NOTE
Use the levers so that the connectors on the optional module and the
Switch can be disengaged correctly. When moving a lever, move the
right and left levers slowly and at the same time without exerting
excessive force.
Step 5
Remove the management and switching unit. (Use the levers to remove the unit
partway, and then hold the sides to remove the unit the rest of the way.)
