A reliable service board suited for enterprise switching environments.
The D-Link DES-85-24GE-SFP is a managed Layer 2 switch featuring 24 gigabit SFP fiber uplinks and a 4-port gigabit RJ45 multiplexing service board, designed for high-density, low-latency enterprise networks.
The DES-85-24GE-SFP offers 24 SFP ports for optical connectivity and a detachable 4-port gigabit RJ45 board for electrical service, enabling flexible fiber-to-copper deployment.
The switch delivers up to 96 Gbps switching capacity with non-blocking architecture, ensuring full-duplex performance on all 28 ports simultaneously.
Yes. The DES-85-24GE-SFP supports 4,096 VLANs, 802.1Q trunking, GVRP, and private VLANs for robust traffic segmentation and security.
Management is provided via web GUI, CLI over SSH/Telnet, SNMP v1/v2c/v3, RMON, and D-Link Network Assistant for centralized monitoring.
Yes. It supports up to 8 Link Aggregation Groups (LAGs) with 8 ports per group, compliant with IEEE 802.3ad for increased bandwidth and redundancy.
The switch offers 8 hardware queues, 802.1p priority, DiffServ (DSCP), Weighted Round Robin (WRR), and strict priority scheduling for traffic shaping.
Absolutely. With 24 SFP uplinks and optional RJ45 ports, it suits aggregation in server farms, campus cores, or fiber-to-the-desktop applications.
The DES-85-24GE-SFP is compatible with standard gigabit SFP modules (SX, LX, LH, BX) from D-Link or any MSA-compliant vendor for diverse link distances.
Power down the switch, remove the blank panel, align the RJ45 board with the guide rails, slide it fully into the slot, and secure with mounting screws.
Maximum power consumption is 45 W under full load; typical idle consumption is around 20 W, making it energy-efficient in 1U rack deployments.
