Cisco SG355-10P-K9 10 Ports Managed Switch Layer3 Refurbished

One such notable offering is the Cisco SG355-10P-K9 Small Business SG355-10, a Layer 3 Managed Switch designed to meet the diverse needs of small businesses. The Cisco SG355-10P-K9 is a member of the Small Business SG355-10 series, known for its scalability, reliability, and advanced management capabilities. This particular model stands out with its Layer 3 Managed Switch functionality, making it suitable for businesses that require efficient routing capabilities within their network infrastructure.

The SG355-10P-K9 boasts 10 ports in total, featuring 8 Power Over Ethernet Plus (PoE+) Ethernet ports. These PoE+ ports enable the switch to deliver both data and electrical power to connected devices, simplifying cable management and reducing the need for additional power sources. Additionally, there are 2 Combo Gigabit ports for versatile connectivity options.

The rack-mountable design of the SG355-10P-K9 is a crucial feature for businesses where space optimization is essential. Here's why this design is noteworthy:

Rack-mounted switches allow for vertical stacking of equipment, optimizing the use of limited space in server rooms or network closets. This is especially advantageous for small businesses with constrained physical footprints.

Rack-mounted switches contribute to a more organized and accessible network setup. Cables can be neatly organized, reducing the risk of accidental disconnections and easing processes.

As businesses grow, the demand for network infrastructure increases. The rack-mountable design of the SG355-10P-K9 facilitates easy scalability, allowing additional switches and equipment to be added to the rack as needed.

The SG355-10P-K9 goes beyond traditional Ethernet connectivity by offering 2 Shared Small Form-factor Pluggable (SFP) ports. Here's why these ports are valuable:

SFP ports support the use of fiber optic cables, which offer several advantages over traditional copper cables. Fiber optic connections provide higher bandwidth, longer reach, and better resistance to electromagnetic interference.

The inclusion of SFP ports adds a layer of versatility to the switch, allowing businesses to tailor their network infrastructure to specific needs. Whether it's connecting buildings across a campus or establishing high-speed links between switches, SFP ports offer flexibility in network design.

Fiber optic connections are known for their reliability and consistent performance. By incorporating SFP ports, the SG355-10P-K9 enhances the overall reliability of the network, especially in demanding or mission-critical applications.

The Cisco Small Business SG355-10P 10-Ports Manageable Layer 3 Switch SG355-10P-K9 is a Layer 3 switch that supports various routing and switching protocols. These protocols allow the switch to perform advanced network functions, such as routing between VLANs, managing Quality of Service (QoS), and providing redundancy.

• Internet Protocol (IP) Routing: The switch supports both static and dynamic IP routing, which allows it to determine the best path for data to travel through the network. The switch supports Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) for dynamic routing between VLANs.
• Virtual LAN (VLAN) Support: The switch supports up to 256 VLANs, which allow for the segmentation of the network into smaller, more manageable sections. This feature allows for greater security and control over network traffic.
• Quality of Service (QoS): The switch supports advanced QoS features, such as traffic prioritization and bandwidth management. These features ensure that critical network traffic, such as voice and video, is given priority over less important traffic, such as file transfers.
• Link Aggregation Control Protocol (LACP): The switch supports LACP, which allows multiple physical links to be combined into a single logical link. This provides increased bandwidth and redundancy, as well as failover protection in case of a link failure.
• Dynamic Host Configuration Protocol (DHCP) Server: The switch includes a built-in DHCP server, which can be used to automatically assign IP addresses to devices on the network. This simplifies IP address management and reduces the chance of IP address conflicts.
• Network Time Protocol (NTP): The switch supports NTP, which allows for synchronization of the switch's internal clock with an external time source. This ensures accurate timekeeping on the switch and across the network.

These protocols can be enabled or disabled through the switch's web-based management interface. This gives network administrators the flexibility to configure the switch to meet the specific needs of their network.

The Cisco Small Business SG355-10P 10-Ports Manageable Layer 3 Switch SG355-10P-K9 also provides various Network Management and Security features.

• Web-based Management Interface: The switch includes a web-based management interface that allows network administrators to configure, monitor, and switch remotely. This interface provides a user-friendly and intuitive interface for managing the switch.
• SNMP Support: The switch supports Simple Network Management Protocol (SNMP), which allows for remote management and monitoring of the switch using SNMP-compatible network management systems.
• Access Control Lists (ACLs): The switch supports ACLs, which allow network administrators to set rules for controlling access to the network. This feature can be used to restrict access to specific IP addresses, ports, and protocols, providing an additional layer of security to the network.
• SSH/SSL Support: The switch supports Secure Shell (SSH) and Secure Sockets Layer (SSL) protocols, which allow for secure remote management of the switch. This provides an additional layer of security, as all communications between the switch and a remote management system are encrypted.
• Port Security: The switch supports port security, which allows network administrators to set a maximum number of MAC addresses per port, and also to configure the switch to take specific actions when the maximum number of MAC addresses is exceeded.
• IEEE 802.1X: The switch supports IEEE 802.1X, which is a network access control standard that requires devices connecting to the network to provide credentials before gaining access. This feature can be used to restrict access to the network to only authorized devices.
• Denial-of-service (DoS) Protection: The switch protects against various types of DoS attacks, such as IP spoofing, IP-directed broadcast, and TCP-SYN flood attacks.

The Cisco Small Business SG355-10P 10-Ports Manageable Layer 3 Switch SG355-10P-K9 supports Power over Ethernet (PoE+) technology, which allows the switch to deliver power and data to devices over Ethernet cables. This eliminates the need for separate power cables for devices such as IP phones, wireless access points, and security cameras.

• PoE+ Power Budget: The switch has a PoE+ power budget of 370W, which means it can supply up to 370 watts of power to PoE-enabled devices connected to the switch. This allows for the connection of multiple PoE-enabled devices to the switch.
• PoE Port Configuration: The switch has 10 Gigabit Ethernet ports, out of which 8 ports are PoE+ capable, which allows you to power PoE-enabled devices such as IP phones, wireless access points, and security cameras through the Ethernet cables. This eliminates the need for separate power cables and simplifies installation.
• PoE Power Allocation: The switch allows you to set the maximum power allocation for each PoE+ port, which means you can configure the switch to allocate different levels of power to different devices depending on their power requirements. This ensures that devices receive the power they need, without overloading the switch.
• PoE Power Management: The switch supports advanced PoE power management features, such as power monitoring and power fault detection, which allows network administrators to monitor the power consumption of PoE-enabled devices and any power-related issues.
• PoE Scheduling: The switch supports PoE scheduling, which allows you to configure the switch to turn PoE on or off on specific ports at specific times. This feature can be used to conserve power and reduce energy costs.
