Ethernet Port Hardware Failure on Two MikroTik Devices

I am experiencing a hardware port failure on two separate MikroTik devices in my network:

Device 1: RB5009UG+S+ — ether2 is no longer passing traffic. The LED indicator is active, however no data flows through the port. The connected device (CRS328-24P-4S+) does not receive a DHCP lease and does not respond to ping. Moving the same cable and device to a different port on the RB5009 works immediately without any configuration changes.

Device 2: hEX RB760iGS — ether3 has the same issue. The port LED is on, but no traffic passes through. Relocating the cable to another port restores connectivity instantly.

Both devices are running RouterOS 7.22.3. No configuration changes were made before the failure occurred.

So what?

What do you want from the users forum? Is not clear at all.
Replace the faulty peripherals with new ones and issue an RMA for the product, if it's under warranty.
Otherwise, dispose of it in hazardous waste as directed by your state's regulations.

thank you for your helpful response. I was looking for guidance on whether this is a known issue with these models or if there's a diagnostic step I might be missing before proceeding with RMA. Both devices developed the same symptom independently, which seemed unusual.

But they have the same owner...

who perhaps treated them in the same way from a hardware point of view,
perhaps by connecting some peripheral that burns the Ethernet ports of the devices
due to some defect or coincidence...

Do a netinstall on both devices, if the problem persists its time for RMA.
