Expansion Cards for Rackmount Industrial Servers

Product Specifications

Technical details and manufacturing context for Expansion Cards

Definition

Expansion cards are modular circuit boards designed to be installed into rackmount industrial servers via standardized expansion slots (such as PCIe). They enhance server capabilities by adding specialized functions like additional network interfaces, storage controllers, graphics processing, industrial I/O connectivity, or specialized computing accelerators, allowing customization for specific industrial applications. These cards are typically manufactured on FR-4 PCB material with copper traces and populated with electronic components such as ICs, capacitors, and resistors. They come in a standard full-height, half-length form factor measuring 167.65 x 111.15 mm, and weigh between 100 and 200 grams depending on the model. The interface is PCIe 3.0/4.0, backward compatible, and the cards are designed to fit into a PCIe x16 slot. Power consumption ranges from 25 to 75 watts, sourced from the slot. They are rated for industrial-grade operating temperatures from 0 to 60°C, storage temperatures from -40 to 85°C, and non-condensing humidity from 5% to 95% RH. The mean time between failures (MTBF) is specified as 50,000 hours at 25°C. Compliance with EMC and safety standards is indicated by CE and FCC markings, but these must be verified for the specific model. Expansion cards are selected based on the required function, slot availability, and power budget. Verification questions include checking slot compatibility, power draw, and driver support. Maintenance signals include driver errors, system instability, or failure to recognize the card. Failure boundaries are defined by the card's operating limits; exceeding them may cause malfunction or permanent damage.

Working Principle

Expansion cards connect to the server's motherboard through expansion slots, establishing electrical and data communication pathways. They contain specialized chipsets and circuitry that perform specific functions, with the server's operating system or industrial control software recognizing and utilizing these added capabilities through device drivers. The card's interface (PCIe) provides high-speed data transfer between the card and the CPU, enabling the added functionality to be integrated into the system's operations.
