4. Place the switch on a table or desk.
5. Use a drill and 1/4" carbide drill bit to pre-drill the four holes you
marked in step 3. Please review the following guidelines:

modes break up the concrete and clean out the hole.
 Allied Telesis recommends cleaning out the holes with a brush or
compressed air.
6. Insert the four anchors into the holes.
7. Have another person hold the switch at the selected wall location while
you secure it to the wall with the four M4x32mm provided screws.
