INTRODUCING THE BASELINE SWITCH
This chapter provides an overview of the features and
capabilities of the 3Com Baseline Switch 2426 PWR
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 2426 PWR Plus is a
versatile, easy-to-use configurable Power-over-Ethernet
(PoE) 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.
