Cisco SG550X-48P-K9-NA Small Business 48 Ports Stackable Refurbished

More Information of this Item

The SG550X-48P-K9-NA is a Cisco Small Business managed switch that supports 48 Gigabit Ethernet ports, with 48 of them being PoE+ (Power over Ethernet Plus) capable. It also supports Layer 3 routing capabilities and has SFP+ (small form-factor pluggable) ports for fiber connectivity. It is designed for small to medium-sized businesses that need a high-performance network switch with advanced features. This switch supports advanced features such as Quality of Service (QoS), VLANs, and security features such as access control lists (ACLs) and VPN support. It can be managed via a web interface or through a command-line interface (CLI) using a console connection or Telnet/SSH.

High-Performance

The Cisco SG550X-48P-K9-NA switch is designed to provide high performance and reliability for small to medium-sized businesses. It supports non-blocking, full-duplex operation on all ports, which allows for maximum throughput and minimal packet loss. With support for Power over Ethernet Plus (PoE+), it can provide up to 30 watts of power per port to power devices such as IP phones, wireless access points, and surveillance cameras, without the need for additional power cables.

In terms of reliability, the switch supports a variety of features to ensure the stability and availability of the network. It supports Link Aggregation Control Protocol (LACP) and Cisco EtherChannel technology, which allows for the bundling of multiple physical links to increase bandwidth and provide redundancy. The switch also supports rapid spanning tree protocol (RSTP) and multiple spanning tree protocol (MSTP) to prevent loops in the network and ensure fast recovery in case of a failure.

Additionally, the model supports advanced Quality of Service (QoS) features, which allow for the prioritization of different types of traffic, such as voice and video, to ensure that critical applications have the bandwidth they need to function properly. The switch also supports advanced security features such as access control lists (ACLs) and virtual private network (VPN) support to help protect the network from unauthorized access and ensure the confidentiality and integrity of data transmitted over the network.

Compliant Standards

The Cisco SG550X-48P-K9-NA switch is compliant with a number of industry standards that ensure its compatibility with other networking equipment and ensure that it meets certain requirements for functionality and performance.

Some of the key compliant standards for the model switch include:

• IEEE 802.3: This standard defines the physical layer and media access control (MAC) specifications for Ethernet, which is the most widely-used local area network (LAN) technology.
• IEEE 802.3u: This standard defines the specifications for Fast Ethernet, which provides a data rate of 100Mbps over twisted pair and fiber-optic cables.
• IEEE 802.3z: This standard defines the specifications for Gigabit Ethernet, which provides a data rate of 1Gbps over twisted pair and fiber-optic cables.
• IEEE 802.3ab: This standard defines the specifications for 1000BASE-T, which provides a data rate of 1Gbps over twisted pair cables.
• IEEE 802.3af: This standard defines the specifications for Power over Ethernet (PoE), which allows devices to receive power over their Ethernet cables.
• IEEE 802.3at: This standard defines the specifications for Power over Ethernet Plus (PoE+), which allows devices to receive higher power levels over their Ethernet cables.
• IEEE 802.3x: This standard defines the specifications for full-duplex and flow control in Ethernet networks.
• IEEE 802.1D: This standard defines the specifications for the Spanning Tree Protocol (STP), which is used to prevent loops in a network and ensure that there is a single active path between two devices.
• IEEE 802.1Q: This standard defines the specifications for Virtual LANs (VLANs), which allow for the creation of multiple logical networks on a single physical network.
• IEEE 802.1p: This standard defines the specifications for Quality of Service (QoS) in LANs, which allows for the prioritization of different types of traffic.
• IEEE 802.1w: This standard defines the specifications for Rapid Spanning Tree Protocol (RSTP), which is an enhancement to the Spanning Tree Protocol (STP) that provides faster recovery in case of a failure.

In addition to these standards, the Cisco this model switch also supports a number of Cisco proprietary features such as Link Aggregation Control Protocol (LACP) and Cisco EtherChannel technology, which allow for the bundling of multiple physical links to increase bandwidth and provide redundancy.
