3-4 Installing the Repeater
The default setting for the uplink switches is
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
(Default)
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
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.
