GS724TP connection over GLX-SX-MMD SFP to CISCO 3560-X
I’m trying to connect my new GS724TP over MM fiber using a Network Hardware Resale (NHR) GLC-SX-MMD SFP module to my existing Cisco 3560-X switch… should it work?
any tips?
thanks

Welcome to the community! 🙂
It may or may not work. Be informed that NETGEAR recommends to use the compatible SFP module for the GS724TP which are the following listed below:
AGM731F 1000BASE-SX SFP Module
AGM732F 1000BASE-LX SFP Module
AGM733 1000BASE-LZ SFP ModuleAs reference, kindly check the GS724TP data sheet here.

Exact version please? there is an elderly GS724TP(v1) as well as a new GS724TPv2.

When I have it right, the 3560-X models are combined with an optional module for offering SFP+ (!) slots. Unless there is a similar 1G fiber module in place, I would expect this can be workable. if the SFP module is really a SFP+ 10G, it won't be able to sync because there is no speed negotiation on fiber links.
The GS724TP is brand new, purchased in the last 30 days. Don’t have a version number but the serial is 50XG215UA0456
The Cisco 3560-X I have has SFP (not SFP+) modules in. I have enough NHR GLC-SX-MMD modules to ensure they are identical at each end of the fiber link.
Thoughts?
Afraid, have no reference to the serial numbers. A GS724TP with an early 3.x and current 5.2.x would be a v1 model, one with a v1.x and current v2.0.x firmware would be a v2 model. 8-)
Let's assume it's a decent model.
Does a loopback fiber (one fiber from tx to rx) enable the module, indicating a fiber link? Test both ends of course.
For another test, plug two SFP modules in a switch, and connect these in a loop-back. this should bring up the fiber link up. Needless to say, the fibers need to be crossed.
Not sure if the cli commands are implemented - try eg ;# show fiber-ports optics all
Can't see why the link should not be established end-to-end.
