Setting the Uplink Switch
The uplink switch lets you convert the repeater's 8th RJ-45 port to an
uplinkable port so that you can interconnect two repeaters without the need for
special crossover cables. The default setting for the switch is MDI-X (Media
Dependent Interface-Reversed that is, standard repeater port). To convert Port
8 to an uplinkable port, use a small, slotted screwdriver, or a similar tool, to
set the switch to the MDI position.

Interconnecting Repeaters
You can interconnect two repeaters, providing up to 14 ports in the same
collision domain (Segment).
To interconnect two repeaters, set the uplink switch as described in “Setting
the Uplink Switch” in the previous section and connect the repeaters as shown
in Figure 3-5.
NOTE: The maximum recommended cable distance between two repeaters is 25
meters (82 feet). Exceeding this limit provides unreliable results.
