Description

Product Description

The Cisco Catalyst 3750G 48-Port PoE Switch is a high-performance enterprise-class managed switch designed for advanced networking environments. Equipped with 48 × Gigabit Ethernet PoE ports and 4 × SFP uplink ports, it provides scalable connectivity for large networks.

Built with Layer 3 switching capabilities, the 3750G supports routing, VLANs, QoS, and advanced security features, making it suitable for enterprise LAN deployments, campus networks, and critical infrastructure.

The switch supports IEEE 802.3af PoE, enabling power delivery to devices such as IP phones, wireless access points, and IP cameras without additional power supplies. It offers a total PoE budget of up to ~370W, allowing flexible power distribution across ports.

Cisco’s StackWise technology allows multiple switches to be stacked and managed as a single unit, improving scalability and redundancy. With robust build quality and proven reliability, this model remains popular in refurbished and used markets.

⚠️ Note: This is an End-of-Life (EoL) product and typically available as used/refurbished.
