INTRODUCTION
This chapter describes features of the 3Com CoreBuilder
™
5000
Ethernet 24-Port 10BASE-T Module (Model Number 6124M-TPL6). For
more information on the 3Com
®
CoreBuilder 5000 hub, refer to the
CoreBuilder 5000 Integrated System Hub Installation and Operation
Guide.
The CoreBuilder
5000 Ethernet
24-Port 10BASE-T
Module
The CoreBuilder 5000 Ethernet 24-Port Module is an IEEE 802.3
repeater module that complies with the 10BASE-T standard. It connects
up to 24 devices (PCs, terminals, printers, modems, etc.) to the
CoreBuilder 5000 hub. Two 50-pin Telco-type connectors connect to
24 10BASE-T-compliant ports using 25-pair 10BASE-T cables or 12-leg
"hydra" cables.
The 24-Port module provides the following features and benefits:
■ Provides per-port switching on all eight of the backplane segments
and all eight of the isolated segments (supports up to six segments
simultaneously).
■ Offers high port density at a low cost per port.
■ Supports up to 100 meters on 10BASE-T-compliant unshielded
twisted pair (UTP) wiring.
■ Features hot swap capability so that you can install or remove the
module without having to power down the hub.
■ Supports scalable network management architecture which includes
one Network Monitor Card (NMC) per 24-Port module.
■ Supports the CoreBuilder 5000 Ethernet security card for private
Ethernet conversations.
■ Provides system-configured autopartition threshold, for flexibility in
dealing with collision-related network slowdowns.
