Cisco SG250-50P-K9-NA overview

  • 1Description

The Cisco SG250-50 250 Series Managed Switch is armed with 50 Gigabit Ethernet ports that connect multiple systems with one another and with printers, IP telephony devices, wireless access points, and other equipment. Cisco provides useful software-based tools to help in configuration and speed of deployment, and this managed switch allows detailed control over how data travels and who has access to the network. For performance, the SG250-50 switch has a 74.41 Mpps transfer rate and a 100 Gb/s switching capacity.

Cisco has designed 48 ports to be PoE+ compliant supporting 802.3af and 802.3at PoE network standards with a maximum PoE power budget of up to 375W. This feature allows PoE-compatible devices to run on a single connection that delivers data as well as up to 30W of power. To cool the switch, four fans are onboard and produce a maximum noise level of 50.2 dB.

The SG250-50 switch is equipped with two combo uplink ports that can utilize multimode and single-mode fiber connections, granting the switch a longer distance to another switch when compared to an Ethernet-based connection. Other notable features included with the switch are Layer 3 static routing for transmitting data between nodes without degrading networking performance along with IPv6 for supporting future applications without needing to upgrade networking equipment.

Easy Configuration and Management
  • Smart Network Application (SNA) is a 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 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 a helpful 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.
Performance
Cisco 220 Series switches speed up file transfer times, keep vital business applications available, and help your employees respond more quickly to customers and each other.
Layer 3 Static Routing
Layer 3 routing 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.
Power Over Ethernet Plus (PoE+)
Cisco 250 Series switches sport Gigabit Ethernet ports that are available with PoE+, which allows you to send data and power to network endpoints over a single network cable. This capability simplifies the deployment of IP telephony, wireless, video surveillance, and other solutions by eliminating the need for separate power supplies or outlets. PoE+ provides up to 30W of power per port, enabling deployments for 802.11ac wireless access points, Pan-Tilt-Zoom (PTZ) IP cameras, videophones, and thin client devices, delivering flexibility and investment protection.
Network Security
Cisco 250 Series switches provide the security and network management features you need to maintain a high level of security for your business, keep unauthorized users off the network, and protect your business data. The switches include 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 unauthorized users and guard against network attacks.
IPv6 Support
Cisco 250 Series switches provide native support for IPv6 alongside traditional IPv4. With USGv6 and IPv6 Gold Logo certifications, the 250 Series 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
Included QoS features prioritize delay-sensitive services such as voice and video, simplify unified communications deployments, and help ensure consistent network performance for all services.
Networkwide Automatic Voice Deployment
Using a combination of Cisco Discovery Protocol, LLDP-MED, Auto Smartports, and Voice Services Discovery 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 prioritize voice traffic.
Energy-Efficient Solution
Cisco 250 Series switches are designed to be energy efficient and ecofriendly without compromising performance. They help conserve energy by optimizing 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.
