イーサネット・ポートの検出 - MicroScanner2

The tester can detect active and inactive Ethernet ports, as shown in Figure 1 and 2.

1. Ethernet port icon.
2. Port speed for an active 1000-megabit port. The speeds are 10, 100, or 1000 megabits per second. The example shows 1000 megabits per second. If the port supports multiple speeds, the number cycles through the speeds.
3. Cable length. Dashes are shown if the tester cannot measure the length. This can occur if the port does not produce reflections.

Length may fluctuate or be obviously too high if the port’s impedance fluctuates or varies from the cable’s impedance. When in doubt, disconnect the cable from the port to get an accurate length measurement.
