DES-85-24GE-TX Use Case
Data Center Top-of-Rack Aggregation with 24-Port Gigabit RJ45 and 4-Port SFP Uplinks
In a mid-sized data center, IT deploys the D-Link DES-85-24GE-TX board as a top-of-rack switch to connect 24 high-performance servers via gigabit RJ45 and aggregate traffic over four multiplexed SFP fiber uplinks. This converged solution simplifies cabling, delivers up to 4 Gbps uplink capacity, and ensures sub-2 ms port-to-port latency. Benefit: Scalable, low-latency fabric with 99.999% availability and streamlined expansion to core switches.
Multi-Site Enterprise WAN Edge Connectivity with Redundant Fiber Links
A distributed enterprise installs the DES-85-24GE-TX module in its branch office chassis to serve 24 desktops and VoIP phones over RJ45 ports and to link via four SFP ports to dual MPLS and SD-WAN providers. Multiplexed gigabit optical uplinks deliver path redundancy and traffic prioritization for critical business applications. Benefit: 30% higher branch office throughput, automated failover, and consistent QoS for VoIP, video conferencing, and cloud services.
Industrial Automation Backbone for Deterministic Control Networks
In an automotive assembly plant, engineers use the D-Link DES-85-24GE-TX board to connect 24 PLCs and robotics controllers over shielded RJ45 ports while aggregating control-plane data via four SFP fiber links to the central SCADA system. The multiplexed optical uplinks eliminate EMI risks and guarantee sub-millisecond cycle times for time-sensitive protocols. Benefit: 20% increase in production throughput, ultra-reliable network performance, and simplified maintenance with centralized monitoring.
