Description
The NI PCIe-8381 is a high-performance PXI Remote Controller with part number 782361-01. It falls under the category of PXI Remote Controllers and is designed to offer an efficient x8 Gen2 MXI-Express for PXI Express Interface. This model is specifically engineered to enhance the integration and performance of PXI systems.
One notable feature of the NI PCIe-8381 is its Power Control Feature, which allows for the on/off control of the frame depending on the host framework’s power state. However, this can be manually overridden by powering on the downstream chassis before the host framework, ensuring flexibility in different operation scenarios.
The device also comes equipped with 6 LED Indicators located on the back panel. These indicators provide immediate feedback on the connection status of PCI Express paths, which is essential for troubleshooting and ensuring optimal performance. The LEDs cover various aspects, including the backplane, link port, and SMBus controller link status.
Specifically, the SMBus Controller Link Status LED is a critical indicator that shows whether the PCIe switch has successfully connected to the onboard PCIe-to-PCI bridge for the SMBus controller. It is designed to flicker green with a 25% duty cycle during normal operations, providing a quick visual confirmation of the system’s health.
Moreover, the Backplane Link Status LEDs offer insights into the status of the PCIe links between the NI PCIe-8381 and the PCIe switches on the chassis backplane. This feature is particularly useful for determining the width of the PCIe connections, ensuring that the system is configured for optimal performance.
