## Summary description

The Icy Dock MCIO 4i (MB408A5) is a PCIe adapter designed to provide a PCIe 5.0 x4 host connection with an integrated redriver. It enables connection of U.2 or HHHL NVMe drives to a PCIe slot, improving signal integrity for high-speed NVMe storage. Suitable for workstations and servers requiring reliable NVMe expansion and hot-swap compatible drive integration.

## Long description

The PCIe 5.0 x4 Adapter with Redriver Icy Dock MCIO 4i (MB408A5) is a PCIe expansion card that provides a PCIe 5.0 x4 host interface and an integrated redriver to support high-speed NVMe storage. The adapter accepts U.2 or HHHL NVMe drives and converts their connection to a standard PCIe slot, maintaining signal integrity for demanding workloads. It is intended for installation in desktop workstations or servers where additional NVMe storage or hot-swap capability is required.
Advantages
This adapter integrates a redriver to compensate for signal degradation at PCIe 5.0 speeds, reducing data errors and improving link stability when using long traces or riser setups. It supports both U.2 and HHHL NVMe form factors, providing flexibility in drive choice and deployment. The design allows straightforward installation into a PCIe slot and supports hot-swap capable U.2 drives when used with compatible backplanes or enclosures.
Suitable for
 Expanding NVMe storage capacity in workstations
 Adding NVMe drives to servers without native U.2/HHHL connectors
 Integrating hot-swap U.2 drives with PCIe-based systems
 Environments requiring improved signal integrity for PCIe 5.0 x4 links
Key specifications
 Interface: PCIe 5.0 x4 host connection
 Supported drive types: U.2 and HHHL (NVMe) form factors
 Integrated component: redriver for signal conditioning
 Usage: internal PCIe slot installation for desktop or server systems
How to use
Install the adapter into an available PCIe slot on the motherboard, ensuring the slot provides at least four PCIe lanes. Secure the card to the chassis and connect any necessary power or chassis adapters according to the host system requirements. Mount a compatible U.2 drive or HHHL NVMe card onto the adapter following the drive manufacturer's instructions. Once installed, verify that the host system BIOS/UEFI and operating system detect the NVMe drive and install or update any required drivers.
Usage recommendations
For optimal performance, use the adapter in a full-length PCIe slot that supports PCIe 5.0 or the highest supported generation of your platform. Ensure proper airflow and cooling around NVMe drives to maintain sustained transfer rates. When using hot-swap functionality, confirm compatibility with your backplane or enclosure and follow safe removal procedures to prevent data loss.
