Link—Indicates when a valid link is detected by the receiver. The fiber optic Link
indicator must be illuminated at both ends of the segment for Ethernet data to
flow.
Figure 1 and Figure 2 show the indicators and ports for both the AT-MR118FT
and AT-MR128FT micro repeaters.

Setting Up Your Repeater
Here is an example procedure that results in the configuration in Chapter 4. The
sample configuration contains the following elements:
❑ An Attachment Unit Interface (AUI)/UTP hub connected to a 10BASE5
network in the main building
❑ An AT-MR118FT repeater in the main building
❑ An AT-MR128FT in the remote building
❑ An AUI/UTP hub in the remote building
