlets, which triggers a BIOS-level response in the server. The Best Strategy: "Restore on AC Power Loss"
Instead of relying on a finicky WoL signal, the industry best practice is to configure your server's BIOS/UEFI.
Configure BIOS: Find the power management section and set "AC Back" or "After Power Loss" to "Always On" or "Last State".
Graceful Shutdown: Use PowerChute Network Shutdown to safely power down your OS during an outage.
Automatic Recovery: Once the utility power returns, the UPS will turn its outlets back on. The server will detect this incoming AC power and automatically boot up. When You Actually Need Wake-on-LAN
WoL is still vital if you want to turn on a server that was shut down manually, or if you need to wake a machine from sleep without a full power cycle. How to Set Up WoL for Your APC-Connected Server
To use WoL successfully, you must ensure the network card remains powered while the system is "off". Go to product viewer dialog for this item. APC Smart-UPS 2200VA smt2200rm2uc
