APC Agent
APC Agent is a proprietary management service used primarily with APC (American Power Conversion) network devices such as UPS systems. It enables remote management, monitoring, and control of power events and environmental data, facilitating automation and resilience of critical infrastructure..
APC Agent running on TCP port 2161 facilitates remote communication between APC hardware devices—such as uninterruptible power supplies—and management consoles or software. It allows administrators to gather status information including load, temperature, voltage, battery status, alerts, and logs essential for infrastructure management.
This port often interfaces with APC management software like PowerChute Network Shutdown or APC Network Management Card firmware. The communication generally follows a proprietary protocol handled by APC software or SNMP extensions, enabling active configuration changes and automated event responses over the network.
Because it is widely deployed in datacenters and enterprise environments, APC Agent communication plays a key role in automated power management, graceful shutdown procedures, and centralized monitoring. Its continuous operation ensures resilience planning and minimized service disruption by proactively addressing power anomalies.
