Dual Speed Switch 8 —Front

Alert LED

If the Alert LED is off, the unit is operating correctly.

After power on, the Alert LED remains lit (orange) for a short period of time while performing a self test. If it is continuously lit there may be a problem. Refer to the “Problem Solving” section.

Power LED

If the Power LED is lit (green), the power supply to the Switch is present.

Port Status and Activity LEDs

If the Port Status LED is off there is nothing connected to the port, or the connected device is turned off or there may be a problem with the connectivity (refer to the “Problem Solving” section). If the LED is green the speed of the link to the connected device is at 100 Mbps (100BASE-Tx). If the LED is yellow the speed of the link to the connected device is at 10 Mbps (10BASE-T). The LED will flash to indicate traffic is passing through that port.

Duplex LED’s

If the Duplex LED is lit (yellow), the port is in full duplex mode. If the LED is off, the port is in half duplex mode.
