This chapter provides an overview of the features and
capabilities of the 3Com Baseline Switch 2226 Plus. It
also identifies the contents of the Switch package and
helps you get to know the physical features of the
device.
Overview of the Baseline Switch
The 3Com
®
Baseline Switch 2226 Plus is a versatile,
easy-to-use unmanaged switch. It is ideal for users who
want the high-speed performance of 10/100 switching
with the added functionality of Gigabit fiber links, but
do not need sophisticated management capabilities. The
Switch is shipped ready for use. No configuration is
necessary.
Features and Capabilities
The Switch has 24 shielded RJ-45, 10/100 Mbps
auto-negotiating ports and 2 Gigabit combo ports
(which comprised of a RJ-45 port and a Small Form
Factor Pluggable (SFP) transceiver slot) on the front
panel for easy, flexible connection to fiber-based Gigabit
media.
Autosensing of MDI/MDIX Connections
All ports on the Switch can autosense both medium
dependent interface (MDI) and medium dependent
interface crossover (MDIX) connections. This allows you
to connect network devices to each port using either a
normal straight-through TP (twisted pair) cable or a
‘crossover’ TP cable.
Any port can therefore be used to connect to another
switch port, server, or workstation without additional
configuration.
Autonegotiating 10/100 Mbps Ports
Each 10/100 Mbps port automatically determines the
speed and duplex mode of the connected equipment
and provides a suitable switched connection. The
10/100 Mbps ports can operate in either half-duplex or
full-duplex mode.
Gigabit Combo Ports (RJ-45/SFP)
The 2 Gigabit combo ports support fiber Gigabit
Ethernet short-wave (SX) and long-wave (LX) SFP
transceivers in any combination. This offers you the
flexibility of using SFP transceivers to provide
connectivity between the Switch and a 1000 Mbps core
network.
