Web Interface Overview
12
4.2 Tabs
The tabs at the top right of the Web interface window provide access to all the functions of the
OpenComms EM device. Table 5 summarizes these functions and where to find more information.
4.3 Color-Coded Status
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.
These colors are used to display the sensor’s name, the current reading and the status of the sensor;
the colors are also used in line graphs to indicate alarm thresholds.
