## Summary description

D-Link S5750E-28F-SI-D is an L3 Lite network switch designed for aggregation and distribution layers in enterprise or service provider networks. It provides 16 SFP ports for fiber uplinks, 8 combo SFP/metal ports for flexible connectivity and 4 dedicated 10G ports for high-bandwidth links. The switch supports Layer 3 features for routing and network segmentation, making it suitable for data centers, campus backbone and ISP aggregation.

## Long description

D-Link S5750E-28F-SI-D L3 Lite is a fixed-configuration network switch intended for aggregation and distribution layers in enterprise, campus and service provider networks. It offers a mix of fiber and high-speed ports: sixteen SFP fiber ports for uplinks, eight SFP/metal combo ports for flexible access, and four dedicated 10G ports for high-bandwidth links. The device implements Layer 3 Lite routing capabilities and common management features for segmentation, traffic control and scalable interconnection.
Advantages
The switch combines dense fiber connectivity with dedicated 10G interfaces to support aggregation and backbone roles. Layer 3 Lite features allow inter-VLAN routing and basic routing protocols while keeping configuration and resource requirements lower than full routing platforms. Flexible SFP/metal combo ports give deployment options for either fiber or copper, and the mix of port types simplifies network design for data centers, campus backbones and ISP aggregation points.
Suitable for
 Enterprise aggregation and distribution layers
 Campus backbone and building interconnects
 Service provider aggregation and point-of-presence sites
 Data center top-of-rack or middle-of-row aggregation
Key specifications
 Port configuration: 16 SFP fiber ports, 8 SFP/metal combo ports, 4 fixed 10G ports
 Switching architecture: Layer 3 Lite with inter-VLAN routing support
 High-speed uplinks: four 10G ports for aggregation
 Flexible connectivity: combo ports support either SFP modules or metal RJ-45 copper
 Deployment role: aggregation/distribution and backbone
How to use
Install the switch in a standard 19-inch rack and connect fiber or copper transceivers into the appropriate SFP or combo ports. Use the dedicated 10G ports for uplinks to core switches or servers that require higher bandwidth. Configure VLANs and enable Layer 3 Lite routing to segment traffic between access switches and to provide routed paths between subnets. Use the built-in management interface for initial setup, SNMP for monitoring, and configure QoS and access control lists as required for traffic prioritization and security.
Usage recommendations
For stable operation, populate high-bandwidth links (server uplinks or core connections) onto the dedicated 10G ports while using SFP ports for fiber aggregation. Choose SFP transceivers compatible with your fiber type and distance requirements. Apply VLANs and route summarization to simplify route tables and use QoS to ensure critical traffic receives priority across aggregation links.
