APC AP9544 is a Network Management Card 3 designed for Easy UPS 1 Ph On-Line units, giving IT and facilities teams a way to monitor and control a single UPS remotely through a web browser, EcoStruxure IT software, or any SNMP-enabled management system. It is intended for buyers who need centralised visibility of power infrastructure without relying on manual, on-site checks.

- Fits Easy UPS 1 Ph On-Line units, adding network monitoring and management capability to a single-phase installation
- 10/100/1000BASE-T network interface with support for HTTPS, SSH, FTP, HTTP, SNMP, DHCP, BOOTP and TCP/IP protocols
- Radius authentication support for centralised user access control
- Compact card format: 5.2 cm width, 4.4 cm height, 8.0 cm depth, and a net weight of just 0.05 kg
- Rated for operation from -5°C to 45°C and storage from -15°C to 65°C, with humidity tolerance up to 95%
- Backed by a 24-month contractual warranty
The APC AP9544 is typically deployed in server rooms, small data centres, and network closets where a single Easy UPS 1 Ph On-Line unit needs to be brought into a centralised monitoring or building management system. It suits IT administrators who want alerts, logs and remote shutdown control integrated with tools such as EcoStruxure IT Expert, Data Center Expert, or third-party SNMP-based network management platforms. Because it supports open protocols alongside secure options like HTTPS and SSH, it also works well in mixed-vendor environments where the UPS needs to report into an existing monitoring stack rather than a dedicated APC-only system.
Installation of the APC AP9544 involves inserting the card into the SmartSlot of the compatible Easy UPS 1 Ph On-Line unit, then configuring network settings either through the supplied micro-USB cable connection or via DHCP on first boot. The package includes the Network Management Card itself, a micro-USB cable for initial setup, and an installation manual covering configuration steps. Purchase of the card includes a 12-month Secure NMC Subscription, which provides access to firmware updates during that period; a new subscription is required once it expires to continue receiving updates, and the NMC firmware must be version 2.5 or later to remain eligible.

APC Network Management Card for Easy UPS 1-Phase (AP9544) — our verdict
If you own an Easy UPS On-Line from the SRV series, the AP9544 is the accessory that turns it from a box in the corner into equipment you actually manage. It is APC’s current-generation NMC3 card, purpose-built for the 1-phase Easy UPS On-Line range rather than a generic adapter.
Slot it into the UPS, give it an IP address, and the unit appears in a browser from anywhere on your secure network. You get live load, battery and input readings, full event logs, and real-time notifications the moment something changes — instead of discovering the battery had failed only when the power actually went.
The feature that justifies the cost in a server room is network-based graceful shutdown. One card can shut down multiple servers cleanly before the battery runs out: no corrupted databases, no filesystem repair on Monday morning. SNMP support means it also drops straight into whatever monitoring system you already run.
This is not a card for a single desktop. But if your UPS is protecting anything you would notice going down — a rack, a NAS, a small server room — the AP9544 earns its price the first time it brings everything down properly instead of the power simply vanishing.
