Main Parts of the Web Interface The Web interface gives you access to all the features of the OpenComms EM device. You may use any Internet browser to access the Web interface. The browser shown below is just one example. -
Page 18: Tabs
The Web interface uses color coding to indicate the status of sensors connected to the unit, as shown in Table 6, to help you quickly identify sensors that require attention. In EM PDU and vEM-14 controllers, the same color scheme is used for MP Advanced Power Strips connected to the unit. -
Page 19: Thresholds In The Web Interface
Dry-Contact Sensor Thresholds A dry-contact sensor has only two states: Normal and Critical, as shown in Table 8. The user defines Normal as either Normally Open or Normally Closed and the OpenComms EM designates the opposite state as Critical. Table 8... -
Page 20: Mp Advanced Power Strip Thresholds
4.4.3 MP Advanced Power Strip Thresholds When using the OpenComms EM to monitor MP Advanced Power Strips, you may set thresholds that will trigger alerts for power, voltage, current and temperature sensors in each power strip. Each sensor has four thresholds: High Critical, High Warning, Low Warning and Low Critical. The Normal range is determined by these limits. -
Page 21: Sensor Names And Status
Sensor Names and Status The Web interface displays four items about sensors in all windows available through the Summary, Sensors and Power tabs, as shown in Table 10. The sensor’s Name is an optional user-defined description; the Description is created at the factory and cannot be changed. -
