Cisco Catalyst 3750-E Software
Cisco Catalyst 3750-E Series is available with either the IP Base or the IP Services feature set. The IP Base feature
set includes advanced quality of service (QoS), a suite of security features, rate-limiting, access control lists, basic
static, Routing Information Protocol (RIP), and OSPF routing capability. The IP Services feature set provides a richer
set of enterprise-class features, including advanced hardware-based IP unicast and multicast routing—Enhanced
Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP),
Protocol Independent Multicast (PIM), and IPv6 routing such as OSPFv3 and EIGRPv6.
Customers can transparently upgrade the software feature set in the Cisco Catalyst 3750-E Series Switches through
Cisco IOS
®
Software Activation. Software activation authorizes and enables the Cisco IOS Software feature sets. A
special file contained in the switch, called a license file, is examined by Cisco IOS Software when the switch is
powered on. Based on the license’s type, Cisco IOS Software activates the appropriate feature set. License types
can be changed, or upgraded, to activate a different feature set. For detailed information about Software Activation,

Investment Protection
The Cisco Catalyst 3750-E Series Switches are compatible with the Cisco Catalyst 3750 Series Switches, enabling
customers to stack them together and thereby protect existing investment in the Cisco Catalyst 3750 Series
Switches. The Cisco TwinGig Small Form-Factor Pluggable (SFP) converter module further protects customers’
investment in Cisco Catalyst 3750-E Series Switches by enabling migration from Gigabit Ethernet to 10 Gigabit
Ethernet uplinks, as business needs require, without having to upgrade the switches.
Cisco StackWise Plus Technology
Cisco StackWise Plus technology is built on the highly successful StackWise
™
technology, which is a premium
stacking architecture optimized for Gigabit Ethernet. StackWise technology was designed to respond to additions,
deletions, and redeployment while maintaining constant performance. 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. StackWise creates a highly resilient single unified system of up to nine
switches, providing simplified management using a single IP address, single telnet session, single command-line
interface (CLI), auto-version checking, autoconfiguration, and more. StackWise Plus supports all the features of
StackWise and provides backward compatibility with the existing Cisco Catalyst 3750 Series Switches while
enhancing the throughput of the system up to 64 Gbps. StackWise Plus also enables local switching in Cisco
Catalyst 3750-E Series Switches. Local switching packets coming into a port in the Cisco Catalyst 3750-E Series
Switch destined for another port in the same switch do not have to traverse through the stack ring, thus increasing
the forwarding capacity of the switch.
Cisco EnergyWise Technology
Cisco EnergyWise is an innovative architecture, added to the Cisco Catalyst 3750-E switches, promoting
companywide sustainability by reducing energy consumption across an entire corporate infrastructure and affecting
more than 50 percent of global greenhouse gas emissions created by worldwide building infrastructure, a much
greater effect than the 2 percent generated by the IT industry. Cisco EnergyWise enables companies to measure the
power consumption of network infrastructure and network-attached devices and manage power consumption with
specific policies, reducing power consumption to realize increased cost savings, potentially affecting any powered
device.

EnergyWise encompasses a highly intelligent network-based approach to communicate messages that measure
and control energy between network devices and endpoints. The network discovers Cisco EnergyWise manageable
devices, monitors their power consumption, and takes action based on business rules to reduce power consumption.
EnergyWise uses a unique domain-naming system to query and summarize information from large sets of devices,
making it simpler than traditional network management capabilities. Cisco EnergyWise’s management interfaces
allow facilities and network management applications to communicate with endpoints and each other using the
network as a unifying fabric. The management interface uses standard SNMP or SSL to integrate Cisco and third-
party management systems.
Cisco EnergyWise extends the network as a platform for power control plane for gathering, managing, and reducing
power consumption of all devices, resulting in companywide optimized power delivery and reduced energy costs.
10 Gigabit Ethernet Uplinks and the Cisco TwinGig SFP Converter
The Cisco Catalyst 3750-E features wire-speed 10 Gigabit Ethernet uplink ports for high-bandwidth applications,
relieving congestion and helping ensure smooth delivery of data. The TwinGig SFP converter (see Figure 2) converts
a 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet SFP ports. This way, customers can initially use the
switch with Gigabit Ethernet uplinks and later implement 10 Gigabit Ethernet uplinks as business demands change,
without having to upgrade the access layer.

