Introduction
Congratulations on your purchase of the NETGEAR™ Model FE104 4-port Fast Ethernet Hub or
the NETGEAR Model FE108 8-port Fast Ethernet Hub. Both hubs are IEEE 802.3u-based Class II
repeaters that provide you with a low-cost, high-performance network solution and are designed to
support power workgroups operating at 100 Mbps.
Users who are operating network-intensive applications on powerful workstations require more
bandwidth than the conventional 10BASE-T network. By migrating these users to a 100 Mbps
network, you can increase the bandwidth and improve response times. By installing the Model
FE104 or Model FE108 hub in your network, you can create a power workgroup with many users
who can share access to centralized network devices (such as servers and printers) at 100 Mbps.
This guide describes how to install and use the hubs. It includes physical configuration guidelines
for connecting multiple hubs, connecting Fast Ethernet stations, and making network connections.
This guide is intended for individuals who have the following background and experience:
• Working knowledge of basic Ethernet
• Familiarity with the differences between the 10BASE-T and 100BASE-T specifications
Introduction 1-1
Installation Guide for the Model FE104 and Model FE108 Fast Ethernet Hubs
Features
The Model FE104 and Model FE108 hubs have the following key features:
• IEEE 802.3u standard compliance allows interoperation with all 100BASE-TX Fast Ethernet
(100 Mbps) products.
• Class II compliance enables network expansion by daisy-chaining two hubs together.
• Easy Plug and Play installation with no software to configure saves time and minimizes the
potential for configuration errors.
• Each hub is equipped with:
— 4 or 8 100BASE-TX ports to provide fast information exchange, resource sharing, and
client or peer-to-peer communication using simple Category 5 unshielded twisted pair
(UTP) wiring.
— RJ-45 ports with built-in LEDs to clearly indicate the status of each port.
— Additional LEDs to provide network traffic status for the hub.
— Normal/Uplink push button to simplify network extension. In the uplink mode, two hubs
can be daisy-chained using simple, straight-through UTP cables.
• Compact, sturdy metal case design enables easy tabletop or under-desk installation.

Physical Description
This chapter is divided into sections on the front and rear panel components of the Model FE104
and Model FE108 hubs. Use the key at the bottom of each illustration to identify the associated
component.
Front Panel
The front panel contains the LEDs, RJ-45 100BASE-TX port connectors, and Normal/Uplink push
button. Figure 2-1 shows the front panel of the Model FE104 hub, and Figure 2-2 shows the front
panel of the Model FE108 hub.

LED Display
Three LEDs on the front panel of the hub and two on each port connector allow you to identify the
following information:
• Status of the hub power supply
• Collision occurrence on an Ethernet segment in a standalone hub or a stack of hubs
• Data utilization percentage of the Ethernet segment in a standalone hub or a stack of hubs
• Link and receive activity for all ports in the hub
• Partition status for all ports in the hub
