Troubleshooting

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.

Table 4 describes the link status that LED’s indicate.
