Network switch D-Link S4600-28P-SI-R3.5 — L2, 24x RJ45, 4x SFP

D-Link S4600-28P-SI-R3.5 is a Layer 2 network switch with 24 RJ45 ports and 4 SFP slots designed for small-to-medium enterprise deployments. The switch provides wired Ethernet access for workstations, IP phones and servers, with fiber uplink flexibility via SFP modules. It supports standard L2 switching features appropriate for access or aggregation layer roles and is intended to deliver predictable connectivity in office and campus environments.

Advantages

This network switch offers a combination of copper ports and SFP slots that enables mixed-media connectivity without additional converters. Integrated L2 switching functions simplify VLAN segmentation, MAC address learning and basic traffic control, reducing management complexity in multi-device networks. The physical port density supports typical office deployments while fiber-capable uplinks provide longer-distance connections and integration with core switches or fiber distribution.

Suitable for

• Access layer connectivity for offices and branch locations
• Connecting IP phones, desktop computers and small servers
• Aggregation of multiple access switches into a fiber uplink
• Environments requiring a combination of copper and fiber interfaces

Key specifications

• Layer 2 switching capabilities
• 24 RJ45 Ethernet ports for copper connectivity
• 4 SFP slots for fiber or additional uplink modules
• Suitable port density for small-to-medium enterprise access
• Support for VLAN segmentation and MAC-based forwarding

How to use

Install the switch in a standard 19-inch rack or place it on a stable surface and connect power according to site practices. Connect end devices such as PCs and IP phones to the RJ45 ports using appropriate Ethernet cables and insert SFP modules into the SFP slots for fiber uplinks where required. Configure basic Layer 2 settings — VLANs, port modes and MAC learning — through the device management interface according to the network design, and verify connectivity and link status before putting the switch into production.

Usage recommendations

For reliable operation, use quality shielded or unshielded Ethernet cables as appropriate for the installation, choose SFP modules that match the fiber type and distance requirements, and apply VLAN segmentation to separate voice and data traffic. Monitor port utilization and link status through the switch management tools to plan capacity and avoid congestion.
