Description
Scalable and Reliable Networking
The SF220-48-K9 Cisco Small Business Smart Plus SF220-48 is designed to provide scalable and reliable networking for small and medium-sized businesses. Some of its features that contribute to its scalability and reliability include:
- Link Aggregation Control Protocol (LACP): The switch supports LACP, which allows you to bundle multiple ports together to create a single, high-bandwidth link. This allows you to create redundant links between switches for increased reliability and bandwidth.
- Quality of Service (QoS): The switch supports QoS, which allows you to prioritize different types of traffic on your network. This can help to ensure that critical applications, such as VoIP and video streaming, receive the necessary bandwidth to function properly.
- VLANs: The switch supports VLANs, which allow you to segment your network into different logical segments. This allows you to isolate sensitive data or systems from the rest of the network, and also helps to improve network performance and security.
- SFP ports: The switch includes 48 SFP ports, which support fiber connectivity and can be used for uplinks to other switches or to connect to servers. This allows for a scalable and high-performance network design, as fiber connections are faster and more reliable than copper connections.
- Management: The switch can be managed through a web interface, SNMP (Simple Network Management Protocol), or through a command-line interface (CLI) using Telnet or SSH. This allows for easy management of the switch, and also allows for the switch to be integrated into an existing network management system.
- Energy efficient: The SF220-48-K9 supports Energy Efficient Ethernet (EEE) which reduces power consumption when the link is in low-utilization state, and also supports IEEE 802.3az Energy Efficient Ethernet (EEE) standard. This helps reducing the power consumption and also increase the overall network reliability.
Power Options and Redundancy
The SF220-48-K9 Cisco Small Business Smart Plus SF220-48 has several power options and redundancy features to ensure the switch is always available and running efficiently. These features include:
- PoE+: The switch supports PoE+ with a total power budget of 370W, allowing devices such as IP phones and wireless access points to be powered directly from the switch, eliminating the need for additional power supplies.
- Redundant power supply: The switch supports the use of a redundant power supply to ensure that the switch continues to operate even if one power supply fails. This provides additional reliability and uptime for the switch.
- Power over Ethernet (PoE) failover: The switch supports PoE failover, which allows for a secondary power supply to take over if the primary one fails. This provides additional reliability for PoE-powered devices connected to the switch.
- Power-saving features: The switch supports Energy Efficient Ethernet (EEE) which reduces power consumption when the link is in low-utilization state, and also supports IEEE 802.3az Energy Efficient Ethernet (EEE) standard. This helps reducing the power consumption and also increase the overall network reliability.
- Power-over-Ethernet Injection MIB: The SF220-48-K9 supports Power-over-Ethernet Injection MIB which allows monitoring of power budget and usage of the switch. This helps in monitoring the power usage and also to plan for power budget.
