Technical Details

what runs on :6547

In typical PowerChute Network Shutdown deployments, TCP/6547 serves an HTTPS interface, so a client normally begins with a TLS handshake rather than a cleartext application exchange. The port is associated with APC’s UPS shutdown-management software; exact behavior and configuration can vary by product version. Although the IANA assignment lists both TCP and UDP, the usual PowerChute use is TCP, and the assignment alone does not establish that a UDP listener is present.

security overview

This service can expose UPS and shutdown-management controls, so restrict access to trusted management networks and require authentication. HTTPS encrypts normal traffic, but encryption does not make an exposed management interface safe; keep the software updated and avoid publishing it directly to the internet.
