Liebert OpenComms EM is available in several models, which vary in size and number and types of ports. All models have sensor ports to monitor temperature, humidity, water detection and contact closure, and all models have either an external or built-in temperature/humidity sensor. The Liebert OpenComms EM supports a 10Mbit Ethernet connection and provides the following functionality: Web interface using HTTP, user authentication, e-mail and paging notification, SNMP support including Nform and graphing.
- Liebert OpenComms EM controller takes up zero U rack space and can support any combination of two sensors. The supported sensors are temperature, humidity, temperature and humidity combination and contact closure.
- Liebert EM PDU controller version has two sensor ports and two serial ports for connection to the Liebert Managed Power Advanced Power Strips. It takes up zero U rack space.
- Liebert vEM-14 controller is a 1U rack mountable device that uses the same sensors and has the same features as the Liebert OpenComms EM controller but with additional inputs. A built in temperature and humidity sensor allows for the monitoring of the local temperature and humidity without the use of one of the sensor ports. The vEM-14 has 4 sensor ports, 2 serial ports, 1 internal temperature & humidity sensor and 10 dry contact inputs through the use of screw terminals.
Flexibility:
- Network connectivity, allowing flexibility to receive both e-mail and paging notification. Personnel are notified when conditions exceed user-defined limits.
- Sensors for both the Liebert vEM-14 and the Liebert EM are available in both 15 and 60 foot lengths.
Higher Availability:
- Expanded monitoring capability to include water detection, ensuring against downtime by increasing the likelihood that potential problems are detected before they occur.
- Built in temperature & humidity sensor, allowing flexibility to utilize an unused sensor port for additional monitoring and further ensuring against downtime.
Lowest Total Cost Of Ownership:
- Ten dry contact inputs, increasing monitoring capability and ensuring against costly, unplanned downtime.
Ideally Suited For:
- Network closets to monitor for temperature problems
- Equipment cabinets to monitor for overheating
- Detectors to monitor sensitive or trouble spots in a data center
- Monitoring alarms of a unit for network notification
