Checking the Port LED on the Adapter

The AT-2701 series adapter comes with one or two LED’s, depending on the model. You can use the status of the port LED for troubleshooting.

The AT-2701FXa model comes with a single combination LED that indicates both the link status and activity status.

The AT-2701FTXa model comes with two LED’s. One LED indicates the link status for either the copper or fiber port; the other indicates the activity status for the port with the valid link.

Note

Before the port LED can provide troubleshooting information, the driver software for your particular operating system must be installed and the adapter must be connected to the network. See Chapter 3, “Installing the Driver Software for Windows” on page 33.
