Installation and Configuration
Notes
If the system fan fails the chassis will shut down automatically, preventing
the chassis and modules from damage due to overheating. The chassis will not
attempt another power on until AC power has been cycled.
If the power supply has a failure, the chassis will prevent potential damage by
shutting down automatically. The chassis will not attempt another power on until AC

Functional Overview
MXI-Express is based on PCI Express technology. A MXI-Express kit uses a PCI Express
switch and PCI Express-to-PCI bridge to enable control of a PXI or CompactPCI chassis from
a PC with an available PCI Express slot. The PCI Express-to-PCI bridge architecture is
transparent to device drivers, so no additional software is needed to support using PXI and
CompactPCI devices in a chassis connected using MXI-Express.
The link between the PC and the chassis is a x1 cabled PCI Express link. This link is a
dual-simplex communication channel comprised of a low-voltage, differentially driven signal
pair. The link can transmit at a rate of 2.5 Gbps in each direction simultaneously.
MXI-Express Cable Options
MXI-Express is available with cables of various lengths. Table 2-2 shows the cables available
from National Instruments.
