let’s see if anyone looks at this - this Discord is not like forum.qnap.com
I have done many 25G QNAP systems. Just did another TS-h1290FX yesterday with the QNAP QSW-M5216-1T 25G switch, using the QNAP SFP28 cables. Latest QuTS h5.2.4 firmware on the QNAP, and 1.4.2 on the switch. No connection lights between the QNAP 25G and the switch 25G. Yet, I can use the same cables, and do a “loop” between the 2 ports on the TS-h1290FX, and it shows connected - and do a “loop” between any 2 ports on the QSW-M5216-1T and it shows connected. So much for “plug and play”. I am planning on manually reloading the Advanced Network Driver today on the TS-h1290FX. I just wanted somewhere to complain !
I appreciate the reply. I was the first person to complain about the QSW-M5216-1T not supporting FEC, and that is why 1.4.2 firmware was written. I also complained to Ubiquiti at the same time, which is why Ubiquiti now supports multiple FEC versions. But to address your reply - everything is currently set for RS-FEC. Both switch and QNAP NAS. And the QuTS 5.2.4 Advanced Network Driver is loaded as well. My customer is having internet issues, so I cannot remote into his system at this time, but it is my top priority to get this working, as I do tons of SFP28 installations with QNAP.
