In this video, we will walk you through the setup process for the OSS 4U Pro Gen5 PCIe System. We utilize the OSS Short Depth Server (SDS) as the host for the purposes of this video, but the OSS 4U Pro can be connected to any server with an open x16 PCIe slot.
The 4U Pro is a rugged AI Transportable system that provides optimized, configurable PCIe Gen5 expansion for edge AI applications. As shown in the video, the 4U Pro can support many different PCIe add-in cards, including double-wide GPUs (up to 8). Auxiliary power is provided by the system for add-in cards that require additional power. The 4U Pro can also be configured to provide 16 single-width PCIe Gen4 x8 slots for scale out IO applications, such FPGA data ingest or the latest NVMe storage add-in cards.
One of the most important parts of setup is ensuring that the upstream and downstream cards are properly installed. The upstream card will need to be installed in the host server in an available PCIe x16 slot. The downstream card will come pre-installed in the 4U Pro. This video shows the dipswitch settings for the two cards to confirm they are set properly, and the host can recognize the add-in cards installed in the 4U Pro. These settings can also seen in more detail in the 4U Pro user manual.
Additional features of the 4U Pro Gen5 PCIe Expansion System include the OSS Unified Baseboard Management Controller (U-BMC), replaceable fan filters, and an optional SmartNIC host configuration.

The rugged edge computing landscape is becoming increasingly complex with new generations of technologies, such as the latest AI focused GPUs, releasing annually rather than every 2-3 years. Whether the end application is commercial or defense, rugged edge servers must not only deliver cutting-edge compute performance but also withstand extreme environmental conditions.
When the PCI-SIG formally added support for 675W add-in card devices in the PCI Express Card Electromechanical (CEM) specification in August 2023, NVIDIA’s most powerful CEM GPU, the NVIDIA H100 80GB had a maximum power consumption of 350W. While some devices were starting to push the limits of datacenter thermodynamics – high density systems of many 675W devices seemed like a distant reality. However, with power constraints uncapped and the need for higher performing GPUs skyrocketing, the industry quickly came out with devices taking full advantage of the new specification capability. NVIDIA quickly replaced the H100 80GB with the H100 NVL, increasing power density to 400W. While this small jump was manageable for existing installations, NVIDIA then dove all-in with the H200 NVL released in late 2024 at 600W. The rapid transition from 350W to 600W has put power and cooling technologies in the spotlight in a race to solve this next generation challenge.
