Tipas

Valdomi (managed) komutatoriai suteikia galimybę valdyti duomenų perdavimą vidiniame tinkle bei jų valdymą.

Nevaldomi komutatoriai tiesiog suteikia galimybę dviems įrenginiams, Ethernet jungties pagalba, pvz., kompiuteriui ir spausdintuvui sąveikauti. Įprastai tokio tipo įrenginiai vadinami «Plug-and-Play».

Managed
Base T jungčių skaičius

26
Jungčių tipas

LAN arba Ethernet jungtis tinklo kabeliui pajungti.

10/100 MB/s standartinis greitis, kuris būdingas beveik visiems maršrutizatoriams.

10/100/1000 MB/s arba GigaBit standartas dešimt kartų greitesnis, kuris kartu su Gigabit LAN tinklo plokštės pagalba leidžia vidiniame kompiuterių tinkle duomenis perduoti itin greitai. Toks sprendimas yra būtinas biuruose, kur tarp kompiuterių reikia dažnai nukopijuoti didelės apimties failus arba reikalingas spartus plačiajuostis interneto ryšys (su ~30 Mb/s) keliuose kompiuteriuose vienu metu.

Features and Benefits

Cisco 300 Series Switches provide security, performance, traffic management, and other capabilities - optimized and customized, and at the right price for small businesses. The Cisco 300 Series provides:

High performance and reliability
Cisco 300 Series Switches have been rigorously tested to deliver the high availability and performance you expect from a Cisco switch. The solutions speed up file transfer times and improve slow, sluggish networks, while keeping your vital business applications available and preventing costly downtime. As a managed switching solution, the Cisco 300 Series also gives you the flexibility to manage and prioritize high-bandwidth traffic such as voice. That means you can empower your employees with state-of-the-art communication and productivity solutions, without draining the performance of your other business applications.

Fast, easy setup and configuration
Cisco 300 Series Switches are designed to be easy to use and manage by small businesses and the partners who serve them. The included device manager software provides an intuitive, web-based interface to simplify setup, security, and quality of service (QoS) traffic prioritization, allowing even users without IT expertise to configure the switch in minutes. Cisco also provides a Cisco FindIT Network Discovery Utility. This utility that works through a simple toolbar on the user's web browser to discover Cisco devices in the network and display basic information, such as serial numbers and IP addresses, to aid in the configuration and deployment of Cisco Small Business products. These switches use Cisco Discovery Protocol as well as Link Layer Discovery Protocol (LLDP-MED) to automatically detect all the devices connected to your network, and then automatically configure themselves for the appropriate connectivity and instructs the devices to use appropriate voice VLAN or QoS parameters. For more advanced capabilities and hands-on control, the switches support Smartport roles which configure the ports with specific levels of Security, QoS, and availability according to the type of connected device, based on Cisco best practices and pretested configurations. The Auto Smartports feature applies the intelligence delivered through the Smartport roles and applies it automatically to the port based on the devices discovered over CDP or LLDP-MED. This facilitates zero touch deployments. Although the Cisco 300 Series is designed to be deployed without using a command-line interface (CLI), Cisco Textview is available for those who prefer to use text-based configuration. Together, these features reduce the time your staff must devote to network deployment, management, and troubleshooting.

Strong security
The Cisco 300 Series Switches provide a high level of security and give you fine-grained control to safeguard your network from unauthorized users. Advanced security features include:
– Embedded security to protect management data traveling to and from the switch and encrypt network communications
– Extensive access control lists (ACLs) to restrict sensitive portions of the network from unauthorized users and guard against network attacks
– Guest virtual LANs (VLANs) to 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 to tightly limit access to specific segments of your network
– Security mechanisms such as, Bridge Protocol Data Unit (BPDU) Guard and broadcast/multicast/unknown unicast storm control, protect the network from invalid configurations or malicious intent.
– Secure Core Technology (SCT) helps ensure that the switch will receive and process management and protocol traffic no matter how much traffic is received.

Power over Ethernet
Cisco 300 Series Switches are available with up to 48 PoE ports of Fast Ethernet or 28 PoE ports of Gigabit Ethernet connectivity. This capability simplifies advanced technology deployments such as IP telephony, wireless, and IP surveillance by allowing you to connect and power network endpoints over a single Ethernet cable. With no need to install separate power supplies for IP phones or wireless access points, you can take advantage of advanced communications technologies more quickly, and at a lower cost.

IP telephony support
Cisco 300 Series Switches include embedded QoS intelligence to prioritize delay-sensitive services such as voice and video, simplify unified communications deployments, and help ensure consistent network performance for all services. 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.

Advanced network management capabilities
As managed switches, the Cisco 300 Series lets you use a variety of advanced features to control traffic over your network. Features include:
– Static routing/Layer 3 switching between VLANs: This capability allows you to segment your network into separate workgroups and communicate across VLANs without degrading application performance. As a result, you can manage internal routing with your switches and dedicate your router to external traffic and security, helping your network run more efficiently.
– IPv6 support: As the IP network addressing scheme evolves to accommodate more devices, you can make sure that your network is ready. The Cisco 300 Series provides native support for IPv6, the newest version of the Internet Protocol, as well as the previous IPv4 standard. As a result, you will be able to move up to the next generation of networking applications and operating systems without an extensive equipment upgrade.
– Dual image support: With the ability to maintain dual images of your switches, you can perform software upgrades without having to take the network offline and without worrying about an outage during an upgrade.
– Remote management: Using Simple Network Management Protocol (SNMP), you can set up and manage all switches and other Cisco devices in your network remotely, instead of having to directly connect to them.

Optimal energy efficiency
Cisco 300 Series Switches are designed with a variety of power-saving features across all models, providing the industry's broadest portfolio of "green" switches. These switches optimize power use to protect the environment and reduce energy costs, without compromising performance. Power-saving features include:
– The latest application-specific integrated circuits (ASICs), using low-power 65-nanometer technology (these chipsets allow for lower power consumption and thinner, more efficient designs)
– Automatic power shutoff on PoE ports when a link is down
– Embedded intelligence to adjust signal strength based on cable length
– Fanless design in most models, which reduces power consumption, increases reliability, and provides quieter operation

Expansion ports
The Cisco 300 Series provides more ports per Gigabit Ethernet switch than traditional switch models, giving you more flexibility to connect and empower your business. Gigabit Ethernet models feature 28- and 52-port switches, versus traditional devices that offer 20 or 44 ports with four shared ports giving you more value. The Cisco 300 Series also offers mini gigabit interface converter (mini-GBIC) 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.

Multiple languages
The Cisco 300 Series is available in seven languages: English, French, German, Italian, Spanish, Japanese, and simplified Chinese. All product user interfaces and documentation are translated, giving you the ability to select your preferred language.

Peace of mind and investment protection
Cisco 300 Series Switches offer the reliable performance, investment protection, and peace of mind you expect from a Cisco switch. When you invest in the Cisco 300 Series, you gain the benefit of:
– Cisco limited lifetime warranty with next business day advance replacement (where available)
