Advanced features for demanding environments at an affordable price
Your business is growing, and that means more customers, more opportunities, and more attention on your
company. The only problem: Your network was built for a smaller operation. As you add more devices,
applications, and users, your IT environment will become increasingly difficult and expensive to manage. Even
worse, as the network becomes more complex and overloaded, your users are likely to see sluggish
performance and even outages.
With customers and employees depending on your business more than ever before, a slow or unreliable
network is not an option. You need an IT backbone that provides excellent performance, nonstop availability,
and advanced security. The ideal network will be easy to manage, support advanced features that will grow
with your company, and be at a price that’s affordable.
Cisco 550X Series Stackable Managed Switches
The Cisco® 550X Series (Figure 1) are the next-generation stackable managed Ethernet switches that provide
the advanced capabilities and superior performance you need to support a more demanding network
environment at an affordable price. These switches incorporate fan and power hardware redundancy,
increasing overall network availability. The SG550X and SF550X models provide 24 or 48 ports of Gigabit
Ethernet and Fast Ethernet connectivity with 10 Gigabit uplinks. The SX550X models provide 12, 16, 24, or 48
ports of 10 Gigabit Ethernet with both copper and fiber connection options, providing a solid foundation for your
current business applications, as well as those you are planning for the future. At the same time, these switches
are easy to deploy and manage, without a large IT staff.
Figure 1.
Cisco 550X Series Stackable Managed Switches
Cisco 550X Series switches are designed to protect your technology investment as your business grows. Unlike
switches that claim to be stackable but have elements that are administered and troubleshot separately, the
Cisco 550X Series provides true stacking capability, allowing you to configure, manage, and troubleshoot
multiple physical switches as a single device and more easily expand your network.
A true stack delivers a unified data and control plane, in addition to a 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. The switches also protect your technology investment with an enhanced warranty, dedicated
technical support, and the ability to upgrade equipment in the future and receive credit for your Cisco 550X
Series switch. Overall, the Cisco 550X Series provides the ideal technology foundation for a growing business.
Cisco 550X 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 550X 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 the SX550X switches, you can easily and cost-effectively enable 10G connections to
servers and network storage devices with standard RJ-45 Ethernet cable. You can also connect your SG550X
access switches to the SX550X aggregation with 10G SFP+ fiber, building a high-performance backbone to
speed up the overall operation of your network.
High reliability and resiliency
In a growing business in which availability 24 hours a day, 7 days a week is critical, you need to assure that
employees and customers can always access the data and resources whenever they need. In these
environments, stackable switches can play an important role in minimizing downtime and improving network
resiliency. For example, if the master switch within a Cisco 550X Series stack fails, another switch takes over,
keeping your network up and running. You can also replace individual devices in the stack without taking your
whole network offline or affecting employee productivity.
The Cisco 550X Series is designed to deliver hardware redundancy at the lowest incremental cost. Power
redundancy is delivered with the Cisco RPS2300 external RPS system. If power to the switch is lost
(through loss of AC power or power supply failure), the switch will automatically, and instantaneously, obtain its
power from the RPS. This switchover occurs so quickly that there is no loss in traffic or reboot of the device. A
Cisco RPS2300 system can be connected to up to six 550X Series switches to provide redundancy. Cooling fan
redundancy is delivered through preinstalled N+1 configuration. A switch can fully support all its capabilities for
the life of the product with only N fans. If one of the fans fails, the spare fan automatically takes over, without
causing any downtime.
The Cisco 550X Series provides an additional layer of resiliency with support for the Virtual Router Redundancy
Protocol (VRRP). VRRP lets you extend the same resiliency that stacking provides for individual switches to
complete network domains. By running VRRP between two stacks, you can instantly cut over from one stack to
another in the event of a problem and continue operating even after a failure.
The Cisco 550X Series also supports dual images, allowing you to perform software upgrades without having to
worry about the network going down during the upgrade.
Cisco 550X Series switches support the Power over Ethernet Plus (PoE+) standard (IEEE 802.3at), providing up
to 30 watts per port. The switches also support 60W PoE on selected ports to power compact switches, highpower wireless access points, or connected lighting. The power is managed in a smart fashion such that only
the amount of power the endpoint needs 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.
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 550X
Series switches are also fully backward compatible with IEEE 802.11af PoE and Cisco legacy PoE protocols.
