In an age where downtime can cost thousands per minute, having eyes on your uninterruptible power supply (UPS) from anywhere is no longer optional—it’s a necessity. The APC UPS Network Management Card 3 (AP9640), from Schneider Electric’s renowned APC brand, fits seamlessly into compatible Smart-UPS models via the SmartSlot interface. This compact card transforms your UPS into a network-connected powerhouse, enabling secure remote monitoring, control, and automated shutdowns through PowerChute Network Shutdown software. As of October 2025, the AP9640 remains a cornerstone for IT infrastructure, offering Gigabit Ethernet speeds and enhanced security to safeguard data centers, servers, and critical applications. In this blog, we’ll unpack its capabilities, specs, real-world performance, and why it’s a smart upgrade for proactive power management.
Why the AP9640 is Essential for Modern IT
Power outages don’t announce themselves, but they can wreak havoc on unprotected systems. The AP9640 bridges this gap by providing mission-critical visibility into UPS status, environmental conditions, and power events— all from a web browser, command line, or SNMP tools. It integrates with EcoStruxure IT for centralized oversight and supports protocols like BACnet/IP and Modbus TCP for building management systems. With a 1-year Secure NMC Subscription included for firmware updates, it ensures your setup stays current against evolving threats. Ideal for hybrid workforces, this card minimizes on-site visits, reduces risks, and supports graceful shutdowns in physical, virtual, and hyper-converged environments.
Key Features That Drive Uptime
The AP9640 packs enterprise-grade smarts into a plug-and-play form factor:
- Remote Monitoring and Control: Real-time access to UPS metrics like battery health, load levels, and runtime estimates via intuitive web interfaces or CLI.
- PowerChute Network Shutdown: Automates safe server shutdowns during extended outages, protecting data across Windows, Linux, VMware, and Nutanix setups.
- Advanced Security: 2048-bit SSL/TLS encryption, multi-factor authentication, role-based access, and compliance with Radius and LDAP for fortified defenses.
- High-Speed Networking: Gigabit Ethernet (10/100/1000BASE-T) with IPv6 support for seamless integration into modern, high-bandwidth networks.
- Expanded Logging: 100x more data and event storage than predecessors, with multi-language support for global teams.
- Integration Versatility: Works with SNMP traps, email/SMS alerts, and third-party platforms for comprehensive event management.
- Energy Efficiency: Green Premium certified, promoting sustainable operations with optimized power use.
These features make it a step up from older cards like the AP9630, delivering faster performance and broader compatibility.

Installation and Performance: Plug-and-Play Power
Setup is straightforward: Slide the card into your UPS’s SmartSlot, connect the RJ-45 cable, and access the default IP (typically 192.168.1.254) via a web browser for configuration. PowerChute software installs on servers for automated responses, with wizards guiding static IP setup and threshold tuning. Performance-wise, users report lightning-fast response times for alerts and reboots, even in multi-user scenarios. In 2025 tests, it handled simulated outages flawlessly, logging events with granular detail. The high-speed processor ensures smooth operation under load, though initial firmware flashing might take 10-15 minutes. Note: It’s compatible with a wide range of APC models, including SMT, SRT, and SURT series, but verify your UPS’s SmartSlot version.
Pros, Cons, and User Insights
