You can visually delete a powerstrip connected to an SX 3.1 device even if the powerstrip is still physically connected. If you physically disconnect the powerstrip from the SX 3.1 device with which it is associated, the powerstrip still appears in the Devices tab beneath that device. To remove it from display, you must delete the powerstrip.
To delete a powerstrip connected to an SX 3.1 device:
In the Devices tab, select the powerstrip you want to delete.
Choose Devices > Device Manager, Delete Device.
Click OK to delete the powerstrip. A message appears when the powerstrip has been deleted. The powerstrip icon is removed from the Devices tab.
