-
Built-in Web Server: Intuitive web-based interface for configuration, monitoring, and control accessible from anywhere
-
Automated Server Shutdown: Intelligent automated IT server shutdown functionality protects critical equipment during power events
-
Flexible Connectivity: Four Gigabit Ethernet ports, one fiber port, four RS-232/485 serial ports, USB ports, and HDMI outputs
-
Expandable Design: Four hot-swappable expansion slots support optional cards for additional I/O and communication interfaces
Intelligent Environmental Monitoring
The RDU501 provides comprehensive environmental monitoring capabilities essential for maintaining optimal data center conditions. Monitor temperature, humidity, water leaks, smoke, door contacts, and other environmental parameters in real time. The system supports multiple temperature and humidity sensors, digital input sensors including door sensors, water leak detection, smoke sensors, motion sensors, and vibration sensors. With its robust sensor integration, the RDU501 helps identify potential issues early, enabling proactive maintenance and significantly reducing the risk of downtime.
Complete Infrastructure Management
Designed as an upgrade to the Liebert RDU-A G2, the RDU501 integrates easily within a 19-inch standard rack with its compact 43.5mm height. The appliance enables users to monitor the performance of all IT assets including thermal management units, UPS systems, and generator sets. Advanced features include video surveillance integration, access control management, remote door opening, power management with energy consumption tracking, and historical data logging with graphical alarm reports.
Advanced IT Management Functions
Beyond environmental monitoring, the RDU501 delivers powerful IT management capabilities. Connect and manage up to 40 servers through IPMI v2.0 interfaces, providing full visibility and control. The out-of-band management features ensure you maintain access even during network outages. Serial console access enables direct server management, while the automated shutdown functionality protects servers during extended power events. Integration with Vertiv's Trellis Smart InfraSight platform provides consolidated monitoring across multiple RDU501 units for enterprise-wide visibility.
Reliable Fanless Design
The RDU501 utilizes natural cooling without fans, dramatically improving device reliability, reducing maintenance requirements, and enabling operation in dusty environments across a wide temperature range. This fanless design makes the unit ideal for edge deployments in remote locations such as BTS sites, network closets, and small server rooms where maintenance access may be limited.
Universal Connectivity
- Four 10/100/1000M Gigabit Ethernet ports with one 1000M fiber port
- Four independent RS-232/485 serial ports (self-adaptive)
- Four USB-A ports for keyboard, mouse, or USB modem connectivity
- Two HDMI ports for local display
- Four digital input ports for dry contact sensors
- Two relay output ports for alarm or control functions
- Four hot-swappable expansion slots for EXP8COM, EXP8DIAI, EXP8DOAO, and EXP2DI6DO cards
- Dual isolated power inputs for redundancy
