Enterprise-Grade Switching Architecture

High-Density 48-Port Gigabit Ethernet Access Layer

The MS150-48LP-4G provides 48 x 1GbE RJ45 ports, enabling high-density connectivity for endpoints such as IP phones, wireless access points, surveillance cameras, and workstations. This density makes it ideal for enterprise access layer deployment in offices, campuses, and branch environments. Each port supports auto-negotiation and full-duplex communication, ensuring optimized throughput and minimal latency across connected devices.

Optimized for Endpoint Aggregation

The switch is designed to aggregate large numbers of wired endpoints while maintaining consistent network performance. Whether deployed in educational institutions or corporate environments, the 48-port architecture ensures that network congestion is minimized through intelligent traffic handling and Layer 2/Layer 3 segmentation.

Power over Ethernet Plus (PoE+) Capabilities

With integrated PoE+ support across all access ports, the switch delivers both data and electrical power through a single Ethernet cable. This reduces infrastructure complexity and eliminates the need for separate power supplies for connected devices.

370W PoE Budget for High-Demand Devices

The total PoE budget of approximately 370 watts allows simultaneous powering of multiple high-consumption devices such as PTZ IP cameras, Wi-Fi 6 access points, and VoIP phone systems. Intelligent power allocation ensures that critical devices remain powered even under peak load conditions.

Dynamic Power Allocation Efficiency

The switch dynamically distributes power based on device requirements, ensuring energy efficiency while maintaining network stability. Devices negotiate power levels automatically, reducing unnecessary energy consumption.

Uplink and Expansion Capabilities

4 x 1GbE SFP Uplink Ports

The inclusion of 4 SFP uplink ports enhances network scalability by allowing fiber or copper uplink connections to aggregation switches, core switches, or data center networks. These uplinks provide flexibility in network design, enabling both short-range and long-range connectivity options.
