Cisco Catalyst 3750 48-port switch WS-C3750-48TS-E-RFB Layer 3

The Cisco Catalyst 3750 48 Port Switch WS-C3750-48TS-E-RFB Layer 3 is an enterprise-class network switch providing 48 Ethernet ports with Layer 3 capabilities and advanced security. Designed for campus and branch deployments, this Cisco Catalyst 3750 series unit supports comprehensive switching features and Power over Ethernet (PoE) support for connected devices. The WS-C3750-48TS-E-RFB enables efficient traffic management, segmentation, and connectivity for voice, data and wireless access points in medium to large networks.

Advantages

The switch combines Layer 3 routing features with a high-density 48-port configuration to simplify network design and reduce the need for additional routing devices. Built-in security features protect network access and can integrate with existing enterprise security policies. Power over Ethernet capability supports deployment of IP phones, wireless access points and other powered devices without separate power supplies. The device is compatible with standard management tools used for Cisco enterprise switches.

Suitable for

• Campus access layer deployments requiring high port density
• Branch office networks with mixed voice and data traffic
• Environments that require PoE for IP phones and wireless access points
• Networks needing Layer 3 features for routing between VLANs

If using PoE, verify power budget and connect powered devices such as IP phones or wireless access points to the ports designated for PoE.

Recommendations

For stable operation, use the switch in temperature-controlled environments and follow Cisco maintenance guidelines. Regularly back up configuration files and apply firmware updates from Cisco to maintain security and feature compatibility. Monitor power consumption if many PoE devices are connected to ensure the switch power budget is not exceeded.
