Installation Guide for the Model FE104 and Model FE108 Fast Ethernet Hubs
Physical Description 2-3
Table 2-1 describes each LED on the front panel of the hub.
RJ-45 100BASE-TX Ports
The front panel of the Model FE104 hub provides four RJ-45 100BASE-TX ports, and the Model
FE108 provides eight RJ-45 100BASE-TX ports. These standard RJ-45 connectors accept 2-pair
Category 5 UTP cable or 4-pair Category 5 UTP cable (100BASE-TX networks require only
2-pair wiring). The RJ-45 interface is an 8-pin connector.
An illustration of the RJ-45 connector and a table of pin assignments for the normal (MDI-X)
RJ-45 connector and the uplink (MDI) RJ-45 connector are in Appendix B, “RJ-45 Connector
Information.” Table B-1 provides the pinout information.

Utilization % Green On Four LEDs indicate whether the percentage of data utilization
on the hub or stack of hubs is 1%, 10%, 20%, or more than
30%.
Caution: 100 Mbps operation requires the use of Category 5 UTP cable with a 100 Mbps
certified connector. Refer to Appendix C, “Fast Ethernet and Cabling Guidelines,” for
more information on cabling.
