Cisco Small Business Pro ESW 500 Series Switches

A Cost-Effective, High-Performance Network Foundation to Keep Your Business Moving

In a world that never slows down, your business needs to keep moving. That means keeping employees connected at all times--to each other and to the business applications they need to do their jobs. Imagine a network that provides a single, high-performance platform for all of your business applications. Where your employees don’t have to worry about reduced productivity because the network is down or because a vital application is unavailable or running too slowly. Imagine being able to manage your entire network platform from a single interface, and being able to easily add new data, voice, video, and wireless applications as your business evolves.

Cisco offers a network solution for small businesses that can make this vision a reality. The Cisco® ESW 500 Series Switches are cost-effective, easy-to-use switches that provide the foundation of your small business network. These high-performance switches deliver the reliability you need to keep your employees connected and productive, preserving the availability of your essential applications and services to keep your business moving.

Cisco ESW 500 Series Switches:

The Cisco ESW 500 Series, part of the Cisco Small Business Pro Series, is a group of managed Ethernet switches that provide wire-speed Fast Ethernet and Gigabit Ethernet connectivity, integrated security, quality of service (QoS), and Power over Ethernet (PoE) to support all of your business network needs. These switches integrate easily with Cisco Small Business Pro products as well as the Cisco Smart Business Communications System to provide a complete data, voice, video, and wireless networking solution for your business. With the Cisco ESW 500 Series, you can take advantage of a proven network solution and a broad portfolio of high-performance, easy-to-manage switches that are designed and priced for small businesses.

Features and Benefits:

The Cisco ESW 500 Series switches provide security, management, and other capabilities far beyond what unmanaged or “smart” switches can provide, without requiring you to configure (or pay for) features you don’t need. The switches were designed to be part of the complete line of Small Business Pro networking and voice communications products that work together as part of proven, fully integrated, easy-to-use small business solution. The Cisco ESW 500 Series provides:

• Outstanding performance: The Cisco ESW 500 Series supports up to Gigabit Ethernet speeds to deliver optimal network performance, enabling you to add high-bandwidth data, voice, video, and wireless applications. Ultimately, the switches give you the ability to meet more rigorous application demands and help ensure that your employees always have access to the tools they need to be responsive to your customers and each other.
• High reliability: Cisco ESW 500 Series Switches have been developed and rigorously tested to provide reliable connectivity and performance, especially when supporting advanced voice, video, and wireless services. They also support an optional redundant power supply that provides uninterrupted failover to help ensure continuous operation, without the need to reboot, even if the primary power supply fails. These features help you keep your network available, prevent costly downtime, and keep your employees and customers connected to the applications they need.
• Power over Ethernet: Cisco ESW 500 Series Switches are available with up to 48 PoE ports of Fast Ethernet and 24 PoE ports of Gigabit Ethernet connectivity. PoE allows you to power network-attached devices such as IP phones, video cameras, and wireless access points directly over the Ethernet connection, without an external power supply. The result is a simpler and less expensive deployment, without the need to install a separate power supply for each connected endpoint.
• Quality of service: Cisco ESW 500 Series Switches feature QoS intelligence to prioritize delay-sensitive and high-bandwidth network traffic, enhancing network performance and allowing businesses to support demanding services such as real-time voice and video.
• Simple configuration and management: Cisco ESW 500 Series Switches are designed to be configured and managed by small businesses or the Cisco partners that serve them. Whether you are installing a single switch or an advanced voice and video communications system, simple graphical user interfaces (GUIs) help your staff easily configure, manage, and troubleshoot your network. The Cisco ESW 500 Series includes an embedded web based Configuration Utility Device Manager designed specifically for setting up the ESW 500 switch (Figure 3).

Figure 3. Cisco ESW 500 Configuration Utility Device Manager

For system wide deployments, you can use the Cisco Configuration Assistant, a GUI-based application that configures all of the devices that are part of Small Business Pro Series as well as the Cisco Smart Business Communications System. Both the device manager and Cisco Configuration Assistant feature Cisco Discovery Protocol to automatically discover all Cisco devices and allow them to share information about one another. They also employ Cisco Smartports technology, which provides preset options for quickly configuring all ports on a Cisco ESW 500 Series Switch, including QoS, and security features (Figure 4).

Once the network is deployed, Cisco Configuration Assistant can generate status reports, synchronize passwords, and upgrade software across all of your Cisco network devices. All of these features reduce the time and effort your staff must devote to network deployment and troubleshooting, so that they can focus on your business priorities. Support for the Cisco ESW 500 Series will be included in Cisco Configuration Assistant version 2.0, available in CY'09 Q2.

• Strong network security: Cisco ESW 500 Series Switches provide several layers of security to protect your business. Support for IEEE 802.1X port security can help ensure that only authorized users and applications can access your wired and wireless LAN. Access control lists (ACLs) can restrict access to sensitive portions of the network and guard against attacks by keeping unauthorized users from logging in. The Cisco ESW 500 Series also supports virtual LANs (VLANs) to segment traffic and workgroups, and MAC address notification features to allow administrators to track where and when users enter the network.
• Easy integration with the Cisco Smart Business Communications System: The Cisco ESW 500 Series was designed to integrate with the Cisco Smart Business Communications System (SBCS) to provide a complete data, voice, video, and wireless networking solution for your business. For example, the Cisco ESW 500 Series ships with a default configuration that allows for “plug-and-play” in a Cisco SBCS voice deployment. Simply connect an IP phone to the network, and it immediately powers up and gets a dial tone.
• Expansion ports: The Cisco ESW 500 Series offers Small Form-Factor Pluggable (SFP) expansion slots that give you the option to add fiber-optic or Gigabit Ethernet uplink connectivity to the switch. With the ability to increase the connectivity range of the switches, you have more flexibility to design your network around your unique business environment, and to easily connect switches on different floors or across the business.
• 5-year enhanced Cisco Warranty: Cisco ESW 500 Series Switches come with a 5-year limited hardware warranty that includes next-business-day advance hardware replacement where available, otherwise 10 business day advance hardware replacement. In addition, Cisco offers software application fixes for the duration of the warranty and telephone technical support, through the Cisco Small Business Support Center, at no charge for the first 90 days following the date of purchase. The warranty also features complimentary access for one year to online customer chat support during local business hours.

• Move beyond your traditional phone system: The Cisco Smart Business Communications System lets you transform your business by bringing together all of your communications onto a single network. The Cisco ESW 500 Series works hand in hand with other Cisco Smart Business Communications System products, such as the Cisco Unified Communications 500 Series for Small Business. Together, the solution lets you support all of your company’s phone calls, messaging, and data. Your employees can be more productive, and you can save money by managing and paying for just one network.
  
• Securely extend network access with wireless: The Cisco ESW 500 Series Switches with PoE can connect and power your wireless access points while supporting robust security and identity services to protect your wireless environment. By choosing Cisco ESW 500 Series Switches with both PoE and Gigabit Ethernet connectivity, you can support new wireless technologies such as 802.11n and extend the life of your wireless technology investment.
  
• Connect your small business: The Cisco ESW 500 Series Switches meet the needs of a range of small businesses.
