Using the seven-port autosensing switch LEDs for
troubleshooting
The seven-port autosensing switch has two LEDs for each port on the switch. The
top row of these LEDs displays speed, link, and activity. The bottom row of LEDs
displays whether the unit is operating in full- or half-duplex mode.
Use the LED display to help you identify the type of problem with the seven-port
autosensing switch and then verify that:
• The switch is powered on.
• Each cable and port connection has the correct pin assignment and that no
connectors are loose.
• The Link/Activity LED glows for each port used.
If the Link LED is not on:
• Verify that the device connected to your switch has a properly functioning
power supply.
• Try using a different port on your switch to connect the device.
• Try using a different port on the device connected to your switch.
Table 12 describes the LEDs that monitor the seven-port switch.
