High performance and reliability
All Cisco SG300-28MP 26-Port Gigabit 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 SG300-28MP also gives you the flexibility to manage and prioritise 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.
Power over Ethernet
Cisco SG300-28MP Switches are available with up to 24 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.
Secure Desktop Connectivity
The Cisco SG300-28MP Switch can simply and securely connect employees working in small offices with each other and with all of the servers, printers, and other devices they use. High performance and reliable connectivity helps speed file transfers and data processing, improves network uptime, and keeps your employees connected and productive. Additionally, the Cisco SG300-28MP Switch provides a high level of security and give you fine-grained control to safeguard your network from unauthorised users. Advanced security features include:
- Embedded security to protect management data traveling to and from the switch and encrypt network
- Extensive access control lists (ACLs) to restrict sensitive portions of the network from unauthorised 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
As a managed network solution, the Cisco SG300-28MP Switch provides the performance and advanced traffic-handling intelligence you need to deliver all communications and data over a single network. Cisco offers a complete portfolio of IP telephony and other unified communications products designed for small businesses. Cisco SG300-28MP Switchs have been rigorously tested to help ensure easy integration and full compatibility with these and other products, providing a complete small business solution.
IP Telephony Support
Cisco SG300-28MP Switches include embedded QoS intelligence to prioritise delaysensitive 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 prioritise voice traffic.
Highly Secure Guest Connectivity
A Cisco SG300-28MP Switch let you extend highly secure network connectivity to guests in a variety of settings, such as a hotel, an office waiting room, or any other area open to nonemployee users. Using powerful but easy-to-configure security and traffic segmentation capabilities, you can isolate your vital business traffic from guest services and keep guests’ network sessions private from each other.
Optimal Energy Efficiency
The Cisco SG300-28MP Switch is designed with a variety of power-saving features across all models, providing the industry’s broadest portfolio of “green” switches. These Cisco SG300-28MP Switches optimise power use to protect the environment and reduce energy costs, without compromising performance. Powersaving 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)
- Embedded intelligence to adjust signal strength based on cable length
- Bảo hành: 12 tháng.
