Huawei S5720S-28P-LI-AC Gigabit PoE Access Switch

Description

The Huawei S5720S-28P-LI-AC is a fixed-configuration Gigabit Ethernet access switch from the Huawei S5720S-LI series, designed for enterprise campus networks and SMB access-layer deployments requiring PoE-powered connectivity.

It provides 24 × 10/100/1000BASE-T PoE+ ports and 4 × GE SFP uplink ports, enabling connection of end devices such as IP phones, wireless access points, and IP cameras, while maintaining uplink flexibility to aggregation or core switches.

This model is primarily used in the access layer of enterprise campus networks, where it delivers both data connectivity and power over Ethernet for edge devices. It supports stacking via Ethernet/SFP uplink ports, allowing multiple switches to be managed as a single logical unit for scalability and simplified operations.

The switch supports standard enterprise switching capabilities including:

• VLAN segmentation
• QoS traffic prioritization
• IPv4/IPv6 routing (feature-dependent on software version)
• ACL-based security control

From a hardware perspective:

• Built-in AC power supply (non-modular design)
• Fanless design with natural heat dissipation, ensuring silent operation in office environments
• Standard management interfaces including Console, CLI, SNMP, and Web management

The integrated PoE capability allows it to deliver power to connected devices directly over Ethernet, reducing the need for separate power supplies and simplifying installation in distributed access networks.

Overall, the S5720S-28P-LI-AC is suitable for enterprise campuses, education networks, government deployments, and SMB environments requiring reliable PoE access switching with Gigabit performance.
