Hardware Installation
To guard against electrostatic discharge, touch the antistatic plastic 
package to a metal part of your computer before removing the PCI-MXI-2 
from the package. Install the PCI-MXI-2 in an available PCI slot in your 
PCI-based computer.
By default, the PCI-MXI-2 automatically detects whether it should be the 
system controller on the MXIbus. Verify that the correct cable end labeled 
Connect This End To Device Closest To MXIbus Controller In This Daisy 
Chain
 is attached securely to the PCI-MXI-2. You must connect the cable 
this way so that the PCI-MXI-2 can correctly detect whether it should be 
the system controller on the MXIbus. For more information, refer to 
Chapter 2, 
You received either a VXI-MXI-2 or a VME-MXI-2 in your PCI-MXI-2 
kit. To guard against electrostatic discharge, touch the antistatic plastic 
package to a metal part of your computer before removing the VXI-MXI-2 
or VME-MXI-2 from the package. Install the VXI-MXI-2 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 located in the same chassis are not configured as system 
controller. Having more than one device configured as system controller 
will damage the VXI/VME system.
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 and VME-MXI-2 also 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 and the VXI-MXI-2, respectively.
For more information about the VXI-MXI-2 or VME-MXI-2 hardware, 
refer to either Chapter 3, 
, or 
Chapter 4,