Power efficiency
The Cisco 550X 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 550X 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 28- or 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
●
Smart fans in which fan speed is automatically adjusted according to switch temperature to decrease
acoustic noise and save power
Advanced 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 550X 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 a maximum of 400 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 operates 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 cannot support.
Using standard 10G fiber or copper connections, the Cisco 550X Series supports both local and horizontal
stacking deployments and the flexibility of ring or chain topology. The switches also have the capability to use
link aggregation port as the stacking port, providing even higher stacking bandwidth for demanding
applications.
Cisco 550X Series switches are designed to be easy to use and manage by small and medium businesses,
commercial customers, or the partners that serve them. Features include the following:
●
Smart Network Application (SNA) is an innovative network-level monitoring and management tool
embedded in the Cisco 250 to 550X Series switches. It can discover network topology, display link
status, monitor events, apply configurations, and upgrade software images across multiple switches in
the network.
●
The FindIT Network Manager and Probe are designed to manage Cisco 100 to 500 Series switches,
routers, and wireless access points. They let you proactively manage the network instead of just reacting
to events. Cisco 550X Series switches support the embedded FindIT Network Probe, eliminating the
need to set up a separate hardware or virtual machine on site. For more information, visit
The FindIT Network Discovery Utility works through a simple toolbar on the user’s web browser to
discover Cisco devices on the network and display basic device information, inventory, and new
firmware updates to aid in the configuration and speed the deployment of Cisco Small Business
products. For more information, visit https://www.cisco.com/c/en/us/products/cloud-systems-
Simple and advanced mode graphic user interfaces reduce the time required to deploy, troubleshoot,
and manage the network and allow you to support sophisticated capabilities without increasing IT head
count.
●
Configuration wizards simplify the most common configuration tasks and provide the ultimate tool for
anyone to easily set up and manage the network.
●
The switches also support Textview, a full Command-Line Interface (CLI) option for customers or
partners that prefer it.
●
Using Auto Smart ports intelligence, the switch can detect a network device connected to any port and
automatically configure the optimal security, Quality of Service (QoS), and availability on that port.
●
Cisco Discovery Protocol discovers Cisco devices and allows devices to share critical configuration
information, simplifying network setup and integration.
●
Support for Simple Network Management Protocol (SNMP) allows you to set up and manage your
switches and other Cisco devices remotely from a network management station, improving IT workflow
and mass configurations.
●
The USB port on the switch enables easy image and configuration transfer for faster deployment or
upgrade.
Cisco 550X Series switches help optimize your IT operations with built-in features that simplify day-to-day
network operation:
●
True stacking allows you to configure, manage, and troubleshoot multiple physical switches as a single
entity.
●
Unlike other stacking switches that require uniform configurations, the Cisco 550X Series allows you to
mix Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet models in a single stack, providing total
flexibility without sacrificing manageability.
●
Cisco switches use common chipsets/software across all switching portfolios, so all Cisco switches
within a series support the same feature set, making it easier to manage and support all switches across
the network.
Strong security
Cisco 550X 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 predesignated 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 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 is possible 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.
Advanced Layer 3 traffic management
The Cisco 550X Series enables a more advanced set of traffic management capabilities to help growing
businesses organize their networks more effectively and efficiently. For example, the switches provide static
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.
Additionally, the Cisco 550X Series provides dynamic Layer 3 routing features. These capabilities help you
minimize the need to manually configure routing devices and simplify the ongoing operation of the network.
IPv6 support
As the IP address scheme evolves to accommodate a growing number of network devices, the Cisco 550X
Series can support the transition to the next generation of networking and operating systems. 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 550X Series switches have successfully completed rigorous IPv6 testing and have received the
USGv6 and IPv6 Gold certification.
Networkwide automatic voice deployment
Using a combination of Cisco Discovery Protocol, LLDP-MED, Auto Smart ports, and Voice Services Discovery
Protocol (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.

An advanced technology backbone for growing businesses
Growth is never a bad thing. However, as you gain new customers and a higher profile, you need a business
technology platform capable of delivering a higher level of service and reliability. With more users, more
devices and applications, and more exposure to security threats, a switching platform designed for a smaller
operation simply cannot meet your growing needs. It’s time for a network that will support your business as you
take it to the next level. Cisco 550X Series switches provide the advanced feature set, reliability, and
investment protection your business needs, today and in the future.
