Product Overview
The Catalyst 3750 family of switches—also referred to as the switches—are stackable Ethernet switches
to which you can connect devices like Cisco IP Phones, Cisco Wireless Access Points workstations, and
other network devices such as servers, routers, and other switches. This chapter provides a functional
overview of the Catalyst 3750 switch models. These topics are included:
• Features, page 1-1
• Front Panel Description, page 1-3
• Rear Panel Description, page 1-22
• Management Options, page 1-27
Features
The switches can be deployed as backbone switches, aggregating 10BASE-T, 100BASE-TX, and
1000BASE-T Ethernet traffic from other network devices. See the switch software configuration guide
for examples that show how you might deploy the switches in your network.
Figure 1-2 through Figure 1-13 show the Catalyst 3750 switches.
