100BASE-TX 8-Port Hub
1. INTRODUCTION
This guide is intended for the system or network administrator
responsible for installing and monitoring a TRANSITION Networks
LAN Master™ TX-8 100BASE-TX 8-Port Hub. A working knowledge
of local area network (LAN) operations, including familiarity with
communications protocols used on interconnected LANs, is
assumed.
The LAN Master™ TX8 Hub
The LAN Master™ TX8 100BASE-TX 8-Port Hub (HB-E-TX-8) is a
Fast Ethernet repeater designed to meet IEEE 802.3u 100BASE-TX
standards.
LAN Master™ TX8 Hub Features
•
Eight RJ-45 100BASE-TX ports for Fast Ethernet connectivity
•
Port #8 provides LAN Master™ TX8-to-LAN Master™ TX8
MDI/MDI-X uplink option
•
19-inch rack mountable
•
Auto partitioning of ports with excessive collisions
•
Fully automatic preamble regeneration
•
Internal universal input power supply
FAST ETHERNET (IOOBASE-X)
CABLE SPECIFICATIONS
Due to the limited collision domain in 100BASE-X, use the shortest
cables possible to make a connection between any two devices.
Where collisions are not a consideration (full duplex), longer
cable may be possible.
Effective cable distances are determined by ambient RF noise and
by signal loss in the cable. Since fiber has low signal loss/meter
and invulnerability to RF noise, fiber is the preferred medium for
extending distances.
100BASE-FX Cable and Connector Specifications
The physical characteristics of the 100BASE-FX cable must meet or
exceed IEEE 802.3 100BASE-FX specifications.
