Getting Started With the Web Interface

5.4Power Window (EM PDU & vEM-14 Controllers)

The Power tab provides access to MP Advanced Power Strips connected to the OpenComms EM, including:

Turning receptacles on or off—all at once, individually or in pairs (see 5.4.1 - Control Receptacles)

Setting thresholds that will trigger alerts (see 5.4.2 - Configure Thresholds)

Viewing graphs of power strip data (see 5.4.3 - View Power Strip Graphs)

Creating display names for any power strip (see 5.4.4 - Create or Change Port Names)

5.4.1Control Receptacles

The Power Data window allows you to turn power strip receptacles on or off through the Web inter- face—all at once or individually. You may also link two receptacles so they may be turned on or off or rebooted at the same time.

To access the Power Data window, log in (see 5.1 - Open the Web Interface and Log In) and:

Click on the Power tab at the top of the Web interface, as shown below.
