Link LED: This LED, located to the right of the 10Base-T connector, will
turn green when the Access Point has a physical connection to the Ethernet
network. However, this LED reflects Ethernet activity as well as link integ-
rity. Therefore, when an Ethernet cable is attached and there is Ethernet
activity, the LED will blink off momentarily. When a damaged or improper
Ethernet cable is attached and the unit attempts to send data through its
Ethernet port, the LED will blink on momentarily.
The two yellow LEDs are nonfunctional and reserved for future use.
