52-Port Business Managed Gigabit

Switch (LGS552)

Add secure, reliable, powerful switching to your growing business network, with state-of-the-art features and performance including Gigabit speed, enhanced security, and advanced traffic management ideal for real-time voice and video applications.

Quality of Service (QoS)

Numerous QoS features ensure that traffic is prioritized properly to deliver the best possible user experience for real-time applications like voice and video along with bandwidthintensive graphic/video file uploads and downloads. Advanced QoS provides per flow base policer and rate limit to enforce SLA requirement.

Network Security

Unauthorized access to the network and mission-critical data is a constant concern. Linksys Managed Switches offer to secure networks through port authentication and MAC-based port security, requiring clients to authenticate themselves before any data is passed. Advanced DHCP snooping and IP-MAC-Port binding functions ensure network integrity and help prevent network attacks.

Network Expansion

Linksys Managed Switches include features for quickly expanding and growing your network. Multiple high-bandwidth trunks between switches enhance availability and redundancy. Spanning Tree Protocol (STP) and Storm Control features help control planned or inadvertent cable loops, so you can confidently build a mesh of switches and quickly expand your network to support your growing workforce. With additional Gigabit or 10-Gigabit uplink SFP/SFP+ fiber-optic port expansions for servers and data centers, Linksys Managed Switches provide an ideal combination of business scalability and affordability.
