A: Check the LED indicators on the switch. Typically, power LEDs should be solid, and link/activity LEDs should show connectivity status for each port.
Q6: What cable length limitations apply to 2-port switches?
A: Standard ethernet cables should not exceed 100 meters (328 feet) between the switch and connected devices for optimal performance.
Q7: Are 2-port switches suitable for gaming applications?
A: Yes, 2-port switches can improve gaming performance by providing dedicated ethernet connections, reducing latency compared to WiFi connections.
Q8: How much power do 2-port switches consume?
A: Basic unmanaged 2-port switches typically consume 2-5 watts, while PoE-enabled versions may consume 15-60 watts depending on connected device power requirements.
