Data Sheet
The Cisco Catalyst 3750 Series is available with either the IP Base image or the IP Services
image. The IP Base image feature set includes advanced quality of service (QoS), rate-limiting,
access control lists (ACLs), and basic static and Routing Information Protocol (RIP) routing
capability. The IP Services image provides a richer set of enterprise-class features, including
advanced hardware-based IP unicast and multicast routing.
An additional Advanced IP Services license is also available. This license is required for IPv6
routing (Layer 3 switching).
Cisco StackWise Technology offers Stackable Resiliency
Cisco StackWise technology is a stacking architecture optimized for Gigabit Ethernet. This
technology is designed to respond to additions, deletions, and redeployment while maintaining
constant performance. Cisco StackWise technology unites up to nine individual switches into
a single logical unit, using special stack-interconnect cables and stacking software. The individual
switches can be any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E Series
Switches. The stack behaves as a single switching unit that is managed by a master switch,
elected from one of the member switches. The master switch automatically creates and updates all
the switching and optional routing tables. A working stack can accept new members or delete old
ones without service interruption.
PRIMARY FEATURES AND BENEFITS
Ease of Use: “Plug-and-Play” Configuration
A working stack is self-managing and self-configuring. When switches are added or removed,
®
the master switch automatically loads the Cisco IOS Software revision running on the stack to
the new switch, loads the global configuration parameters, and updates all the routing tables to
reflect changes. Upgrades are applied universally and simultaneously to all members of the stack.
The Cisco Catalyst 3750 Series stacks up to nine switches as a single logical unit for a total of 468
Ethernet or PoE 10/100 ports, or 468 Ethernet 10/100/1000 ports or PoE 10/100/1000 ports, or
nine 10 Gigabit Ethernet ports. Additional port combinations can be created by connecting
the Cisco Catalyst 3750-E Series Switches to the stack. Individual 10/100, 10/100/1000, and 10
Gigabit Ethernet units can be joined in any combination to evolve with network needs.
Return on Investment Through Lower Operations Costs
The automatic Cisco IOS Software version checking and loading of the global configuration
parameters provide the first level of operational time saving. The second level is added during
the event of an outage. When you remove a troubled switch from an existing stack of switches and
replace it with another switch, the master switch will recognize this as a maintenance outage and
automatically reload the port-level configuration that was on the previous switch without user
intervention. This allows IT managers to have local personnel in remote locations perform
maintenance tasks instead of sending costly technicians out for a few minutes of work, thus saving
thousands of dollars in operational costs.

Data Sheet
Mix-and-Match Switch Types: Pay as You Expand Your Network
Stacks can be created with any combination of Cisco Catalyst 3750 and Cisco Catalyst 3750-E
switches. Customers who need a mixture of 10/100 and 10/100/1000 ports, PoE, and wiring-closet
aggregation capability can incrementally develop the access environment, paying only for what
they need. When uplink capacity needs to be increased, you can easily upgrade your bandwidth
by adding a 10 Gigabit Ethernet version to the stack and upgrade your Gigabit Ethernet links with
10 Gigabit Ethernet on the existing fiber.
Integrated Wireless LAN Controller
The Cisco Catalyst 3750G Integrated Wireless LAN Controller integrates wireless LAN controller
functions into the Cisco Catalyst 3750G Series Switches and delivers improved operating
efficiency and WLAN security, mobility, and ease of use for business-critical wireless LANs. The
Cisco Catalyst 3750G Integrated Wireless LAN Controller delivers centralized security policies,
wireless intrusion prevention system (IPS) capabilities, award-winning RF management, QoS, and
Layer 3 fast secure roaming for WLANs. As a core component of the Cisco Unified Wireless
Network, the Cisco Catalyst 3750G Integrated Wireless LAN Controller provides the control,
security, redundancy, and reliability that network managers need to scale and manage their
wireless networks as easily as they scale and manage their traditional wired networks.
Availability: Uninterrupted Performance at Layer 2 and Layer 3
The Cisco Catalyst 3750 Series increases availability for stackable switches. Each switch can
operate as both a master controller and a forwarding processor. Each switch in the stack can
serve as a master, creating a 1:N availability scheme for network control. In the unlikely event of a
single unit failure, all other units continue to forward traffic and maintain operation.
Smart Multicast: A New Level of Efficiency for Converged Networks
With Cisco StackWise technology, the Cisco Catalyst 3750 Series offers greater efficiency for
multicast applications such as video. Each data packet is put onto the backplane only once, which
provides more effective support for more data streams.
Superior Quality of Service Across the Stack and at Wire Speed
The Cisco Catalyst 3750-E and 3750 Series offer Gigabit and 10 Gigabit Ethernet speed with
intelligent services that keep everything flowing smoothly, even at 10 times the normal network
speed. Mechanisms for marking, classification, and scheduling deliver best-in-class performance
for data, voice, and video traffic, all at wire speed.
Network Security: Granular Control for the Access Environment
The Cisco Catalyst 3750 Series supports a comprehensive set of security features for connectivity
and access control, including ACLs, authentication, port-level security, and identity-based network
services with 802.1x and extensions. This set of comprehensive features not only helps prevent
external attacks, but also defends the network against “man-in-the-middle” attacks, a primary
concern in today’s business environment.
Single IP Management: Many Switches, One Address
Each Cisco Catalyst 3750 Series stack is managed as a single object and has a single IP address.
Single IP management is supported for activities such as fault detection, VLAN creation and
modification, network security, and QoS controls.

