CHAPTER 2: Introduction
2.1 General Overview
The 9-Port Personal MiniHub is a workplace hub in a very compact
package. It is simple to install and use in an office or lab environment,
requiring no special rack cabinets or wiring-closet apparatus. It is a
standard physical-layer Ethernet product and operates independently of all
software.
Personal MiniHubs provide a simple and inexpensive solution for
networking a personal multi-system office using 10BASE-T twisted-pair
cabling. They can expand an existing single-network-port outlet to provide
up to eight extra ports in the immediate office or lab area.
Personal MiniHubs are also well suited for small-to-medium-size office or
lab environments (two to eight users) that need an independent Ethernet
network. They operate as self-sufficient units to provide 10BASE-T
Ethernet connectivity for local users and devices. Small independent
networks built using the 9-Port Personal MiniHubs are easily expanded by
taking advantage of the MiniHubs’ uplink-switchable port to add hubs of
equal or greater capacity in a cascade (see
Section 3.3
).
The small size of the Personal MiniHubs make them very useful for
demonstration situations in conference rooms and in exhibitions where a
temporary or expansion network is needed. The MiniHubs are also handy
as a piece of test equipment that can be easily inserted into the network to
provide a test port, and then removed after the testing is done. They take
up minimal space and use minimal power, and are rugged enough to be
carried in a coat pocket for possible emergencies.
Personal MiniHubs fit easily into the workplace environment. They can
be table-top- or shelf-mounted, or you can use the included Velcro
®
strip to
mount MiniHubs on walls or on the back or side of a desk or cabinet. All of
the wiring connectors are in the same plane so that wiring space is neat and
minimal. The external power supply conveniently plugs into an available
AC wall receptacle or power strip.
The 9-Port Personal MiniHub’s RJ-45 ports support connection of up to
nine workstations or other network devices over full-length 10BASE-T cable
segments. Personal MiniHubs fully comply with the IEEE 802.3
