Cisco 350X Series Stackable Managed Switches
Managed Switches That Provide the Ideal Combination of Features and Affordability
To stay ahead in a competitive marketplace, small businesses need to make every dollar count. That means
getting the most value from your technology investments, but it also means making sure that employees have fast,
reliable access to the business tools and information they need. Every minute an employee waits for an
unresponsive application – and every minute your network is down – has an impact on your bottom line. The
importance of maintaining a strong and dependable business network only grows as your business adds more
employees, applications, and network complexity.
When your business needs advanced security and features but value is still a top consideration, you’re ready for
the new generation of Cisco® Small Business managed switches: The Cisco 350X Series.

scalability, and ease of use because the stack of units operates as a single entity constituting all the ports of the
stack members. The switches also protect your technology investment with an enhanced warranty, dedicated
technical support, and the ability to upgrade equipment in the future. Overall, the Cisco 350X Series provides the
ideal technology foundation for a growing business.
Features and Benefits
Cisco 350X Series switches provide the advanced feature set that growing businesses require and that highbandwidth applications and technologies demand. These switches can improve the availability of your critical
applications, protect your business information, and optimize your network bandwidth to more effectively deliver
information and support applications. The switches provide the following benefits.
High-Performance 10 Gigabit Ethernet
Cisco 350X Series switches break the barrier of 10 Gigabit Ethernet adoption by providing affordable and flexible
configurations customized for the demanding network requirements of small and medium businesses.
With 10G copper ports on SG350XG switches, you can easily and cost-effectively enable 10G connections to
servers and network storage devices with standard RJ45 Ethernet cable. You can also connect your SG350X
access switches to the SG350XG aggregation with 10G SFP+ fiber connections, building a high-performance
backbone to speed up the overall operation of your network.
Multigigabit Performance
Network needs are changing quickly. Thanks to evolving wireless standards and the rising number of wireless
devices, keeping up with data rates and growing traffic can be a challenge. Your traditional Ethernet infrastructure
can support speeds up to 1 Gigabit per second (Gbps), but competing today requires much more capacity. One
option is completely replacing your older cabling infrastructure and upgrading your hardware. But wouldn’t it be
better to increase network speed and traffic capacity in a way that’s quick, inexpensive, and efficient?
Cisco’s new Multigigabit Ethernet switches offer just that: an easy-to-deploy, budget-friendly solution that allows
you to increase network speed and bandwidth using your existing cables. By partnering with other industry leaders
to form the NBASE-T Alliance, Cisco uses NBASE-T technology to help you get more out of your existing
infrastructure. Save time and money by avoiding upgrades and extending the life of your installed cable plants. And
discover the benefits of meeting consumer demand for increased bandwidth and speeds without a large initial
investment.
Multigigabit Ethernet technology uses capabilities in your existing cabling infrastructure to meet bandwidth
requirements and provide up to five times the performance. The technology enables intermediate data rates of 2.5
and 5 Gbps to ease the jump between traditional rates of 1 Gbps and 10 Gbps. These intermediate rates run on
most installed cables and preserve older UTP wiring, which is good for 802.11ac wireless LAN applications.
The technology also supports Power over Ethernet (PoE) forms, including PoE+ and 60W PoE. Cisco Multigigabit
Ethernet switches help you avoid having to run multiple cables between switches and access points and let your
networks welcome next-generation traffic speeds and data rates.

Power over Ethernet Plus (PoE+) and 60W PoE
PoE capabilities simplify the deployment of advanced technologies by allowing you to connect and power network
endpoints over a single Ethernet cable, without having to install separate power supplies. Cisco 350X Series
switches are also fully backward compatible with Cisco legacy PoE protocols.
Cisco 350X Series switches support the Power over Ethernet Plus (PoE+) standard (IEEE 802. at), providing up to
30 watts per port. The switches also support 60W PoE on select ports to power compact switches, high-power
wireless access points, or connected lighting. The PoE power is intelligently managed in a way such that only the
amount of power needed by endpoints is delivered to it and not wasted. As a result, the switches can support
devices that require more power, such as 802.11ac wireless access points, video-based IP phones, surveillance
cameras, and more.

High Reliability and Resiliency
In a growing business where availability 24 hours a day, 7 days a week is critical, you need to assure that
employees can always access the data and resources they need. In these environments, stackable switches can
play an important role in eliminating downtime and improving network resiliency. For example, if a switch within a
Cisco 350X Series stack fails, another switch immediately takes over, keeping your network up and running. You
can also replace individual devices in the stack without taking your network offline or affecting employee
productivity.
The Cisco 350X Series also supports dual images, allowing you to perform software upgrades without having to
take the network offline or worry about the network going down during the upgrade.
Simplified IT Operation
Cisco 350X Series switches help optimize your IT operations with built-in features that simplify and streamline dayto-day network operation:
●
True stacking allows you to troubleshoot, configure, and manage multiple physical switches as a single
entity.
●
Cisco switches use common chipsets/software across all switching portfolios, so all Cisco switches within a
category support the same feature set, making it easier to manage and support all switches across the
network.

