Installation Tips

Once the download is complete, follow these best practices for installation:

• Disable Secondary NICs: During installation, PowerChute asks you to bind to a network interface. Ensure you select the NIC that has a route to the UPS NMC. It is often helpful to disable unused NICs temporarily during setup to avoid confusion.
• Configuration: The setup wizard will ask for the IP address of your UPS NMC. Have that IP handy along with the NMC administrator credentials (default is usually apc / apc).
• Browser Access: Once installed, PowerChute runs as a service. You can access the web interface via https://<Server_IP>:6547 (the port may vary depending on configuration) to configure shutdown timers and load shedding.

What is PowerChute Network Shutdown?

PowerChute Network Shutdown is software that works in tandem with your APC UPS and a Network Management Card (NMC). When a power event occurs (such as a utility failure or voltage fluctuation), the UPS signals the PowerChute software over the network. The software then initiates a graceful shutdown of connected servers and storage devices, ensuring no data is lost and filesystems remain intact.

It supports a wide array of operating systems, including VMware ESXi, Microsoft Windows Server, Linux, and various Unix flavors.

A Warning About Security

PCNS 4.4.3 was released before major security standards like TLS 1.2 became mandatory. Running this version on a modern network exposes several vulnerabilities:

• Weak SSL ciphers (deprecated by PCI compliance).
• No role-based access control (RBAC) as modern standards define.
• Unpatched Java dependencies (if using the web interface on older builds).

Recommendation: If you must use 4.4.3, isolate it to a dedicated management VLAN with strict firewall rules. Do not expose the PCNS web interface to the internet or your corporate user network.
