5. Adding and Replacing Optional Modules
154
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 network interface unit. (Pull the unit a little way toward you while
holding the levers and supporting the sides.)

The components in a network interface unit might be very hot. Do not
touch any components with your hands. Doing so could result in
burns.
CAUTION
When removing a network interface 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 network interface unit
A network interface unit can be installed while the Switch is on.
Note, however, that the procedure varies depending on whether the Switch is on or
off.
Install the unit while referring to the following figure.
