Alternatively, the number of the LED lamps 51 is set to 5.

The first test interface 1 and the second test interface 2 are RJ45 interfaces. RJ45 interfaces are a common type of network connection interface used to connect computer network devices, such as computers, routers, switches, etc. Such interfaces are commonly used in ethernet networks to transmit data and power. The RJ45 interface typically employs an 8P8C jack with 8 metal contacts for plugging in the connection of the network cable. Such interfaces typically use twisted pair or network wires (e.g., cat5e, cat6, etc.) to connect the devices and network together through a plug.
