facilitate monitoring and troubleshooting of the switch. After the switch is
turned on, the LED indicators should respond as follows:
All of the LED indicators will blink momentarily. This blinking of the
LED indicators represents a reset of the system.
The FDX/Col LED indicators blink from yellow to green.
The power LED indicator will remain ON.
