Introduction
The
new Cisco Catalyst 3750 Series switches are
an innovative product line that improves LAN
operating efficiency by combining industry-leading
ease of use and the highest resiliency available
for stackable switches. This new product series
represents the next generation in desktop
switches, and features Cisco StackWise technology,
a 32-Gbps stack interconnect that allows customers
to build a unified, highly resilient switching
systemone switch at a time.
For
mid-sized organizations and enterprise branch
offices, the Cisco Catalyst 3750 Series eases
deployment of converged applications and adapts
to changing business needs by providing configuration
flexibility, support for converged network
patterns, and automation of intelligent network-services
configurations. In addition, the Cisco Catalyst
3750 Series is optimized for high-density
Gigabit Ethernet deployments and includes
a diverse range of switches that meet access,
aggregation, or small-network backbone-connectivity
requirements.

Cisco Catalyst 3750 Series is available in
the Standard Multilayer Software Image (SMI)
or the Enhanced Multilayer Software Image
(EMI). The SMI feature set includes advanced
quality of service (QoS), rate-limiting, access
control lists (ACLs), and basic static and
routed information protocol (RIP) routing
functionality. The EMI provides a richer set
of enterprise-class features including advanced
hardware-based IP unicast and multicast routing.
Cisco StackWise Technology—A New Standard
in Stackable Resiliency
Cisco StackWise technology is a premium 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 Cisco Catalyst 3750 switches into
a single logical unit, using special stack
interconnect cables and stacking software.
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.
Key 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 updates all the routing
tables to reflect changes. Upgrades are applied
universally and simultaneously to all members
of the stack.
Scalability—Fast Ethernet to Gigabit
Ethernet
The Cisco Catalyst 3750 Series stacks up to
9 switches as a single logical unit for a
total of 468 Ethernet 10/100 ports or 252
Ethernet 10/100/1000 ports. Individual 10/100
and 10/100/1000 units may be joined in any
combination to evolve with network needs.
Mix-and-Match Switch Types—Pay as You
Expand Your Network
Stacks can be created with any combination
of Cisco Catalyst 3750 switches. Customers
who need a mixture of
10/100, 10/100/1000 ports and wiring closet
aggregation capability can incrementally develop
the access environment, paying only for what
they need.
Availability—Non-Stop Performance at
Layer 2 and Layer 3
The Cisco Catalyst 3750 Series increases availability
for stackable switches. Each switch can operate
both as master controller and forwarding processor.
Each switch in the stack can serve as a master,
creating an 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 on to 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 Series offers Gigabit
Ethernet speed with intelligent services that
keep everything flowing smoothly—even
at ten times normal network speed. Industry-leading
mechanisms for marking, classification, and
scheduling deliver best-in-class performance
for data, voice, and video traffic—all
at wire speed.
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.
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, virtual LAN creation
and modification, 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.
IPv6 Capable—Getting Ready For The Future
The Catalyst 3750 supports IPv6 routing in
hardware for maximum performance. As network
devices grow and the need for larger
addressing and higher security become necessary,
the Catalyst 3750 will be ready to meet the
requirement.
Management Options
The Cisco Catalyst 3750 Series offers both
a superior command-line interface (CLI) for
detailed configuration and Cisco Cluster Management
Suite (CMS) Software, a Web-based tool for
quick configuration based on pre-set templates.
In addition, CiscoWorks supports the Cisco
Catalyst 3750 Series for network-wide management.

| Power
connectors |
Customers can provide power
to a switch by using either
the internal power supply 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 auto-ranging unit.
- The
internal power supply supports
input voltages between 100
and 240 volts alternating
current (VAC).
- Use
the supplied alternating-current
(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
675 that uses AC input and
supplies direct-current
(DC) output to the switch.
- The
connector offers a 675-watt
(W) RPS that supports up
to 6 external network devices
and provides power to 1
failed device at a time.
- 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 675 (model
PWR675-AC-RPS-N1=) should
be attached to the redundant-power-supply
receptacle.
