1000BASE-X and 100BASE-FX/1000BASE-X
Each of the 1000BASE-X and 100BASE-FX/1000BASE-X uplink ports has a set of LEDs either
immediately to the right or above the port. The LE-310, LE-311, and LE-311v do not include a
PSE (pause) LED.
The following table describes the LED behavior:
The LEDs on the LE-427 are located above each port. These LEDs indicate the status of each of
the Gigabit ports.
100 Mbps Subscriber Ports (LE-327)
Twenty four pairs of LEDs are associated with the 100 Mbps ports. The LE-327 has the LEDs above
the ports in the top row and below the individual ports in the bottom row. These port LEDs
indicate the status of each of the 100 Mbps subscriber ports. For convenience, each pair of LEDs
is labeled with a corresponding port number.
