The SFP+ ports on the QNAP QSW-M3212R may not be connecting or showing activity due to several possible reasons:

1. Incompatible Transceivers – Ensure that the SFP+ modules used are compatible with the switch. Unsupported third-party modules may not function properly.
2. Faulty or Improperly Seated Transceivers – Check if the SFP+ modules are correctly inserted into the ports.
3. Incorrect or Faulty Cables – Verify that the fiber or DAC cables are properly connected and in good condition.
4. Port Configuration Issues – Ensure that the ports are enabled and properly configured in the QNAP Switch System (QSS) interface.
5. Network Loop Prevention Features – STP (Spanning Tree Protocol) or other security settings may be blocking the connection.
6. Firmware Issues – An outdated or corrupted firmware version may cause connectivity problems. Consider updating the switch firmware.
7. Power or Hardware Issues – If multiple ports are not working, there may be a hardware issue requiring inspection or replacement.

Checking these factors in the QSS management interface should help identify and resolve the issue.
