1. Introduction
The CyberPower RMCARD400 is a full-featured Gigabit network management card designed for remote management and monitoring of compatible CyberPower Uninterruptible Power Supply (UPS) systems. This internal card enables remote monitoring and control via a standard web browser, command line interface (CLI), Simple Network Management Protocol (SNMP), or a Network Management System (NMS). It integrates with PowerPanel Business Edition Client software for automatic server and workstation shutdown during power failures, safeguarding against data loss. The card also supports an optional environmental sensor (SNEV001) for monitoring ambient temperature and humidity, providing comprehensive oversight of your UPS environment.

4. Setup and Installation
The RMCARD400 is an internal management card designed for easy installation into compatible CyberPower UPS systems. Refer to your specific UPS model's user manual for the exact location and procedure for installing an internal management card.
- Prepare the UPS: Ensure the UPS is in a safe state for card installation. The RMCARD400 is hot-swappable, meaning it can often be installed without powering down the UPS. However, always consult your UPS manual for specific safety guidelines.
- Locate the Card Slot: Identify the dedicated internal management card slot on your CyberPower UPS.
- Insert the RMCARD400: Carefully slide the RMCARD400 into the designated slot until it is securely seated.
- Secure the Card: Use any provided screws or locking mechanisms to secure the card in place within the UPS.
- Connect Network Cable: Connect a standard Ethernet cable (RJ45) from your network to the Ethernet port on the RMCARD400. The card supports 10/100/1000 Mbps speeds.
- Initial Configuration: Once installed and connected to the network, the card will typically acquire an IP address via DHCP. You can then access its web interface via a browser for detailed configuration.

5. Operating Instructions
The RMCARD400 allows for comprehensive remote management and monitoring of your UPS system. After successful installation and network connection, you can begin utilizing its features:
- Accessing the Web Interface: Open a web browser and enter the IP address assigned to the RMCARD400. Log in using the default credentials (refer to the Quick Start Guide for initial login details).
- Monitoring UPS Status: The web interface provides real-time data on UPS status, battery levels, load, input/output voltage, and other critical parameters.
- Remote Control: From the web interface, you can perform various control actions such as initiating a graceful shutdown of connected equipment (in conjunction with PowerPanel Business Edition Client), performing battery self-tests, and managing UPS outlets.
- Event Notifications: Configure automated event notifications to be sent via email, SMS text, SNMP Traps, or Syslog server. This ensures you receive real-time alerts for power events or changes in UPS status.
- Environmental Monitoring (with SNEV001): If the optional SNEV001 environmental sensor is connected, you can monitor ambient temperature and humidity levels directly through the card's interface. Set custom thresholds for alerts.
- Security Settings: Configure MD5 security management, SSL/TLS for secure email delivery, and user authentication protocols like RADIUS, LDAP, LDAPS, or Windows Active Directory for enhanced security.

6. Maintenance
Regular maintenance ensures the optimal performance and longevity of your RMCARD400 and the connected UPS system.
- Firmware Updates: Periodically check the CyberPower website for available firmware updates for the RMCARD400. Firmware can be updated by users to ensure you have the latest features and security enhancements. Follow the instructions provided with the firmware update package.
- Environmental Sensor Check: If using the SNEV001 environmental sensor, regularly monitor temperature and humidity readings to ensure they remain within acceptable operating ranges for your UPS.
- Network Connectivity: Ensure stable network connectivity to the RMCARD400. Verify network cables are securely connected and network settings are correct.
- Event Log Review: Regularly review the event logs accessible through the card's web interface. This helps track UPS events and input/output status records, aiding in proactive maintenance and issue identification.
7. Troubleshooting
If you encounter issues with your RMCARD400, consider the following troubleshooting steps:
- No Network Access: Verify the Ethernet cable is properly connected to both the RMCARD400 and your network switch/router. Check network indicator lights on the card. Ensure the card has a valid IP address and that your computer is on the same network segment.
- Incorrect Readings/Alerts: Confirm that the RMCARD400 is securely installed in the UPS slot. If using an environmental sensor, ensure it is properly connected to the Universal port.
- UPS Not Responding to Commands: Check the communication settings between the RMCARD400 and the UPS. Ensure the PowerPanel Business Edition Client is correctly configured on connected devices for auto-shutdown features.
- Firmware Update Issues: Ensure a stable network connection during firmware updates. Do not power off the UPS or the card during the update process.
- Consult UPS Manual: For any UPS-specific issues, always refer to the user manual of your CyberPower UPS system.
- Resetting the Card: If necessary, a soft reset or power cycle of the UPS (if safe to do so) may resolve minor communication issues.
