Installing Your Mainframe Extender

Caution To guard against electrostatic discharge, touch the antistatic plastic package to a
metal part of your chassis before removing the module from the package. Your VXI or
VME chassis should be plugged in but powered off.
Having more than one device configured as system controller can damage the

VXI/VME system.
PCI-Based MXI-2 Interfaces for Windows 2000/NT/Me/98
Install the PCI-MXI-2 or PXI-8320 in an available peripheral slot in your
PCI-based computer or PXI/CompactPCI chassis. For more information,
refer to the PCI-MXI-2 or PXI-8320 chapter in the MXI-2 Configuration
Reference Manual.
You also received either a VXI-MXI-2, VXI-MXI-2/B, or VME-MXI-2 in
your kit.
Install the VXI-MXI-2 or VXI-MXI-2/B in the first slot of a VXI chassis,
or install the VME-MXI-2 in the first slot of a VME chassis.
The VXI/VME-MXI-2 default configuration automatically detects whether
it should be the VXI/VMEbus system controller. The VXI/VMEbus system
controllers operate certain VXI/VMEbus lines as required for VXI/VME
systems. Verify that any other VXI/VME devices with system controller
capability that are in the same chassis are not configured as system
controller.
For VXI systems that include VME devices, ensure that the VME devices
are not configured in the upper 16 KB (starting from 0xC000) of the
A16 address space. This region is reserved for VXI device configuration
registers, which are used for initializing, configuring, and interacting with
VXI devices. The PCI-MXI-2, PXI-8320, and VME-MXI-2 all use this
region for this purpose.
Also ensure that no VXI devices in your system are configured for either
logical addresses 0 or 1. These are the default configurations for the
PCI-MXI-2 or PXI-8320 and the VXI-MXI-2, respectively.
For more information, refer to the VXI-MXI-2, VXI-MXI-2/B, or
VME-MXI-2 chapter in the MXI-2 Configuration Reference Manual.
