NTRODUCING THE
This chapter provides an overview of the features and
capabilities of the 3Com Baseline Switch 2848-SFP 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 2848-SFP Plus is a versatile,
easy-to-use configurable Switch. It is ideal for users who
want the high-speed performance of 10/100/1000
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 44 shielded RJ-45, 10/100/1000 Mbps
auto-negotiating ports and 4 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 10/100/1000 Mbps Ports

Each 10/100/1000 Mbps port automatically determines
the speed and duplex mode of the connected
equipment and provides a suitable switched connection.
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.
