Symptom

Action

PWR LED is Off

Internal power supply has failed or is disconnected.

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

Power LED is Red 

Internal power supply has failed. Contact SMC 
Technical Support.

Link LED is Off

Verify that the switch and attached device is 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.
