The Ethernet switch 1030 may include a first signal detector 1121, a second signal detector 1122, a third signal detector 1123 and a fourth signal detector 1124. The first signal detector 1121 may detect an electrical signal received through the first port 1111 and transmit a wake-up signal to the wake-up signal broadcaster 1130. The second signal detector 1122 may detect an electrical signal received through the second port 1112 and transmit a wake-up signal to the wake-up signal broadcaster 1130. The third signal detector 1123 may detect an electrical signal received through the third port 1113 and transmit a wake-up signal to the wake-up signal broadcaster 1130. The fourth signal detector 1124 may detect an electrical signal received through the fourth port 1114 and transmit a wake-up signal to the wake-up signal broadcaster 1130.

The wake-up signal broadcaster 1130 may broadcast the received wake-up signal to a plurality of

ports

1111, 1112, 1113, 1114, 1115, and 1116. The wake-up signal broadcaster 1130, when a signal received from an external device through the broadcast transmission/reception unit 805, the vehicle communication unit 820, or the local area communication unit 950 is received by any one of a plurality of ports, wakes up from the port You can receive up signals. The wake-up signal broadcaster 1130 may receive a wake-up signal from the first signal detector 1121. The wake-up signal broadcaster 1130 may receive a wake-up signal from the third signal detector 1123.

Meanwhile, the wake-up signal may include information on a target port that needs to form an Ethernet line. When a signal is received from the first processor 810 to the first port 1111, the first signal detector 1121 may transmit a wake-up signal to the wake-up signal broadcaster 1130. In this case, the wake-up signal may include target data designated by the second port 1112 as a target port for forming an Ethernet line. The wake-up signal broadcaster 1130 may broadcast the wake-up signal to the second port 1112. The second port 1112 may form an Ethernet line with the first port 1111 when the wake-up signal broadcaster 1130 receives the wake-up signal from the first signal detector 1121.

When a signal is received from the third processor 830 to the third port 1113, the third signal detector 1123 may transmit a wakeup signal to the wakeup signal broadcaster 1130. In this case, the wake-up signal may include target data designated by the fourth port 1114 as a target port for which an Ethernet line is required. The wakeup signal broadcaster 1130 may broadcast the wakeup signal to the fourth port 1114. The fourth port 1114 may form an Ethernet line with the third port 1113 when the wake-up signal broadcaster 1130 receives the wake-up signal from the first signal detector 1123.
