MS510TXM SFP+ port with SFP Module No Link

Hi cflatt
You say "
I have a Multi-Gigabit Ethernet Smart Switches (MS510TXM) switch (firmware version 1.0.5.10) with 2 SFP+ ports and I want to connect it (using multimode fiber) to a different SFP port and SFP module. To do this I have an AGM731F transceiver module plugged in to the MS510TXM's SFP+ port which should allow the connection to auto-negotiate down to 1G and link to be established. My problem is that I never see any link on the MS510TXM side, with the link light off and the link being down on the Netgear interface. Forcing the connecting from auto-negotiate to 1G does not solve the issue. Curiously I do see link on the other side of the connection from the module I'm connected to."
Which switch model is used on the other side?
Which SFP module is used on the other side?
Does the port on the other side of the connection use auto-negotiation or forced 1G speed? Please check the port configuration from the other side to get an answer. Thanks
WilsonS ... the OP did (at least initially) talk of a NTGR GS716TP and AGM731F modules. In my understanding, the GS716TP should work straight away on a Gigabit fiber link, isn't it? Granted, the MS510TXM can be set to Auto or 1 G Full Duplex.
More tricky might be the deployment of two RJ-5G-SX in this configuration. Well possible, the fiber link will auto establish a link on 5 Gb/s - something the GS716TP certainly can't deal with, and uncertain what the MS510TXM does make out of this, considering Netgear does not offer a pure 5Gb modules. In my understanding, different from Copper Ethernet, cincluding MultiGig, there is no link speed negotiation at all - however, I'd be happy to learn more about this.
Just to compare, I'm operating a installation with GC728XP and a GC752XP and a pair of 10G SFP+ single mode modules ... and can't manage it to establish a 10G link speed.
Just wanted to follow up now that the issue was resolved. Netgear engineering did have to create a test firmware that I installed onto the MS510TXM switch. This firmware fixed the connection issues I was seeing to the devices that were previously not linking up. I can now get data and 1-gig link using any brand of 1 gig SFP that I use. As to what the exact problem was, I wasn't made aware. I'm assuming this should get worked into an official release later on. Thanks for all the help.
