88885363 Inter-Tech Riser Card

High-Performance 1U Passive PCIe Expansion Riser for Low-Profile I/O with the 88885363

The 88885363 is a 1U passive PCIe riser card designed to re-orient a full x16 lane host interface into a left-hand slot position (LHS) low-profile expansion connector, enabling PCIe I/O in chassis where vertical card installation is not possible. By preserving a direct electrical path without retimers or switches, the 88885363 supports predictable PCIe link behavior and minimizes added latency, which is critical for high-throughput network and storage adapters.

Architecturally, the 88885363 provides a PCIe x16 edge connector to the motherboard and exposes a PCIe x16 mechanical low-profile slot for add-in cards, aligning expansion with 1U airflow zones and service clearances. This approach is suited to modern server platforms where CPU-attached PCIe lanes are allocated to NICs, HBAs, or RAID controllers, and where maintaining signal integrity relies on compatible chassis routing and validated board-to-board spacing. Storage and memory remain host-system dependent; the riser’s role is to enable lane access for I/O scaling in dense compute and virtualization nodes.

Why Choose the 88885363?

The 88885363 is selected when a deployment requires deterministic, chassis-integrated PCIe expansion with minimal additional failure domains. Its density-to-performance value comes from enabling a low-profile adapter in 1U without consuming additional rack space, while keeping the PCIe lane map transparent for enterprise configuration, monitoring, and troubleshooting. The 88885363 also supports repeatable builds across compatible chassis, simplifying lifecycle management and sparing strategy.

Inter-Tech focuses on pragmatic server accessory engineering that aligns with data centre serviceability and integration standards, delivering reliable mechanical fitment and consistent connector quality for stable operation in continuous-duty environments.
