Liebert EM User Manual

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)

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. 

• Select a port from the left side of the window by clicking on the name of the port. The right side of 

the window shows the selected power strip, its status and current readings.

• Two buttons below the readings allow you to control all receptacles at once:

• Click  the  All On button to turn on all receptacles in the power strip. 
• Click  the  All Off button to turn all receptacles off. 

• The receptacle controls at the bottom of the window allow you to turn individual receptacles on or 

off, reboot them and link the controls of two receptacles.

• Click  the  On button to turn a receptacle on. 
• Click  the  Off button to turn it off. 
• Click Reboot to turn a receptacle off for ten seconds and then back on—the receptacle must 

be on before you can reboot.
