1 INTRODUCING THE BASELINE SWITCH This chapter provides an overview of the features and capabilities of the 3Com® Baseline Switch 2816/2824-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 2816-SFP/2824-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 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 16 (2816-SFP) or 24 (2824-SFP) shielded RJ-45, 10/100/1000 Mbps auto-negotiating ports and four Small Form Factor Pluggable (SFP) transceiver slots 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. 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. SFP Ports The four SFP ports support fiber Gigabit Ethernet short-wave (SX) and long-wave (LX) SFP transceivers in

This chapter provides an overview of the features and
capabilities of the 3Com
®
Baseline Switch
2816/2824-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 2816-SFP/2824-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 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 16 (2816-SFP) or 24 (2824-SFP) shielded
RJ-45, 10/100/1000 Mbps auto-negotiating ports and
four Small Form Factor Pluggable (SFP) transceiver slots
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.
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.
SFP Ports
The four SFP ports support fiber Gigabit Ethernet
short-wave (SX) and long-wave (LX) SFP transceivers in
