Question about the compatibility of GLC-SX-MM with GLC-SX-MMD.

Hi ALL, My query to all of you is that if I connect a GLC-SX-MM at one end and GLC-SX-MMD at the other end, will the link come up. The difference between the modules is that one supports Digital Optical Monitoring and other does not.

According to Cisco Compatibility Matrix, GLC-SX-MM and GLC-SX-MMD transceivers are the 1000BASE-SX SFP transceiver modules for MMF with dual LC/PC connector. The only difference is that GLC-SX-MMD has additional function of DOM support, which may not affect the compatibility.

As long as you are using the correct patch cable (MM) and your backbone is also MM, then yes. The GLC-SX-MMD and GLC-SX-MM are compatible.

Thanks for contacting FixYa. I was reviewing some of the older un-answered questions trying to ensure your issue has been resolved.

You should be able to resolve this issure by just removing the top end. You will have to remove the tank, the pipe, disconnect the carb, any water hoses, and possibly the radiator. If there is no damage to the connecting rod you be able to thoroughly clean the crankcase withough removing the engine. If you have damage to the top rod end you will have to pull the engine and split the case to replace the connecting rod.
