I understand that you are concerned about the lack of grounded Ethernet ports on your Deco BE63 units, especially given your use of shielded CAT 8 cabling with metal couplers and a PoE-based ISP setup. According to our knowledge base, the Deco BE63 (and its hardware-identical models BE65 and BE11000) feature 4 x 2.5Gbps Ethernet ports, but these ports are not specifically described as grounded or designed for shielded cable grounding. This is a common design choice for consumer mesh networking products, which are primarily intended for indoor residential use where electrical grounding of Ethernet ports is not typically required for reliable data transmission or device safety. While your TP-Link 2.5Gbps router may have grounded metal ports, Deco mesh units prioritize ease of deployment and compatibility with standard home wiring. As long as you are not experiencing data corruption or connectivity issues, the absence of grounded ports should not affect performance in typical home environments. If your installation involves industrial-grade cabling or environments with high electromagnetic interference, additional grounding measures may be considered, but these are outside the standard design scope of Deco mesh products.
