The 4UV supports 2 PCIe 3.0 x16 host connections to 16 PCIe 3.0 x8 slots with two 1m cables to the host server. The system supports 16 full length PCIe add-in cards (AICs) such as NVMe flash and industrial I/O. Two fan choices allow for high-power add-in card cooling up to 100W per AIC or a set-and-forget manual speed control using PWM fans when lower power AICs and quiet operation are required. Two 2000W power supplies provide redundant hot-swap system power.
