Siemens SCALANCE XR524-8C Operating Instructions Manual page 49

To use MM900 media modules in a modular SCALANCE XR-500, follow the steps below:
1. Remove the dummy cover of the device slot into which you want to insert a media module
①
2. Pull the handle out of the media module
The media module cannot be installed unless the handle is pulled out.
3. Place the media module in the guide rails of the device slot
The media module is correctly installed when it locks easily into the device and the front
panel of the module is flush with the front of the device.
4. Push the handle back into the module
The media module is then locked in place.
Pulling a media module
To pull a media module, follow the same steps as when plugging, but in the reverse order:
1. Pull out the handle of the media module.
2. Pull the media module out of the device slot.
3. Close the device slot with a dummy cover if you are not plugging in another module.
Exchanging media modules - with change of medium
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 media module is disabled.
● 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.

The device meets degree of protection IP20, if all the module slots have either media
modules inserted or are closed by dummy covers. Do not start up the device with open
module slots since the ingress of objects can lead to damage.
If you operate the device with open module compartments, it is also not possible to
guarantee the maximum ambient temperature.
