Huawei S5700-28X-LI-DC Switch – Product Information

Name: Huawei S5700-28X-LI-DC Switch - SunSpike
SKU: S5700-28X-LI-DC

Product Overview

The Huawei S5700-28X-LI-DC is a high-performance, enterprise-grade Layer 2 Gigabit Ethernet switch from the S5700-LI series. Designed for中型 to large enterprise networks, data centers, and service provider environments, this switch delivers robust network connectivity with 24 Gigabit Ethernet ports and 4 10-Gigabit SFP+ uplink ports for superior bandwidth and scalability.

The switch features a compact, non-modular chassis design that maximizes port density while minimizing rack space consumption. It is powered by a DC power supply rated at -48 V DC to -60 V DC, making it particularly suitable for telecom environments and centralized power distribution systems. The device supports store-and-forward switching and offers advanced Layer 2 switching capabilities.

Key capabilities include comprehensive VLAN support (up to 4K VLANs), robust Quality of Service (QoS) features with multiple queue scheduling algorithms, and extensive security protocols including AAA authentication, 802.1X, SSH V2.0, and CPU protection. The switch also supports advanced network management features such as SNMPv1/v2/v3, web-based management, automatic configuration, HTTPS, and system logging. Energy efficiency is enhanced with support for IEEE 802.3az Energy-Efficient Ethernet (EEE).

With its combination of high port density, 10GE uplink capabilities, DC power input, and comprehensive feature set, the S5700-28X-LI-DC is an ideal solution for mission-critical network environments requiring high-speed connectivity, redundancy, and future-proof performance.
