When you physically move a Powerstrip from one SX 3.1 device or port to another SX 3.1 device or port, you must delete the Powerstrip from the old SX 3.1 port and add it to the new SX 3.1 port. See Delete a Powerstrip Connected to an SX 3.1 Device and Add a Powerstrip Connected to an SX 3.1 Device.
