Product Overview

The Huawei S5700-26X-SI-12S-AC is an enterprise-class Layer 2 Gigabit Ethernet switch designed for small to medium-sized network environments, primarily serving data link layer access and traffic management. The model nomenclature indicates it belongs to the S5700 SI (Standard) series, an enterprise networking product with 26 ports (12 electrical ports + 12 optical ports + 2 uplink 10GE optical ports) powered by AC input.

The switch features a store-and-forward switching architecture with a switching capacity of 256 Gbps and a forwarding performance of 66 Mpps. It is equipped with 26 fixed ports in a non-modular structure: 12 × 10/100/1000BASE-T Ethernet ports, 12 × 100/1000BASE-X SFP ports, and 2 × 10GE SFP+ uplink ports.

The device supports intelligent iStack stacking, comprehensive QoS policies, dual power supply support, Ethernet OAM/BFD detection, built-in AHM energy-saving technology, and Virtual Cable Test (VCT). It offers extensive management capabilities including SNMPv1/v2/v3, RMON, web-based management, Telnet, and HGMP cluster management. Security features include user分级 management, password protection, DOS/ARP attack prevention, MAC/IP/port/VLAN binding, port isolation, IEEE 802.1X authentication, and AAA authentication with RADIUS, HWTACACS, and NAC support.

With compact dimensions of 442 × 310 × 43.6 mm and a weight of 6.6 kg, the switch operates within a temperature range of 0°C to 50°C and humidity range of 5% to 95% (non-condensing).
