Figure 4: Standalone Configuration
Installing Cascaded Hubs
If you want to connect more than four ports, you can use the Uplink port to
connect to another hub. In compliance with IEEE 802.3u Class II repeater
specifications, two repeaters can be cascaded using a 5-meter cable in a single
collision domain.
Note
In a two-repeater configuration, a maximum of 205 meters (672 ft.) of
UTP cable is allowed (end station -to-end station).
To install cascaded hubs, do the following:
1. Connect a Category 5 UTP/STP cable to Port 1 of the first hub.
2. Set the MDI/MDI-X switch of Port 1 on the first hub to the MDI
position.
3. Connect the other end of the UTP/STP cable to Port 1 through 4 of the
second hub.
