It ensures reliable performance and seamless integration with the server's internal architecture.

## Long description

The HPE ProLiant DL3X5 Gen11 1U x16 Riser Kit is a specialized hardware expansion component engineered specifically for the HPE ProLiant DL3X5 Gen11 server series. This riser card allows for the integration of high-performance PCIe x16 expansion cards into a compact 1U rack-mount chassis, effectively increasing the server's hardware capabilities. By providing a stable and reliable connection point, this kit ensures that additional networking, storage, or accelerator cards function seamlessly within the server's internal architecture, maintaining optimal system performance for demanding enterprise workloads.
Advantages
This riser kit offers a significant advantage by maximizing the utility of the limited space available in 1U server environments. It provides a robust and secure physical interface for PCIe x16 cards, ensuring that high-bandwidth components are properly supported and cooled within the chassis. The design is optimized for the specific thermal and electrical requirements of the Gen11 architecture, which minimizes the risk of compatibility issues and ensures long-term operational reliability for critical server infrastructure.
Suitable for
Expanding network connectivity with additional high-speed NICs
Adding specialized storage controllers for increased data throughput
Integrating hardware accelerators for compute-intensive tasks
Upgrading server hardware configurations for enterprise-grade applications
When it may not be suitable
This riser kit is exclusively designed for the HPE ProLiant DL3X5 Gen11 server series and will not fit or function in other server models or different chassis form factors. It is also not intended for use in systems that do not require PCIe x16 expansion or where the internal space is already fully occupied by other critical components.

How to use
To install the riser kit, first ensure the server is powered down and disconnected from all power sources. Open the server chassis according to the manufacturer's service manual and locate the designated riser slot on the system board. Carefully align the riser card with the slot and press down firmly until it is fully seated. Once the riser is installed, you can insert your PCIe x16 expansion card into the riser's slot, ensuring it is properly secured. Close the chassis, reconnect the power, and verify that the new hardware is detected by the server's BIOS or operating system.
What to consider before purchase
Verify that your specific server model is part of the DL3X5 Gen11 series
Check the available internal space within your 1U chassis
Ensure the PCIe card you intend to install is compatible with the x16 interface
Confirm that your power supply unit can handle the additional load of the new expansion card
Usage recommendations
Always perform hardware installations in a static-safe environment to prevent damage to sensitive electronic components. Ensure that the server firmware is updated to the latest version before installing new expansion hardware to guarantee full compatibility and optimal performance.
