Troubleshooting

Follow the guidelines below to test and troubleshoot the installation in the event a problem occurs.

Note

Whenever the speed and/or duplex mode are changed during or after power ON, power OFF then power back ON the switch to load the new configuration.

If the PWR LED is OFF, do the following:

❑If the switch is installed on a desktop, check that the power adapter is securely connected to a power outlet. Also, check that the power adapter cable is securely connected to the back of the switch.

❑If the switch is installed in an AT-MCR12 chassis, check that the unit is fully seated in the slot.

❑Verify that the power outlet has power by connecting another device to it.

❑Try using another power adapter.

If the LNK/ACT LED for the twisted-pair port is OFF, do the following:

❑Check that the end-node connected to the port is powered ON and is operating properly.

❑Check that the twisted-pair cable is securely connected to the twisted- pair port on the switch and on the end-node.

❑Check that the end-nodes connected to the switch are operating in the same duplex mode.
