Description
CISCO SG350-28P-K9-EU - Cisco SG350-28P 28-port Gigabit POE Managed Switch
Designed for robust network management, this Cisco switch is an optimal choice for IT departments and system integrators seeking to enhance operational efficiency and maintain secure, high-performing networks. Offering 28 Gigabit Ethernet ports with Power over Ethernet (PoE) capabilities, it ensures seamless connectivity and power distribution to a wide range of network devices such as IP phones and wireless access points. The device supports a total PoE budget of 195 watts, accommodating the power needs of various installations without the need for additional electrical infrastructure.
The switch is equipped with advanced Layer 3 capabilities, including support for 512 static routes and 128 IP interfaces, which allow for sophisticated network segmentation and traffic management. With a switching capacity of 56 Gbps and a forwarding rate of 41.66 Mpps, it provides the throughput necessary for growing data demands while maintaining network reliability. Its compatibility with networking standards such as IEEE 802.1x and 802.3at ensures interoperability across diverse network environments, facilitating easy integration into existing infrastructures.
Security and management are streamlined with features like Access Control Lists (ACLs) and Quality of Service (QoS) support, enabling precise control over data flow and prioritization of critical traffic. It also includes web-based management and SNMP support, simplifying monitoring and configuration processes. The device's robust design, certified by UL, CSA, CE, and FCC, guarantees durability, while its efficient heat dissipation and low power consumption of 35.7 watts contribute to cost-effective and sustainable operation. With a mean time between failures (MTBF) of nearly 397,000 hours, this Cisco switch stands as a reliable addition to any enterprise network.
