In a global financial services data center, the DES-8503 final assembly chassis (including 1 fan tray, 2 power supply slots, standard configuration without power supply, 1 main control slot, 2 business slots) is deployed as the core aggregation switch. The 1 main control slot hosts a high-performance control module, while dual business slots carry 40 GbE line cards. Redundant PSUs and the dedicated fan tray ensure N+1 power and cooling resilience. Outcome: sub-50 μs latency, >99.999% uptime and seamless fail-over, meeting stringent SLAs for trading and risk systems.
A large university implements the DES-8503 final assembly chassis (including 1 fan tray, 2 power supply slots, standard configuration without power supply, 1 main control slot, 2 business slots) at each campus building distribution point. The modular chassis allows hot-swap power supplies and field-installable fan trays for on-demand upgrades. The 1 main control slot runs advanced routing protocols (VRRP, MSTP), while 2 business slots support 24×1 GbE and 4×10 GbE uplink modules. Outcome: flexible port scaling, centralized QoS, and simplified segmentation, delivering high-speed access for 30,000+ students and IoT devices.
An automotive assembly plant uses the DES-8503 final assembly chassis (including 1 fan tray, 2 power supply slots, standard configuration without power supply, 1 main control slot, 2 business slots) to build its mission-critical OT network backbone. The industrial-grade fan tray and redundant power supply slots (populated with diverse PSUs) maintain continuous operation in harsh environments. The main control slot runs deterministic L2/L3 switching, while business slots host TSN/QoS line cards for real-time control of PLCs and robotics. Outcome: zero unplanned downtime, deterministic latency below 2 ms, and 15% productivity uplift under Industry 4.0 standards.

The DES-8503 chassis supports two redundant and load-sharing AC or DC power supplies to ensure uninterrupted operation.
No, the DES-8503 is shipped without power supplies; compatible D-Link power modules must be ordered separately.
The chassis is compatible with D-Link DPS-300AC and DPS-300DC power supplies, supporting redundant AC or DC operation with hot-swap capability.
The DES-8503 provides one main control module slot and two business module slots, allowing flexible expansion of switching ports and services.
The chassis includes a front-to-back hot-swappable fan tray with temperature-controlled fans for efficient airflow and minimal noise.
The DES-8503 measures 440 × 420 × 44 mm (W×D×H) and weighs approximately 8 kg without modules or power supplies.
Yes, the DES-8503 is a 1U rack-mountable chassis that fits standard 19-inch data center and telecom racks with included mounting brackets.
The chassis operates reliably in 0 °C to 45 °C ambient temperature and 10 % to 90 % non-condensing relative humidity.
Business slots accept D-Link line cards offering 1 GbE, 10 GbE, PoE/PoE+ and specialized security or aggregation modules.
Power down the chassis, slide modules or PSUs into their respective slots until they click, secure with captive screws, and then restore power; fans remain hot-swappable.
The chassis supports SNMPv2/v3, CLI via console/SSH, and an embedded web GUI through the main control module for centralized management.
The chassis itself consumes under 30 W without power supplies; total power draw depends on installed PSUs and active line cards.
