Liebert® RDU-A Intelligent Monitoring Solution The Liebert® RDU-A intelligent monitoring hardware is an intelligent monitoring platform from Emerson Network Power that allows data center administrators to combine monitoring of the equipments, environment and safety of the facility altogether. Its ¼exible structural design enables the user to customize con»gurations according to the speci»c requirements of the IT infrastructure operations. The Liebert® RDU-A allows data center managers to perform the following operations through a secure web page: FRONT Monitoring of the health and status of the equipment Environment temperature and humidity Transmission of control or commands to the equipment and parameter setting Data and logs of historical information of alarms and noti»cations BACK 3rd Party Communications: The Liebert® RDU-A serves as the communication gateway for the equipment and the Liebert® RDU-M solution. It intelligently collects and communicates data and commands, giving IT administrators a comprehensive view of what’s happening at the equipment level of the facility.

Modbus 485 Communications Maximum of 16 devices in an RDU module Each COM port can support 4 daisy chain 485 Daisy Chain connection (need to be same device) 2. SNMP Communication Maximum of 8 SNMP devices can be attached to High Level Modbus 485 Communications 1 RDU module Note: • Maximum of only 16 devices can be attached to 1 RDU module. This can consist of all Modbus 485 communication or a combination of 8 SNMP and 8 Modbus 485 High Level Modbus 485 Communications SNMP Communications Network Switch Network Cable Network Cable • If communication to 3rd party device, will need to get SNMP MIB File for SNMP comms and Modbus Reference Library for Modbus Comms to build driver. This will incur additional charges. RDU-A Module Environmental: 1. Temperature and Temperature & Humidity Sensor Maximum of 28 sensors in 1 RDU-A (If 28 T/H Sensors are already used in 1 RDU-A, you cannot add any other type of sensor because it reached it’s limit. Standard RJ45 Straight through patch cable 2. Smoke Sensor (1x) Can use 4DI Extension sensor 3. Water Leak Sensor (1x) Can use 4DI Extension sensor 4DI Modular Extension Temperature/ Humidity Sensor Temperature Sensor 4. Door Sensor (2x) 5. Infrared Sensor Can use 4DI Extension sensor Note: Each RDU-A supports up to 28 knots (28 different sensors) Smoke Infrared Leak Door While every precaution has been taken to ensure accuracy and completeness herein, Emerson Network Power assumes no responsibility, and disclaims all liability, for damages resulting from use of this information or for any errors or omissions.
