How to install One Stop Systems 4U Value 16-Slot Expansion System

• Plan and prepare: Verify your server supports two PCIe 3.0 x16 host connections and has available PCIe slots to connect the expansion chassis. Ensure you have two 1-meter PCIe cables included or specified for the setup.
• Rack placement and power: Slide the 4U chassis into a compatible rack, secure it, and connect the power supply according to your data center's power architecture. Confirm proper airflow around the enclosure ensuring adequate cooling for densely populated PCIe cards.
• Connect the host cables: Attach the two PCIe 3.0 x16 host cables from the expansion chassis to the corresponding PCIe x16 slots or connectors on the host server. Confirm a firm, secure connection to minimize signal integrity issues.
• Install PCIe add-in cards: One by one, insert up to 16 full-length PCIe cards into the 16 x8 expansion slots. Follow card orientation guidelines and ensure that each card is seated completely and secured with the appropriate brackets or screws to prevent movement during operation.
• Power up and verify: Restore power and boot the server. In the operating system, verify that all installed PCIe cards are recognized. Install or update drivers as needed and run initial tests to confirm that bandwidth and slot assignment meet your workload requirements.
