Technical Overview

High-density 48-port 10/100Mbps unmanaged rackmount switch. Features energy-efficient green technology, auto-MDI/MDIX, and standard 19-inch steel casing.

Key Features

  • 48 × 10/100Mbps Auto-Negotiation RJ45 ports supporting Auto-MDI/MDIX [2.1.1]
  • IEEE 802.3x flow control for Full Duplex mode and Backpressure for Half Duplex mode to alleviate traffic congestion
  • Store-and-Forward switching architecture supporting an expanded 16K MAC address table depth
  • Dynamic energy-saving technology adjusts transmission signal strength by detecting cable length and active load
  • Fanless, passive cooling design eliminates noise and reduces mechanical failure points
  • Standard 19-inch steel case design suitable for professional server cabinet or rack-mount installation

100-240V AC, 50/60Hz, typical maximum power consumption under 10W with active energy-saving regulation

Industrial Applications

1. Industrial Office & Control Room Network Consolidation

Consolidates and links numerous desk terminals, SCADA reporting PCs, and legacy office nodes in production facilities directly to the main rack without configuration overhead.

Problem Solved

Avoids the unnecessary cost and security configuration complexities of Layer 3 managed switches when only basic 10/100Mbps connectivity is needed across high-density nodes.

2. Silent IP Surveillance Backbone Expansion

Acts as a central floor distribution switch connecting up to 48 standard definition or mid-resolution IP security cameras in cleanrooms, administrative floors, or storage depots.

Problem Solved

Eliminates fan noise and prevents dust ingress failure points in quiet or dust-sensitive environments through its completely passive, fanless design.

3. Assembly Line HMI and PLC Communication Aggregation

Consolidates local control communication among dozens of PLCs, smart HMIs, and edge IO modules on a localized production line before feeding the uplink to the industrial server.

Problem Solved

Handles dense traffic streams using IEEE 802.3x flow control and a 16K MAC table, eliminating packet drops or buffer errors from mixed automation devices.
