Section 1 - Introduction

The MaxTech FHX-8100 is an 8-port hub compliant with the IEEE 802.3u
100Base-TX fast ethernet standard. The eight RJ-45 ports connect workstations
or other devices together on a 100Base-TX fast ethernet network using twisted-
pair cable. An additional crossover port connects this hub to a second hub using
a standard (straight-through) network cable for easy network expansion. A full set
of LED indicators assist in network troubleshooting.

The package contains the following items:

• Hub
• Power cord
• User’s Guide

Section 2 - Installation

1.

Locating the Hub - Place the hub in a location central to your networked
computers, or within the maximum cable length (328 ft.) to the farthest
computer.

2.

Connecting the Power cord - Insert the power cord into the hub’s power
connector (See Figure 1). Plug the other end of the power cord into an AC
power outlet. The hub is powered on when this connection is made. The
power switch has been eliminated to reduce the chance that the hub will be
accidentally turned off.

3.

Connecting Workstations - Connect one end of a Catagory 5 twisted-pair
cable into an open port (1 through 8, except the Daisy-Chain port) on the hub
(See Figure 1). Connect the other end of the cable to the computer to be
networked. The length of the cable must be less than 328 feet (100 meters).

2.1

Connecting Hub to Hub

The network can be expanded beyond eight workstations by daisy-chaining two or
more hubs together. The hub’s eighth port features an additional cross-over con-
nection to facilitate daisy-chaining hubs using standard cable. Plug one end of a
standard straight-through cable into the Daisy-Chain port and the other end into a
regular port (1 through 8) of a second hub. Refer to Appendix A for more informa-
tion on daisy-chaining hubs.

Note: The Daisy-Chain port is port number 8 with a reversed pin-out. The daisy-
chain port and port 8 cannot be used simultaneously.
