Identifying External Components

indicators blink green whenever there is reception or transmission (i.e.
Activity

act) of data occurring at a port.

♦

FDX/Col. This LED indicator is green when a respective port is in
full duplex (FDX) mode. Otherwise, it is OFF for half duplex (HDX)
operations. It blinks yellow when collisions are occurring on the
respective port.

♦

Console. This LED indicator is green when RS-232 link is present.
