Eight (8) 10/100/1000 Gigabit Copper ports (port 8 with PoE+ power input support).
QoS features to prioritise delay-sensitive services such as voice and video.
Fanless design, which reduces power consumption, increases reliability, and provides quieter operation.
Layer 3 static routing allows you to segment your network into separate workgroups and communicate across VLANs.
Conserve energy by optimising power use, which helps protect the environment and lowers your energy costs.
Embedded Secure Sockets Layer (SSL) encryption to protect management data.
Includes support for Simple Network Management Protocol (SNMP).
Native support for IPv6 alongside traditional IPv4
Affordable Smart Switch
The Cisco SG250-08 8-Port switch is part of the next generation of affordable smart switches that combine powerful network performance and reliability with a complete suite of the network features you need for a solid business network. This powerful Gigabit Ethernet switch provides multiple management options, sophisticated security capabilities, fine-tuned Quality-of-Service (QoS) and Layer 3 static routing features far beyond those of an unmanaged or consumer-grade switch, at a lower cost than for fully managed switches.

Business Applications
Whether you need basic, high-speed connectivity for your computers and servers or a comprehensive voice, data, and wireless technology solution, the Cisco SG250-08 switch can meet your business needs. Possible deployment scenarios include:
  • High-speed desktop connectivity - This switch can quickly and securely connect employees working in small offices with one another and with all of the printers, servers, and other devices they use. High performance and reliable connectivity help speed up file transfers and data processing, improve network uptime, and keep your employees productive.
  • Flexible wireless connectivity - The Cisco SG250-08 switch works with Cisco and third-party wireless solutions to extend the reach of your network. With security features, VLAN, and QoS, this switch is the perfect foundation to add business-grade wireless to a network.
  • Unified communications - Provides QoS features to enable you to prioritise delay-sensitive traffic in your network and let you converge all of your communications solutions such as IP telephony and video surveillance onto a single Ethernet network. Cisco offers a complete portfolio of IP telephony and other unified communications products designed for small businesses, rigorous testing has been completed to help ensure easy integration and full compatibility with these and other vendor products.
Easy configuration and management
The Cisco SG250-08 8-Port switch is designed to be easily deployed and used by small businesses or the partners that serve them:
  • Smart Network Application (SNA) is an innovative network-level monitoring and management tool embedded in the Cisco 100 to 500 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. The Cisco SG250-08 switch supports the embedded FindIT Network Probe, eliminating the need to set up a separate hardware or virtual machine on site.
  • 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.
  • Simple or advanced-mode graphic user interfaces reduce the time required to deploy, troubleshoot, and manage the network. Configuration wizards simplify the most common configuration tasks and provide the ultimate tool for anyone to set up and manage the network.
  • Cisco Smartports technology provides more advanced capabilities and hands-on control by automatically configuring 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 automatically applies the intelligence delivered through the Smartports roles to the port based on the device types discovered over Cisco Discovery Protocol or LLDP-MED. This capability facilitates zero-touch deployments.
  • The USB port on the front panel of the switch enables easy image and configuration transfer for faster deployment or upgrades.
Reliability and Performance
The Cisco SG250-08 8-Port managed switch has been tested to deliver the high performance and reliability you would expect from a Cisco switch and help you prevent costly downtime. The switch speeds up file transfer times, improve slow and sluggish networks, keep your vital business applications available, and help your employees respond more quickly to customers and each other. With a network based on Cisco 250 Series switches like the SG250-08, you can address all of your business communications and connectivity needs and reduce the total cost of ownership of your technology infrastructure.

Layer 3 Static Routing
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 switch and dedicate your router to external traffic and security, helping your network run more efficiently.

Network Security
The Cisco SG250-08 Managed switch provides the security and network management features you need to maintain a high level of security for your business, keep unauthorised users off the network, and protect your business data. This switch includes integrated network security to reduce the risk of a security breach, with IEEE 802.1X port security to control access to your network, Denial-of-Service (DoS) attack prevention to increase network uptime during an attack, and extensive Access Control Lists (ACLs) to protect sensitive portions of the network from unauthorised users and guard against network attacks.

IPv6 Support
As the IP network addressing scheme evolves to accommodate more devices, you can have peace of mind that your network is ready. The Cisco SG250-08 switch provides native support for IPv6 alongside traditional IPv4. With USGv6 and IPv6 Gold Logo certifications, this switch will enable you to take full advantage of IPv6-enabled operating systems and applications in the future, without having to upgrade your network equipment.

IP Telephony Support
Includes QoS features to priorities delay-sensitive services such as voice and video, simplify unified communications deployments, and help ensure consistent network performance for all services.

Network-wide Automatic Voice Deployment
Using a combination of Cisco Discovery Protocol, LLDP-MED, Auto Smartports, and Voice Services Discovery Protocol (VSDP, a unique, patented Cisco protocol), customers can deploy an end-to-end voice network dynamically. The switches in the network automatically converge into a single voice VLAN and set of 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 prioritise voice traffic.

An Energy-Efficient Solution
This switch is designed to be energy efficient and Eco-friendly without compromising performance. It helps to conserve energy by optimising power use, which helps protect the environment and lowers your energy costs. Power-saving features include:
  • 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
  • Automatic power shutoff on ports when a link is down
  • Embedded intelligence to adjust power based on cable length
  • Fanless design in most models, which reduces power consumption, increases reliability, and provides quieter operation
  • Ability to turn off LEDs to conserve power
