NTRODUCING THE
This chapter provides an overview of the features and
capabilities of the 3Com
Plus. It also identifies the contents of the Switch pack-
age and helps you get to know the physical features
of the device.
Overview of the Baseline Switch 2226-PWR
Plus
The 3Com Baseline Switch 2226-PWR Plus is a versa-
tile, easy-to-use configurable Switch. It is ideal for
users who want the high-speed performance of
10/100 switching with the added functionality of
Gigabit links, but do not need sophisticated manage-
ment capabilities.
The Switch is shipped ready for use. No configuration
is necessary, unless you want to configure advanced
features such as VLAN support, link aggregation, and
traffic prioritization.

Features and Capabilities

The Switch has 24 shielded RJ-45, 10/100 Mbps auto-
negotiating ports and two dual purpose
10/100/1000BASE-T ports that operate in conjunction
with two Small Form Factor Pluggable (SFP) trans-
ceiver slots on the front panel for easy, flexible con-
nection to fiber-based Gigabit media.

While there are four physical Gigabit ports, only a
maximum of two can be operational at any given
time.

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
1000BASE-T ports also support automatic
10/100/1000 Mbps speed detection.
10/100 Mbps connections on these 1000BASE-T
ports can operate in either half-duplex or full-duplex
mode. 1000 Mbps connections, on the other hand,
only operate in full duplex mode.
