More Features

The SF350-48MP-K9 is a Cisco switch model that is part of the SF350 series. It is a managed switch, meaning it can be configured and monitored remotely using a web interface or through a network management system.

The model has 48 Ethernet ports, which support 10/100Mbps data speeds. These ports also have Power over Ethernet Plus (PoE+) capabilities, meaning they can supply power to devices connected to them, such as IP phones or wireless access points. This eliminates the need for separate power supplies for these devices.

The switch also provides a range of advanced features that are useful for small and medium-sized businesses. These include Virtual Local Area Networks (VLANs), which can segment a network into smaller, isolated groups for improved security and traffic management. Quality of Service (QoS) is also supported, which can prioritize different types of traffic to ensure that critical applications receive the necessary bandwidth. Additionally, the model provides a range of security features, such as 802.1X port-based authentication, to help protect the network from unauthorized access.

Power and Innovation

The SF350-48MP-K9 Cisco switch is designed to provide power and innovation to small and medium-sized businesses. One of its key features is its support for Power over Ethernet Plus (PoE+) technology, which allows the switch to supply power to devices connected to it, such as IP phones, wireless access points, and cameras. This eliminates the need for separate power supplies for these devices, which can help to reduce costs and improve the overall efficiency of the network.

The switch also provides a range of advanced features that are designed to improve the performance, security, and manageability of the network. For example, the switch supports Virtual Local Area Networks (VLANs), which can segment a network into smaller, isolated groups. This can help to improve security by isolating sensitive data and applications, as well as to improve traffic management by reducing congestion and optimizing the use of network resources.

The switch also supports Quality of Service (QoS) which can prioritize different types of traffic to ensure that critical applications receive the necessary bandwidth. This can help to improve the performance of the network and to ensure that important applications, such as VoIP or video conferencing, are always available and responsive.

The model also provides a range of security features, such as 802.1X port-based authentication, to help protect the network from unauthorized access. This can help to prevent data breaches and to protect sensitive information.

Compliant Standards

The model Cisco switch is compliant with a number of industry standards, which ensure that it is compatible with other devices and systems and that it meets certain performance and safety requirements.

Some of the compliant standards of SF350-48MP-K9 are:

  • IEEE 802.3: This standard defines the physical and data link layers of Ethernet, which is the most widely-used LAN technology.
  • IEEE 802.3u: This standard defines the Fast Ethernet specifications, which provide higher data rates (100Mbps) over traditional Ethernet (10Mbps).
  • IEEE 802.3ab: This standard defines the specifications for Gigabit Ethernet, which provides even higher data rates (1000Mbps) over Fast Ethernet.
  • IEEE 802.3af/at/bt: These standards define the specifications for Power over Ethernet (PoE), which allows devices to receive power over the Ethernet cable. PoE+ supports higher power requirements for devices such as wireless access points and IP cameras.
  • IEEE 802.1Q: This standard defines the Virtual LAN (VLAN) tagging and trunking protocols, which allow for the creation of multiple, isolated LANs on a single physical infrastructure
  • IEEE 802.1p: This standard defines the Quality of Service (QoS) priority tagging, which allows for the prioritization of different types of network traffic.
  • IEEE 802.1X: This standard defines the port-based network access control, which allows for the authentication of devices connected to the network before they are granted access.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configurations on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
