Description

The Linksys LGS328MPC is a 410W TAA-compliant 24-port Managed Gigabit switch that offers a quick and easy solution to extend your office network. It features gigabit speed ports, a web interface for easy configuration and management, and Power over Ethernet (PoE+) support for networking devices to be located anywhere without needing alternating current (AC) outlets.

Product Features

• Power over Ethernet Plus (PoE+):
  Linksys managed switches support the latest 802.3at (PoE+) standards and provide up to double the power budget per Gigabit Ethernet port while offering 802.3af (PoE) backward-compatibility. Power over Ethernet reduces electrical wiring costs, simplifies installation, and supports network devices such as IP cameras and wireless access points in optimal indoor and outdoor locations.
• 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.
• Network Security:
  Unauthorized access to the network and mission-critical data is a constant concern. Linksys managed switches help secure networks through port authentication, requiring clients to authenticate themselves before any data is passed. Advanced DHCP snooping and IP-MAC binding functions ensure network integrity and help prevent network attacks.
• 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 bandwidth-intensive graphic/video file uploads and downloads. IGMP snooping limits IP multicast traffic to the ports that requested it, enabling the rest of the network to operate at peak efficiency.
