The default setting for the uplink switches is MDI-X (Media Dependent
Interface-Reversed, that is, a standard IN repeater port).
To convert Port 1 or Port 12 to an uplinkable OUT port, use a small, slotted
screwdriver, or a similar tool, to set the switch to the MDI position (Figure 3-
4).
NOTE: IEEE specifications allow only one 100 Mb/s uplink connection per collision
domain. Therefore, you cannot uplink to two 100 Mb/s repeaters. However, you
can use both uplink ports for 10 Mb/s uplink connections.

Interconnecting Repeaters
You can interconnect two repeaters, providing up to 48 ports in the same
collision domain (segment). You can also connect the repeater to a single-
speed repeater (10 Mb/s or 100 Mb/s).
To connect the repeater to another repeater, set the appropriate uplink switch
as described in “Setting the Uplink Switches” in this chapter and connect the
repeaters as shown in Figure 3-5.
NOTE: At 100 Mb/s, the maximum cable distance between two repeaters is 5
meters (16.4 feet) while still allowing a maximum distance of 100 meters (328
feet) for repeater to workstation/server connections. At 10 Mb/s, the distance
between two repeaters can be up to 100 meters.
