MS510TXM SFP+ port with SFP Module No Link
Hello, 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 S...
Hi cflatt,
Ensure that the switch is up to date and try to do a loopback test on both the SFP+ slots of your switch to see if that works. You may also want to share the techsupport file so we can review why the switch does not recognize it.
Kind regards,
A direct loop-back on the SFP module, connecting the TX and RX port should show an active link LED link, too.
Thanks for the replies,
I tried out the loopback between both SFP+ ports of the switch and this does seem successful with amber lights flashing on both ports indicating a 1 gig link and data connection. Also I tried connecting the Multi-Gigabit Ethernet Smart Switches (MS510TXM) to the Smart w/ optional Cloud (GS716TP) between the SFP+ port of one and SFP port of the other and I also got an amber light indicating a successful 1 gig link between the two.
However, I still can only get a link/data from other external 1 gig fiber sources through the Smart w/ optional Cloud (GS716TP) switch or using separate fiber-ethernet media converters hooked up via ethernet to the MS510TXM and not directly through its fiber ports. All of these connections are with the same multimode fiber cable. I'll try and upload a tech support file
Thanks!
