Huawei eKit S310-48P4S — Enterprise PoE+ Gigabit Switch for SMB and Business Networks

Huawei S310-48P4S is a 48-port Gigabit PoE+ switch with SFP uplinks, designed for access layer deployments in medium and large enterprises with high device density. It is used in infrastructures where IP cameras, wireless access points, and VoIP phones must be powered and managed from a single device, with traffic aggregated toward the core through SFP slots. The 380W PoE budget supports simultaneous powering of a large number of endpoints without additional external power supplies.

The switch operates at a typical power consumption of 48.64W rising to 462.8W under full PoE load, with cooling handled by two intelligent fans with automatic speed adjustment. With 2 GB RAM and 1 GB Flash supporting advanced L2/L3 switching functions, surge protection at ±7 kV on service ports ensures resilience in environments with voltage fluctuations. The metal chassis and 227 mm depth ensure compatibility with standard 1U racks.

The S310-48P4S supports VLAN, QoS, ACL, and SNMP, covering the security, segmentation, and monitoring requirements of high-density enterprise networks. It integrates into centrally managed Huawei infrastructures and accepts both AC and high-voltage DC input (190–290V DC), useful in environments with DC UPS or industrial power sources. The RJ45 console port enables local configuration without network access.

Recommended for multi-floor office buildings, campuses, hotels, and video surveillance infrastructures with high PoE device density. Compared to the S310-48P4X with 10G uplinks, the 4S variant with Gigabit SFP slots is suited for networks where standard uplink aggregation capacity is sufficient.
