Huawei S5700 Series Switches S5720S-28X-SI-DC Overview
Huawei S5700 Series Switches S5720S-28X-SI-DC is a genuine campus and data-center switching product from Huawei, a worldwide ICT vendor with a strong portfolio of enterprise switches, routers and data-center hardware. Belonging to the Huawei S5700 Series family, the S5720S-28X-SI-DC unit is built to the original factory specification, so it integrates with existing Huawei deployments predictably and behaves exactly as the platform documentation describes. In the network, it is suited to access-layer and edge deployments, where reliable wiring-closet operation and straightforward management are the priorities.
From a specification standpoint, it offers 24 ports for client, server or uplink connectivity; packet forwarding up to 78 Mpps. These are the original factory figures for this model, giving administrators a clear picture of what the unit can deliver before it enters service. Standard mounting, cabling and management practices apply, so deployment follows the same procedures as other Huawei hardware already running in the environment.
Typical deployments include access-layer deployments for user, phone and AP connectivity, distribution and core aggregation in campus networks, and top-of-rack and end-of-row switching in data centers. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “S5720S-28X-SI-DC (24 Ethernet 10/100/1000 ports,4 10 Gig SFP+,DC -48V)”. This makes it a practical choice when original-spec hardware is required at a predictable cost.

S5720S-28X-SI-DC - Huawei Series Notes
This listing is part of the Huawei enterprise networking product family, sourced and tested by LinkNewNet for enterprise deployment. Huawei switch is typically deployed in campus access, aggregation, or data-center roles. It provides reliable Layer 2/3 switching for user, server and uplink connectivity, and integrates with Huawei iMaster NCE or traditional CLI-based management.
Deployment guidance: When planning this S5720S-28X-SI-DC unit into a network, confirm the software image (VRP / iMaster NCE), the power and cooling profile, and the upstream/downstream interface types that match your existing infrastructure. For a like-for-like refresh, match the feature set of the units already in service so management and automation behave consistently.
Our Huawei reconditioning process: Every pre-owned Huawei unit at LinkNewNet passes a documented reconditioning flow before dispatch - visual inspection, internal cleaning, firmware verification, port-by-port testing, and configuration reset to factory defaults. This ensures the unit you receive operates reliably and integrates cleanly with your existing Huawei management tools.