Modular Power Supplies
The Cisco Catalyst 3750-E Series Switches have one power supply slot and support the following power supplies.
PoE switches require a PoE power supply. Data-only switches can operate with any of the power supplies.
●
C3K-PWR-1150WAC: 1150WAC power supply with 800W PoE
●
C3K-PWR-750WAC: 750WAC power supply for 24-port switch with 420W PoE
●
C3K-PWR-265WAC: 265WAC power supply for 48-port or 24-port switch without PoE
●
C3K-PWR-265WDC: 265WDC power supply for 48-port or 24-port switch without PoE
Maximum power availability for converged voice and data networks is attainable when a Cisco Catalyst 3750-E
Series Switch is combined with the Cisco RPS 2300 Redundant Power System for transparent protection against
internal power supply failures and an uninterruptible power supply (UPS) system to safeguard against power
outages. Using the RPS 2300 to provide backup power, the Cisco Catalyst 3750-E Series Switch power supplies
become hot swappable. Table 3 shows the power supply compatibility matrix.

Power over Ethernet
The Cisco Catalyst 3750-E Series can provide a lower total cost of ownership for deployments that incorporate Cisco
IP phones, Cisco Aironet
®
wireless LAN (WLAN) access points, or any IEEE 802.3af-compliant end device. PoE
removes the need for wall power to each PoE-enabled device and eliminates the cost for additional electrical cabling
and circuits that would otherwise be necessary in IP phone and WLAN deployments. The Cisco Catalyst 3750-E 24-
port PoE configurations can support 24 simultaneous full-powered PoE ports at 15.4W for full powered-device
support. The Cisco Catalyst 3750-E 48-port PoE configurations can support 48 simultaneous full-powered PoE ports
at 15.4W when using the optional 1150W power supply. Alternatively, for deployments that do not need full PoE on
all ports, a smaller power supply can be used in conjunction with Cisco Catalyst Intelligent Power Management to
support 24-port and 48-port PoE configurations.
In addition, Cisco Catalyst Intelligent Power Management supports Enhanced PoE where up to 20W of PoE can be
delivered to each port. This capability enables support of PoE devices such as 802.11n wireless equipment where
>15.4W of PoE is required.
Redundant Power System
The Cisco Catalyst 3750-E Series Switches support the new generation of Redundant Power Supply (RPS) 2300.
The RPS 2300 increases availability in a converged data, voice, and video network by providing transparent power
backup to two of six attached Cisco Catalyst 3750-E Series Switches at the same time. The failed power supply can
be swapped out while the switch is being powered up by the RPS 2300.
Primary Features and Benefits
Ease of Use: Deployment
A working stack is self-managing and self-configuring. When switches are added or removed, the master switch
automatically loads the Cisco IOS Software version 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-E Series stacks up to nine switches as a single logical unit for a total of 468 Ethernet
10/100/1000 ports, 432 PoE 10/100/1000 ports, or 18 10 Gigabit Ethernet ports. Individual 10/100/1000 units can be
joined in any combination to evolve with network needs.
Other ease of use features include but are not limited to:
●
Smartports enable fast and easy configuration of Cisco recommended best practice security and QoS
features, encapsulating years of Cisco networking expertise.
●
Dynamic Host Configuration Protocol (DHCP) autoconfiguration of multiple switches through a boot server
eases switch deployment.
●
Automatic QoS (AutoQoS) simplifies QoS configuration in voice over IP (VoIP) networks by issuing interface
and global switch commands to detect Cisco IP phones, classify traffic, and help enable egress queue
configuration.
●
Master configuration management helps ensure that all switches are automatically upgraded when the
master switch receives a new software version. Automatic software version checking and updating help
ensure that all stack members have the same software version.
●
Autonegotiation on all ports automatically selects half- or full-duplex transmission mode to optimize
bandwidth.
●
Dynamic Trunking Protocol (DTP) facilitates dynamic trunk configuration across all switch ports.
