Check connections between the switch, the power
cord, and the wall outlet.

•

Contact your dealer for assistance.

•

Contact SMC Technical Support.

•

Verify that the switch and attached device are powered
on.

•

Be sure the cable is plugged into both the switch and
corresponding device.

•

Verify that the proper cable type is used and its length
does not exceed specified limits.

•

Check the adapter on the attached device and cable
connections for possible defects. Replace the defective
adapter or cable if necessary.
