Liebert EM User Manual

Two receptacles may be linked for simultaneous control. The receptacles may be on the same power 

strip or on two different power strips. When two receptacles are linked, the Connections column dis-

plays the link as x:y, where x is the OpenComms EM serial port number (1 or 2) and y is the number 

of the linked receptacle. In the example below, receptacles 4 and 7 on serial port 1 are linked, shown 

in the Connections column as 1:7 and 1:4.
Once linked, both receptacles will be turned on, off or rebooted at the same time when you click on the 

On, Off or Reboot button for either receptacle in the Power Data window, shown below.

To link two receptacles: 

• In the right side of the 

Power Data window, click on 

LINK in the Connections 

column for either receptacle, 

as shown in Figure 8.

• The  right  side  of the window 

displays the selected recep-

tacle—Receptacle 4 on Port 1 

in the example at right.

the Power Strip list box and 

select the serial port.

• Click on the Receptacle box 

and select the number of the 

receptacle to be linked.

• Click Apply to accept the 

changes. (Or click Reset to 

cancel.)

To break the link:

• In the right side of the Power Data window, click on the x:y entry in the Connections column for a 

receptacle—for example, click on 1:7 for Receptacle 4 in Figure 8.

• In the link window (Figure 9), click on the down arrow of the Power Strip list box and select 

None.

• Click Apply to accept the changes. (Or click Reset to cancel.)
