Description
Advanced Management Features
The SF220-48P-K9 is a managed switch that offers advanced management features for small businesses. Some of the key features include:
- 48 Gigabit Ethernet ports, with PoE support for powering devices like IP phones and cameras
- Quality of Service (QoS) for prioritizing different types of network traffic
- Access control lists (ACLs) for security and policy enforcement
- Link Aggregation Control Protocol (LACP) for increased bandwidth and redundancy
- Simple Network Management Protocol (SNMP) for monitoring and managing the switch remotely
- Web-based GUI and command-line interface (CLI) for configuring and managing the switch
- Cisco Discovery Protocol (CDP) for discovering and mapping other Cisco devices on the network
These advanced management features allow for greater control and visibility over the network, making it easier to ensure that critical applications and devices are given priority, and to secure and monitor the network.
Power Options and Redundancy
The SF220-48P-K9 Small Business Smart Plus SF220-48P 48 PoE Ethernet Ports Managed Switch provides several power options and redundancy features to ensure reliable operation.
- Power over Ethernet (PoE): The switch supports PoE on all 48 ports, providing up to 30W per port for powering devices such as IP phones, wireless access points, and cameras. This eliminates the need for separate power supplies for PoE devices, reducing clutter and simplifying deployment.
- Dual internal power supplies: The switch features dual internal power supplies that provide redundancy in case of a power supply failure. In the event of a failure, the switch will continue to operate using the remaining power supply, minimizing disruptions to network operations.
- Redundant Power System (RPS) support: The switch also supports RPS, which allows for connecting an external RPS device to provide redundancy for the switch’s power supply. This can provide additional protection against power failures, ensuring that the switch remains operational even in the event of a power outage.
- Automatic power recovery: The switch has an Automatic Power Recovery feature that automatically restores power to the switch upon power failure. This feature helps ensure that the switch is quickly restored to normal operation after a power failure.
Expandability and Scalability
The SF220-48P-K9 Small Business Smart Plus SF220-48P 48 PoE Ethernet Ports Managed Switch is designed to be expandable and scalable to meet the evolving needs of small businesses.
- Stackable: The switch supports stacking, which allows multiple switches to be connected together to form a single, logical switch. This can provide increased capacity and redundancy, allowing the network to grow as the business expands. Up to 8 SF220-48P-K9 switches can be stacked together to increase the number of ports available.
- Link aggregation: The switch supports Link Aggregation Control Protocol (LACP) which allows for grouping multiple physical ports together to form a single, logical link. This can provide increased bandwidth and redundancy, allowing the network to handle more traffic and providing more resilience against link failures.
- VLANs: The switch supports Virtual Local Area Networks (VLANs) which allow for segmenting the network into different logical networks. This can provide increased security and better traffic management, allowing the network to handle more devices and applications.
- Quality of Service (QoS): The switch supports Quality of Service (QoS) which allows for prioritizing different types of network traffic. This can ensure that critical applications and devices are given priority, allowing the network to handle more traffic and providing a better user experience.
- Firmware Upgrade: The switch can be upgraded with new firmware releases, which can provide new features and capabilities, allowing the switch to adapt to changing network requirements.
All these features make SF220-48P-K9 Small Business Smart Plus SF220-48P 48 PoE Ethernet Ports Managed Switch a scalable and expandable option for small businesses looking for a reliable and cost-effective network switch solution.
