Product Detail

Description

SH-ME3448 is a commercial-grade managed ethernet switch that provides 4 Gigabit SFP slots and 48* 10/100/1000Base-T ports. It supports ERPS ring network and complies with the G.8032 ERPS Ethernet ring protection switching protocol, with a self-healing time of less than 50ms. In case of network failures, it can quickly recover to ensure uninterrupted communication for critical applications. Additionally, it supports L2+ network management functions, allowing device management and configuration via Web, Telnet, Console (CLI), and SNMP. With superior performance, simple operation, and user-friendly interface, this product offers an ideal networking solution for workgroup users or small local area networks.
