Am referring here to the Gigabit Switch in metal design. Immediately after the power supply, the appliance after what feels like 5 seconds to operate and works flawlessly. It is also very good to recognize whether a Fast Ethernet (100 Mbps) or Gigabit Ethernet concern (1000 Mbit) and indicated via LEDs. Respect. the throughput rates I have seen no measurable delay when comparing direct connection to Fritzbox or via switch. Configuration is not necessary to machine work right away - perfect!
