Notes on inserting/removing pluggable transceivers 
 
Use only approved SFP+ transceivers 
If you use SFP+ transceivers that are not approved for SIMATIC NET devices or their 
target systems, Siemens cannot accept any responsibility as to whether the Ethernet 
Switch system will function according to the specifications. Siemens can also not guarantee 
the compatibility and risk-free use of these components. 
Use only approved SFP+ transceivers. 
 
Note 
Fixed slots for SFP+ transceivers 
The SFP+ transceivers are not suitable for media modules.
 
-8C has two fixed slots for SFP+ pluggable transceivers. 
-6M and SCALANCE XR552-12M have four fixed slots for SFP+ 
ers. 
It is, however, possible to operate SFP transceivers in the fixed SFP+ slots of the device. 
Note that the SFP+ slots only support SFP transceivers with a transmission rate of 1000 
Mbps.
 
 
Note 
The media module MM992
-4SFP and the SFP+ slots may only be fitted with approved SFP 
or SFP+ transceivers. The SFP media module can be fitted with up to four SFPs.
 
 
Note

You can plug and pull pluggable transceivers during operation. If you have questi
