- LINK indicators:

(For FDH-608)

Color : Green

Label : Link

One link LED is displayed for each port on the hub. 

If a device is properly connected to one of the hub's ports, this port's link LED

shines steadily. This steady green color indicates the device is connected but idle.

Each time the device connected to the hub receives information, the light winks

off briefly to show activity on the line. Only data received by a port is shown by the
LED. Data sent out by a port is not displayed by the LEDs, as it is sent to all nodes
on the network. 

- RX indicator

(For FDH-608)

Color : Green

Label : Link

One link LED is displayed for each port on the hub. 

This indicator shows whenever the hub is receiving information. When data is

reaching the hub, this indicator flashes. 

- LK/RX indicator

(For FDH-616)

Color : Green

Label : Receive

The hub possesses one such LED on its front panel. This indicator shows

whenever the hub is receiving information. When the port is connected, this indica-
tor shines in a steady green, and when data is reaching the hub, this indicator
flashes. 

- 10/100 indicator

(For FDH-608/FDH-616)

Color : Green

Label : 100BASE-TX

The hub possesses one such LED on its front panel. This indicator shines in a

steady green when the port is transmitting data at 100BASE-TX speed.
