CAUTION
Remember the orientation of media modules.
On modular devices, there are always two module slots arranged opposite each other.
Remember the correct orientation when installing MM900 media modules.
Example:
● The first MM900 media module is installed in slot 1.
● The second MM900 media module installed in slot 2 must be turned through 180 degrees.
On modular devices for rack mounting, pairs of module slots are located one above the other
in which modules can be inserted in a specific order:
Example of a rack device:
● The first MM900 media module is installed in slot 1.
● The second MM900 media module installed in slot 7 must be turned through 180 degrees.
Other modules are then inserted in slots 2 and 8 or 3 and 9 etc.
The permitted operating temperature is decided by the fully equipped device ( media
pluggable transceiver).
With modular devices, it is not only the switch that decides the permitted operating
temperature of the overall device but also the temperature ranges of the MM900 media
modules and the SFP transceivers. You will find details in the technical specifications of the
relevant components.
The following aspects can restrict the maximum permitted operating temperature:
● The orientation of the carrier device.
● The use of SFP transceivers.
● The use of transceivers of the types LH, LH+ or ELH.
NOTICE
Use only approved pluggable transceivers
If you use components not approved by Siemens AG, in particular SFP / SFP+ transceivers,
Siemens cannot accept any responsibility for the correct functioning of the "Ethernet switch
system" according to the specification.
If components are used that have not been Siemens approved, Siemens cannot vouch for
their compatibility or for risk-free use of these components.
Note
Use media modules only in an approved modular device
Use an MM900 media module only for a device equipped with suitable slots for such modules.
Example: X308-2M.
The names and labeling of the media modules differ
● Example: The device is called, for example, "MM992-2SFP" [6GK5 992-2AS00-8AA0], the
labeling on the device is "9922AS". You will find detailed information on the labeling of the
media modules in the "MM900 media modules" compact operating instructions.
