## Long description

The Legrand CS102 Internal Ethernet 1000 Mbit/s Wired Connectivity is an internal network interface module designed for UPS management. It installs into a dedicated slot in compatible UPS units and provides real-time control and event management (power failure, overload, bypass, fault, etc.) without requiring external software. The device supports 9–30 VDC power supply (external versions include the power supply) and is available in professional and industrial variants with additional RS232/RS485 communication ports.
Advantages
The CS102 offers a multi-language web user interface and graphical monitoring via standard web browsers, SNMP or MODBUS network management systems, and UNMS/UNMS II software. It logs measurements, alarms, and battery tests with timestamps in non-volatile storage and supports NTP time synchronization. Firmware is updatable. An integrated scheduler can program UPS on/off cycles and battery tests, and the adapter can send event notifications by email or SNMP TRAP. The module supports multi-server shutdown through the CS102 Shutdown Client (Windows Vista and later, and Linux) and Wake on LAN for remote start.
Suitable for
Internal installation in compatible UPS units for centralized management
Monitoring and remote management of UPS in small and medium business environments
Industrial or professional setups requiring RS232/RS485 connectivity (professional/industrial versions)
Environments needing scheduled battery tests and event notification via email or SNMP

How to use
Insert the CS102 internal module into the dedicated slot of a compatible Legrand UPS and connect it to the local wired network at up to 1000 Mbit/s. Access the web interface through a browser or integrate the device with SNMP/MODBUS network management systems or UNMS/UNMS II for configuration and monitoring. Configure NTP for accurate timestamps, set up event notification (email or SNMP TRAP), and schedule automatic battery tests or UPS on/off actions via the built-in scheduler. Install the CS102 Shutdown Client on servers and workstations connected to the UPS to enable controlled shutdown procedures.
Usage recommendations
Use the internal CS102 module in UPS units that explicitly support the Legrand CS102 form factor and ensure firmware is kept up to date. For centralized monitoring, configure SNMP or UNMS integration and enable NTP to maintain accurate logs. When deploying in production environments, install the Shutdown Client on all protected machines and test scheduled battery tests and shutdown procedures during maintenance windows.
