Network Troubleshooting
Introduction
This document is meant to help you understand some of the problems that may
arise with the implementation of our equipment. We will do our best to help
you resolve problems related to our equipment, but please understand that Adtec
is not in the business of supporting your network. It is advisable to consult your
Network Administrator before installing any Network related products.
The First Question to ask yourself when faced with a Network problem:
Is my
Problem a Hardware or Configuration Problem?
Sources of Hardware Related Problems
Cables are the most common Hardware Problem encountered. We recommend
that you use 10BaseT (unshielded, twisted pair, and 4 Conductor Min (Cat 3))
cables. We use Straight cables for PC – Hub and Soloist – Hub connection. The
Swapped (crossover) cables are used for Hub – Hub, PC – PC, and Soloist -
Soloist connection. NOTE: Some Hubs have a Crossover switch which will
allow the use of either a straight through or swapped cable.

Caution:
Another problem related
to Cabling is the Connectors. The
RJ-45 Connectors required for
CAT-3 or CAT-5 cables need to be
tightly crimped. It is suggested that
only premade cable be used. Any
gaps in the crimp will cause
connection problems.
