and plugged into a working power source?

receiving power from the external power supply.

to installation?

3. What type of cabling are you using?
Inferior cabling can result in poor performance, so it is important that you

that you know works to see if the cable is properly functioning.
5. What length HDMI cable are you using?
The cable connecting an HDMI source to the switch must be no longer
than 16 ft. (5 m) in length. The cable connecting the switch to a display
must be no longer than 16 ft. (5 m) in length.
6. Is the switch located in an area that exposes it to higher
temperatures?
