Exchanging a media module
If you replace an electrical media module with an optical media module (or vice versa), this
can lead to malfunctions. The IE switch therefore reacts as follows:

● The red fault LED "F" lights up.
● The event is shown in the log table in WBM.
Enabling a media module
To enable the replacement media module, restart the IE switch:
● The media module is active.
● The red fault LED "F" goes off.
