Linksys Business LGS552P 48-Port Gigabit PoE+ Managed Switch with 2 SFP Combo Ports + 2 SFP+ Ports
Learn how Linksys Managed Gigabit Switches with PoE+ improve productivity with advanced features like Spanning Tree Protocol and Storm Control. 52-port switch featuring Gigabit speed, enhanced security, PoE+, and advanced traffic management.
- Two combo mini-GBIC (SFP) ports
- Two 10-Gigabit uplink Ethernet SFP+ ports
- Integrated Power Over Ethernet Plus (PoE+)
- Layer 3 static routing
- IPv6 Support
- Advanced QoS
- Meets EEE (Energy Efficient Ethernet) 802.3az standard
Advanced Network Management CapabilitiesAdvanced features include Layer 2 Switching and Layer 3 Static Routing between different VLAN communications without any performance degradation for a more efficient network. Linksys 500 Series Switches manage internal routing with your router and dedicate fixed paths to external traffic and security.
Integrated Power over Ethernet Plus (PoE+)Makes installation simple and inexpensive by eliminating the need for additional power cables and nearby power outlets. Backwards compatible with 802.3af (PoE) standard.
Advanced Traffic-Handling IntelligenceLayer 2 MAC and Layer 3 IP Flow-based Policies and Rate Limiting Control prioritize traffic, offering an ideal solution to manage and control real-time, high bandwidth, voice and video traffic without slowing down your other business applications.
Advanced Network Security FeaturesExtensive Access Control Lists (ACLs) control and block portions of the network from unauthorized users and external network attacks, while DHCP Snooping, IP and MAC-Port Binding functions help ensure network integrity. IEEE 802.1X Port Security strictly limits access to specific segments of your network, and Port Authentication and MAC-based Port Security require clients to authenticate themselves before any data passes.
Fiber-Optic Network Expansion SupportAdditional Gigabit SFP+ Fiber-Optic port expansions provide a powerful combination of business scalability for any server farm and data center environment, and enhance high bandwidth demands while providing redundancy for fast and easy network growth. Mini Gigabit Interface Converter (mini-GIBC) expansion ports offer the option to add fiber-optic or Gigabit Ethernet uplink connectivity to these managed switches.
Optimal Energy-Efficient Ethernet SupportReduce energy consumptions by monitoring the amount of traffic and states of any inactive ports without compromising performance. Linksys 500 Series Switches are specifically designed to optimize power and efficiency and support the Energy-Efficient Ethernet (IEEE 802.3az) Standards.
