The CyberPower RMCARD205 is a network card as optional accessory for remote monitoring and control of Uninterruptible Power Supplies (UPS) from the CyberPower series. It is inserted into the SNMP/HTTP network slot of the UPS and enables remote management via a local network or the internet. The card serves for monitoring the UPS status, scheduling shutdowns, starts, and reboots, as well as for notifications in case of power failures. Communication takes place via wired Ethernet connections, with the card providing two RJ-45 connectors – one for the network and one for an optional environmental sensor. The maximum data transfer rate is 100 Mbit/s, with cabling technology supporting 10/100. The card is designed for use in server rooms, back offices, or data centers where centralized device management is required.

Applications

The RMCARD205 is specifically intended for UPS systems from the CyberPower series OL, OLS, OR, and PR. It enables integration of the UPS into existing Network Management Systems (NMS) and provides administrators with the ability to monitor UPS operation via a web browser, command line interface (SSH, Telnet), or dedicated PowerPanel management software. The card is particularly suitable for environments where continuous power supply is critical, such as IT infrastructures, server rooms, or critical applications that must be protected against data loss.

Functions and Features in Detail

The card supports a wide range of network protocols, including IPv4/v6, SNMPv1/v3, HTTP/HTTPs, TCP/IP, UDP, DHCP, NTP, DNS, SMTP, SMTPS, SSH, SSL, TLS, Telnet, FTP, SCP, Syslog, and Modbus TCP. These protocols enable flexible integration into existing networks and the use of various monitoring and control methods. Event logging documents the operational history of the UPS, ensuring a traceable record of system activities. In case of power issues, administrators are automatically notified via email, SNMP traps, or SMS. The hot-swap function allows for easy insertion or replacement of the card without interrupting UPS operation.

Technology Explained Simply

The RMCARD205 operates as a plug-and-play component, directly inserted into the expansion port of compatible UPS units. Network connection is via Ethernet, with the card providing two RJ-45 connectors. One is for network communication, the other is for connecting an optional environmental sensor, which can monitor temperature, humidity, or other environmental parameters. The card features LED indicators for status display (Tx/Rx, Link). Firmware can be updated by the user, enabling adaptation to new requirements or security standards. The user interface is multilingual and supports, among others, Chinese (traditional and simplified), English, French, German, and Spanish.

Compatibility and Accessories

The card is compatible with the CyberPower UPS series OL, OLS, OR, and PR. An optional environmental sensor can be connected to the second RJ-45 port to capture additional environmental data. The card supports the use of PowerPanel Business (for small to medium applications) and PowerPanel Enterprise (for large systems) for centralized management. Authentication is performed using secure methods such as RADIUS, LDAP, LDAPS, and Windows AD.

Installation and Mounting

Installation is performed by simply inserting the card into the designated expansion port of the UPS. The plug-and-play function enables quick commissioning without additional configuration. The card is designed for operation in a temperature range of 0 to 40 °C and relative humidity of 0 to 90 %. Storage is possible in the range of -10 to 50 °C and humidity of 0 to 95 %. The maximum operating altitude is 3000 m, and the storage altitude is 15000 m. Physical dimensions are 54 mm (width) × 36.1 mm (height) × 76.5 mm (depth), and the weight is 38 g. The card is blue and complies with CE, FCC Class A, and RoHS conformity certifications.

Operational Advantages

The RMCARD205 enables centralized, web-based device management, increasing the efficiency of IT infrastructure. Automatic notifications during power failures and the ability to shut down servers and workstations automatically via software reduce the risk of data loss. The multilingual user interface and Syslog support facilitate integration into international or heterogeneous networks. The hot-swap function and plug-and-play installation reduce downtime during maintenance. The card is designed for use in critical IT environments where reliable power supply and continuous monitoring are required.
