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 basic switching unit. (Pull the unit a little way toward you while holding
the levers and the sides.)

CAUTION
When removing a basic switching unit, install a blank panel.
If you continue using the Switch without attaching a blank panel, the
airflow in the Switch cannot be maintained. As a result, the
temperature inside the Switch will rise, possibly resulting in a failure.
In addition, the radio waves generated by the Switch might affect
another device, or the radio waves generated by another device might
affect the Switch, resulting in a malfunction.
(2) Installing a basic switching unit
A basic switching unit can be installed while the Switch is on.
Note, however, that the procedure varies depending on whether the Switch is on or
off.
Remove the unit while referring to the following figure.
