S5720S-28P-LI-AC

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 requiring reliable PoE-enabled edge connectivity.

It provides 24 × 10/100/1000BASE-T PoE+ ports and 4 × GE SFP uplink ports, enabling both end-device connectivity and uplink integration into aggregation or core networks. The PoE capability allows it to power devices such as IP phones, wireless access points, and surveillance cameras directly through Ethernet.

This switch is typically deployed in the access layer of enterprise campus networks, but can also be used in SMB environments where PoE and Gigabit access are required. It supports stacking via GE uplink ports, allowing multiple switches to operate as a single logical unit for simplified management and scalability.

The S5720S-28P-LI-AC supports enterprise Layer 2 and Layer 3 features including:

• VLAN segmentation
• QoS traffic management
• IPv4/IPv6 routing (software dependent)
• ACL-based security policies

From a hardware perspective:

• Built-in AC power supply (non-modular design)
• Integrated fan with left-to-right airflow cooling
• Compact 1U rack-mount form factor
• Standard management interfaces (Console, CLI, SNMP, Web)

The PoE power system is designed to support IEEE 802.3af/at devices, making it suitable for unified access and powered edge deployments.

Overall, the S5720S-28P-LI-AC is optimized for small to medium enterprise networks, campus access layers, and IP surveillance environments requiring PoE plus Gigabit performance.
