3. Operating Instructions
3.1 Initial Access
Once the PDU is powered on and connected to the network, you can access its management interface:
- Web Interface: Open a web browser and enter the PDU's IP address. Log in with the default credentials (refer to the product documentation for specifics).
- SSH/Telnet: Use an SSH or Telnet client to connect to the PDU's IP address for command-line access.
- Serial: Connect a serial cable to the COM port and use a terminal emulator for direct access.
3.2 Energy Monitoring
The PDU provides detailed energy metrics through its web interface and API. The LCD display on the front panel also shows real-time data.
- Metrics: Monitor Kilowatt-hours (KWH), Watts, Volt-Amperes (VA), Amps, Volts, Hertz (Hz), and Power Factor (PF).
- Group Monitoring: Energy meters are dedicated to two groups of outlets: #1-8 and #9-16.
- HTTP(S) REST API: Utilize the API for programmatic access to inlet-level energy monitoring reports.
3.3 Configuration and Automation
The web interface allows for comprehensive configuration of network settings, user accounts, and automation features.
- Network Settings: Configure static IP addresses, DNS, and other network parameters.
- Email Alerts: Set up an SMTP server and define thresholds for power metrics (e.g., overcurrent, undervoltage) to trigger email notifications.
- Automation: Create custom actions and alerts based on various conditions, enhancing proactive management.