True Stacking
Some switches claim to support stacking but in practice support only “clustering,” meaning that each switch must
still be managed and configured individually. Cisco 350X Series switches provide true stacking capability, allowing
you to configure, manage, and troubleshoot all switches in a stack as a single unit, with a single IP address, for up
to 4 units and a maximum of 208 Ethernet ports.
A true stack delivers a unified data and control plane, in addition to management plane, providing flexibility,
scalability, and ease of use because the stack of units operate as a single entity constituting all the ports of the
stack members. This capability can radically reduce complexity in a growing network environment while improving
the resiliency and availability of network applications. True stacking also provides other cost savings and
administrative benefits through features such as cross-stack QoS, VLANs, LAGs, and port mirroring, which
clustered switches can’t support.
Strong Security
Cisco 350X Series switches provide the advanced security features you need to protect your business data and
keep unauthorized users off the network:
●
Embedded Secure Sockets Layer (SSL) encryption protects management data traveling to and from the
switch.
●
Extensive Access Control Lists (ACLs) restrict sensitive portions of the network to keep out unauthorized
users and guard against network attacks.
●
Guest VLANs let you provide Internet connectivity to nonemployee users while isolating critical business
services from guest traffic.
●
Support for advanced network security applications such as IEEE 802.1X port security tightly limits access
to specific segments of your network. Web-based authentication provides a consistent interface to
authenticate all types of host devices and operating systems, without the complexity of deploying IEEE
802.1X clients on each endpoint.
●
Advanced defense mechanisms, including dynamic Address Resolution Protocol (ARP) inspection, IP
Source Guard, and Dynamic Host Configuration Protocol (DHCP) snooping, detect and block deliberate
network attacks. Combinations of these protocols are also referred to as IP-MAC port binding (IPMB).
●
IPv6 First Hop Security extends the advanced threat protection to IPv6. This comprehensive security suite
includes ND inspection, RA guard, DHCPv6 guard, and neighbor binding integrity check, providing
unparalleled protection against a vast range of address spoofing and man-in-the-middle attacks on IPv6
networks.
●
Time-based ACLs and port operation restrict access to the network during pre-designated times such as
business hours.
●
Uniform MAC address-based security can be applied automatically to mobile users as they roam between
wireless access points.
●
Secure Core Technology (SCT) helps ensure that the switch is able to process management traffic in the
face of a Denial-of-Service (DoS) attack.
●
Private VLAN Edge (PVE) provides Layer 2 isolation between devices on the same VLAN.
●
Storm control can be applied to broadcast, multicast, and unknown unicast traffic.

●
Protection of management sessions occurs using RADIUS, TACACS+, and local database authentication
as well as secure management sessions over SSL, SSH, and SNMPv3.
●
DoS attack prevention maximizes network uptime in the presence of an attack.
Networkwide Automatic Voice Deployment
Using a combination of Cisco Discovery Protocol, LLDP-MED, Auto Smartports, and Voice Services Discovery
Protocol (or VSDP, a unique Cisco protocol), customers can deploy an end-to-end voice network dynamically. The
switches in the network automatically converge around a single voice VLAN and QoS parameters and then
propagate them out to the phones on the ports, where they are discovered. For example, automated voice VLAN
capabilities let you plug any IP phone (including third-party phones) into your IP telephony network and receive an
immediate dial tone. The switch automatically configures the device with the right VLAN and QoS parameters to
prioritize voice traffic.
IPv6 Support
As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco 350X Series
can support the transition to the next generation of networking and operating systems such as Windows 7, Vista,
and Linux. These switches continue to support previous-generation IPv4, allowing you to evolve to the new IPv6
standard at your own pace, and helping ensure that your current network will continue to support your business
applications in the future. Cisco 350X Series switches have successfully completed rigorous IPv6 testing and have
received the USGv6 and IPv6 Gold certification.
Advanced Layer 3 Traffic Management
The Cisco 350X Series enables a more advanced set of traffic management capabilities to help growing
businesses organize their networks more effectively and efficiently. The switches provide static LAN Layer 3
routing, allowing you to segment your network into workgroups and communicate across VLANs without degrading
application performance. With these capabilities, you can boost the efficiency of your network by offloading internal
traffic-handling tasks from your router and allowing it to manage primarily external traffic and security. You can
minimize the need to manually configure routing devices and simplify the ongoing operation of the network.
Power Efficiency
The Cisco 350X Series integrates a variety of power-saving features across all models, providing the industry’s
most extensive energy-efficient switching portfolio. These switches are designed to conserve energy by optimizing
power use, which helps protects the environment and reduce your energy costs. They provide an eco-friendly
network solution without compromising performance. Cisco 350X Series switches feature:
●
Support for the Energy Efficient Ethernet (IEEE 802.3az) standard, which reduces energy consumption by
monitoring the amount of traffic on an active link and putting the link into a sleep state during quiet periods
●
The latest Application-Specific Integrated Circuits (ASICs), which use low-power 65/40-nanometer
technology and low-power, high-performance ARM CPUs
●
Automatic power shutoff on ports when a link is down
●
LEDs that can be turned off to save power
●
Embedded intelligence to adjust signal strength based on the length of the connecting cable
