Product Overview
The Catalyst 3750 Metro switch, also referred to as the switch, is a stackable metro Ethernet switch that
can be used as customer-located equipment (CLE) to connect to enterprise customer routers or switches.
You can connect other devices to the switch, including Cisco IP phones, a Cisco Wireless Access Point,
workstations, servers, and PCs. This chapter provides a functional overview of the switch.

Features
You can deploy the switch as an aggregation switch. You can aggregate Ethernet traffic from other
network devices with 10BASE-T, 100BASE-TX, and 1000BASE small-form factor pluggable (SFP)
modules (1000BASE-T, 1000BASE-BX, 1000BASE-SX, 1000BASE-LX/LH, or 1000BASE-ZX SFP
modules). Refer to the switch software configuration guide for examples that show how you might
deploy Catalyst 3750 Metro switches in your network.
These are the switch features:
• Hardware
– 24 10/100 Ethernet ports
– 4 small form-factor pluggable (SFP) module slots. Two are standard SFP module ports, and two
are enhanced-services SFP module ports. The enhanced-services ports support multiprotocol
label switching (MPLS), hierachical quality of service (QoS), and enhanced 802.1Q tunneling.
For information about port numbering, see the “Front Panel Description” section on page 1-2 .
– 2 power supply slots that support AC or DC input
For instructions on installing power supply units, see Chapter 3, “Connecting the Power
Supply.”
• The switch supports these SFP modules:
– 100BASE-FX (only in the standard SFP module ports)
– 1000BASE-BX
– 1000BASE-LX
