The part number **38-R144F1000** typically refers to a specialized component often found in high-performance computing (HPC), server infrastructure, or networking hardware. Based on industry standards, this identifier is frequently associated with **PCIe Riser Cards** or **Server Expansion Modules**. --- ### Technical Specifications & Overview This component is designed to facilitate the connection between a motherboard and peripheral expansion cards (such as GPUs, NICs, or RAID controllers) in space-constrained environments like 1U or 2U rackmount servers. | Feature | Specification | | :--- | :--- | | **Component Type** | PCIe Riser Card / Expansion Board | | **Interface** | PCIe x16 (typically Gen 3 or Gen 4) | | **Form Factor** | Low-profile / Proprietary Rackmount | | **Typical Application** | Server GPU expansion / Storage controllers | | **Compatibility** | Specialized Server Chassis (e.g., Gigabyte, Tyan, or Supermicro) | --- ### Key Functions 1. **Signal Routing:** It reroutes the high-speed PCIe lanes from the motherboard's horizontal slot to a vertical or offset position, allowing full-sized cards to fit in slim chassis. 2. **Power Delivery:** These boards often include additional power circuitry to ensure that high-draw components (like high-end networking cards) receive stable 12V and 3.3V rails. 3. **Signal Integrity:** High-quality capacitors and traces on the PCB ensure that data transmission remains stable across the extended physical distance. ### Installation Context In a typical server setup, the **38-R144F1000** would be installed as follows: * **Bottom Connection:** Plugs into the "Riser" slot on the server motherboard. * **Top/Side Connection:** Provides one or more PCIe slots for the actual peripheral card. * **Retention:** Usually secured via a metal bracket specific to the server's internal cage. --- ### Troubleshooting & Maintenance If you are dealing with a faulty unit, check the following: * **Physical Alignment:** Ensure the gold fingers are clean and fully seated in the motherboard slot. * **PCIe Training Errors:** If the connected card is not recognized, check if the BIOS/UEFI requires a specific PCIe bifurcation setting (e.g., splitting x16 into x8/x8). * **Thermal Management:** Ensure the riser isn't blocking critical airflow to the CPU or the card it is supporting.
