> 3 dayWorked great on my Cisco switch for 5 months, until it died. I think these things should last longer than that for 40 dollars...

> 3 dayI have two TP-Link TL-SG3428 switches (https://www.amazon.com/gp/product/B0916BP6J5/) and bought 8 of these modules to create two 28 port switches with RJ-45 Ethernet ports. Unfortunately when I plug any one of the 8 modules into port 25 of either switch, and power cycle it, the switch will not boot up. No Ethernet cable is plugged into the module. When I put the modules in the 3 other SFP ports, the processor utilization of the switch went to 80% and stayed there. Oddly, after a time, the processor drops off to normal and the switch is usable; just dont put a module into port 25 and expect the switch to boot up next time you need to restart it. I hooked up to the switch console port and even the output from the switch is corrupted when a module is in port 25. Take it out, power cycle the switch, and the console shows the proper boot, port status up/down messages and the login prompt. The product description says they are widely compatible with TP-Link products; it just isnt wide enough to include the TL-SG3428. I updated both switches with the latest firmware (2.0.3 Build 20210409 Rel.52950), and neither one will boot if one of these modules is installed in port 25. ***UPDATE*** Im updating this review from a 1 star to a 4 because of the great support I received from H!Fiber. While the issue with using the module in port 25 was not resolved, the modules do work in other ports and with other switches I have on my network. I saw no reason to return them and that the 1 star rating was a bit unjust. H!Fiber support sent me a new model of their RJ45 module and though it also didnt work properly in port 25, I give them high marks for trying. While waiting for the new model of H!Fibers module, I purchased TP-Link modules (TL-SM331T - https://www.amazon.com/gp/product/B09RMJWBSM/) and they work without any compatibility issues in the TL-SG3428 model switch. I also purchased a different model TP-Link switch (TL-SG2428P) and both models of modules from H!Fiber worked in all of the SFP ports on it. Seems the issue (in my situation) was isolated to the TP-Link TL-SG3428 switch.

> 3 dayI finially got around to getting 10Gbps installed to my Synology NAS. These work just fine in my ZyXEL switch and the NAS NIC card.
