HUAWEI S2750-28TP-PWR-EI-AC – Product Information

Name: HUAWEI S2750-28TP-PWR-EI-AC Switch - SunSpike
SKU: S2750-28TP-PWR-EI-AC

Product Overview

The HUAWEI S2750-28TP-PWR-EI-AC is an enterprise-grade Layer 2 Ethernet switch designed primarily for small to medium-sized office networks and campus access scenarios. Housed in a 1U standard rack-mountable chassis, this switch delivers a switching capacity of 64 Gbps and a forwarding rate of 14.1 Mpps.

The device features 24 × 10/100 Mbps PoE+ ports that can simultaneously supply power to terminal devices such as wireless APs and IP phones, alongside 4 Gigabit uplink ports for flexible network expansion. It supports up to 4K VLANs and maintains a 16K MAC address table.

Built with enhanced reliability in mind, the S2750-28TP-PWR-EI-AC incorporates built-in 7KV surge protection technology to effectively defend against induced lightning overvoltage. It supports 802.1X authentication and MAC address authentication, with dynamic or static binding of user identification elements including IP, MAC, VLAN, and port, as well as dynamic provisioning of user policies (VLAN, ACL).

The switch integrates Huawei’s intelligent stacking iStack technology, which enhances switching capacity, reliability, and scalability—stacked logical systems share a single IP address with unified configuration management, significantly reducing O&M costs. Additionally, Huawei Easy Operation enables simplified installation, configuration, monitoring, and fault handling, substantially lowering initial deployment and configuration expenses.

The device supports a wide operating temperature range of –5°C to 50°C and measures 442 × 310 × 43.6 mm, with a weight of approximately 4.5 kg.
