Question about Cisco (GLC-LH-SM=) (glclhsmrf) Transceiver

GLC-LH-SM with a Catalyst 2960 switch

When I put in the transceiver module, and connect it it doesn't show any 'light' and it won't make the connection. distance is 200m+ on a MM 62,5 fiber which works perfectly with the existing 3COM switches & SFP's.

After doing a no shut on it, if it doesnt light still you may have to play around with negotiation, post if it still doesnt light.

Cisco disables the trans port as default, have you enabled it in the system?

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


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.

GLC-SX-MMD and GLC-SX-MM, are they compatible with each other?


Yes, the GLC-SX-MMD and GLC-SX-MM are compatible with each other, and the difference between the two is that the GLC-SX-MMD transceiver has additional support for Digital Optical Monitoring (DOM) capability.

Connecting a 3Com 2952 Plus switch to a Cisco 3750 switch


If you also have a standard copper cable (or a second fibre cable) connecting the two switches (for resilience perhaps?), this issue is probably being caused by something called Spanning Tree. This is implemented on switches as a 'loop avoidance' system, and can look like you have described with one end 'ip' and the other end no lights.

On the Cisco switch, get to a telnet/ssh/console session, log in and enter show spanning-tree and press enter.

have a look to see if the fibre interface has a status (sts column) of BLK. If it has, then this is called 'blocking' and will remain like that until you remove the second link to the other switch.

Hope that this has helped!

Loose fitting Cisco GLC-LH-SM


When inserting the GBIX - pull the little wire bit/guard down then insert it firmly into the 3750 and then push the wire back up. You will find it sits more snug.

And yes I have had this problem before.
