Checking the Port LED on the Adapter
The AT-2911GP adapter card comes with two LED’s. One LED indicates
the link status for the copper port; the other indicates the link status for the
fiber optic port.
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” on page 35.
