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.

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,
