SFPs on 2960-8TC

Answered Question

Does anyone have one of the new 2960 switches with a 100FX fiber SFP operational. I just got one of these, and found in the fine print that is does not support the GLC-GE-100FX, but the way it is worded, it sounds like it could possibly support the GLC-FE-100FX - but that would be doubtful. See the below text:


Table 3-1 lists the cable specifications for 1000BASE-X and 100BASE-X SFP modules available for the Catalyst 2960. Catalyst 2960 SFP ports can use both GLC-GE-100XX and GLC-FE-100XX SFP modules. However, the Catalyst 2960-8TC and Catalyst 2960G-8TC switches do not support the GLC-GE-100FX SFP module.

Hello,


Just checked it for you. GLC-FE-100FX (100BaseFX) is supported on 2960 compact switches. You can use it on the 2960-8 port model switch and you will be fine with it.The same module is also supported on 3560 compact model switches.


HTH,Please rate if it does.

The link you pointed to says this on the fifth Q+A so that is not correct and my question still stands - but thanks anyhow.

Hello,


I think I overlooked you question.Thanks for making me understanding it.I tried to look at the compatibility matrix for the 100MB SFP module sheet and the new 2960-8TC is not listed there.It has all the other 2960 modesl listed.

Randy,


It will work on your switch and let me know if you have any issues with that.

I got the new transceiver in yesterday, and it does in fact work on the new 2960-8TC.


I think it would be helpful if the documentation stated that the GLC-FE-100FX works in the new switch instead of implying that it works by saying the GLC-GE-100FX does not work.


In any case, my problems is solved. Thanks for checking into it.