Jumbo Frames: Support for High-Demand Applications
The Cisco Catalyst 3750 Series supports jumbo frames on the 10/100/1000 configurations for
advanced data and video applications requiring very large frames. All Cisco Catalyst 3750-E
Series switch models also support jumbo frames.
IPv6 Support
The Cisco Catalyst 3750 Series supports IPv6 routing in hardware for maximum performance. As
network devices grow and the need for larger addressing and higher security becomes critical,
the Cisco Catalyst 3750 Series will be ready to meet the requirement.
Standard PoE Support: Graceful Addition of IP Communications
The Cisco Catalyst 3750 and 3750G PoE models support Cisco IP phones and Cisco Aironet
®
wireless LAN (WLAN) access points, as well as any IEEE 802.3af-compliant end device. The
Cisco Catalyst 3750 and 3750G 24-port versions can support 24 simultaneous full-powered PoE
ports at 15.4W for maximum powered device support. The 48-port versions can deliver the
necessary power to support 24 ports at 15.4W, 48 ports at 7.7W, or any combination in between.
10 Gigabit Ethernet Support: Increased Uplink Bandwidth for Gigabit Ethernet Deployments
The Cisco Catalyst 3750 Series allows network managers to incrementally add IEEE 802.3aecompliant 10 Gigabit Ethernet connectivity in their wiring closets or grid clusters, further facilitating
and enhancing Gigabit Ethernet networks. This provides investment protection to customers who
want to use their existing fiber plant, add uplink bandwidth capacity to their switching stacks, and
provide higher performance to applications and users. The Cisco Catalyst 3750-E Series offers
an even greater variety of 10 Gigabit Ethernet port configuration switches.
Management Options
The Cisco Catalyst 3750 Series (Figure 5) offers both a superior command-line interface (CLI) for
detailed configuration and Cisco Network Assistant Software, a Web-based tool for quick
configuration based on preset templates. In addition, CiscoWorks supports the Cisco Catalyst
3750 Series for networkwide management. Table 1 lists the features and benefits of the Cisco
Catalyst 3750 Series.

Power Connectors
● Customers can provide power to a switch by using either the internal power supply or a
redundant power system (Cisco RPS 2300 or the Cisco RPS 675). The connectors are
located at the back of the switch.
● Internal power supply connector
● The internal power supply is an autoranging unit.
● The internal power supply supports input voltages between 100 and 240VAC.
● Use the supplied AC power cord to connect the AC power connector to an AC power outlet.
● Cisco RPS Connector
● The connector offers connection for an optional Cisco RPS 2300 or RPS 675 that uses AC
input and supplies DC output to the switch.
● The connector automatically senses when the internal power supply of a connected device
fails and provides power to the failed device, preventing loss of network traffic.
● Only the Cisco RPS 2300 (model PWR-RPS2300) or the Cisco RPS 675 (PWR675-AC-RPSN1=) should be attached to the redundant-power-supply receptacle.
Indicators
● Per-port status LEDs: link integrity, disabled, activity, speed, and full-duplex indications
● System-status LEDs: system, RPS, and bandwidth-utilization indications
