PCIe-8372

Description

The National Instruments PCIe-8372 MXI-Express Interface Board, with part number 779724-01, is designed to extend the capabilities of your computer system using a maximum cable length of 7 meters. This board boasts two ports and supports lane widths of x4, which includes four x1 PCI Express lanes, enabling a high transfer rate of 10 Gbps bi-directionally. It requires a PCI Express slot of x4 or higher and adheres to the PCI Express Specification, Revision 1.0a.

This interface board allows for enhanced system scalability, offering the ability to link multiple PXI Express chassis or to daisy-chain with compatible MXI-Express x4 models. However, it is important to note that using a slot larger than x4 may result in the board negotiating down to x1, which could affect performance, and it is not recommended to use this board in slots intended for graphics cards. The board also features a PWR/LINK LED with various statuses: Off indicating power off, Solid Red signaling power is out of specifications, Solid Amber showing power is within specifications but not linked, and Solid Green confirming that power is within specifications and a link has been successfully established.

Question 1: What are the potential performance implications of using the National Instruments PCIe-8372 MXI-Express Interface Board in a PCI Express slot larger than x4, despite its ability to link multiple PXI Express chassis or daisy-chain with other MXI-Express x4 models?
Answer 1: The National Instruments PCIe-8372 MXI-Express Interface Board supports a maximum cable length of 7 meters, and a Solid Green PWR/LINK LED indicates that power is within specifications and a link has been successfully established.

Question 2: What is the maximum supported cable length and bi-directional transfer rate of the National Instruments PCIe-8372 MXI-Express Interface Board with part number 779724-01?
Answer 2: The maximum supported cable length for the National Instruments PCIe-8372 MXI-Express Interface Board with part number 779724-01 is 7 meters, and it supports a bi-directional transfer rate of 10 Gbps.

Question 3: What is the maximum cable length supported by the National Instruments PCIe-8372 MXI-Express Interface Board, and what does a Solid Green PWR/LINK LED indicate about the board’s status?
Answer 3: When the National Instruments PCIe-8372 MXI-Express Interface Board is used in a PCI Express slot larger than x4, it may negotiate down to x1 lane width, which could negatively impact performance. The board’s PWR/LINK LED indicates various statuses: Off means power is off, Solid Red indicates power is out of specifications, Solid Amber shows power is within specifications but not linked, and Solid Green confirms that power is within specifications and a link has been successfully established.

Question 4: What are the implications for performance when the National Instruments PCIe-8372 MXI-Express Interface Board is used in a PCI Express slot larger than x4, and what are the different statuses indicated by the board’s PWR/LINK LED?
Answer 4: The maximum cable length for the National Instruments PCIe-8372 MXI-Express Interface Board, part number 779724-01, is 7 meters, and it supports a high data transfer rate of 10 Gbps bi-directionally; when the PWR/LINK LED displays a solid green light, it indicates that power is within specifications and a link has been successfully established.

Question 5: What are the maximum cable length and the data transfer rate of the National Instruments PCIe-8372 MXI-Express Interface Board, part number 779724-01, and what does the PWR/LINK LED indicate when displaying a solid green light?
Answer 5: Using the National Instruments PCIe-8372 MXI-Express Interface Board in a PCI Express slot larger than x4 could lead to the board negotiating down to x1 lane width, which may decrease the overall performance due to lower data transfer rates compared to the optimal x4 lane configuration.
