Managed Switch (24) port (10)g (SX550X-24FT-K9-EU)

Features and Benefits:

Cisco 550X Series switches provide the advanced feature set that growing businesses require and that high-bandwidth 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 SG550XG 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 SG550X access switches to the SG550XG 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 eliminating downtime and improving network resiliency. For example, if a switch within a Cisco 550X 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 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 take the network offline or worry about the network going down during the upgrade.

Power over Ethernet Plus (PoE+) and 60W PoE

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, high-power 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
