If you are installing the VXI-MXI-2 into a D-size mainframe, install
a support designed for installing C-size boards in D-size mainframes.
The VXI-MXI-2 has no P3 connector and cannot provide P3 Slot 0
control to VXI devices requiring this capability.

Caution
If the VXI-MXI-2 is not configured for automatic Slot 0 detection, be certain that
the slot you select in your VXIbus mainframe matches the VXI-MXI-2 configuration as
either a Slot 0 device or a Non-Slot 0 device. If you install your VXI-MXI-2 into a slot that
does not correspond with the jumper setting, you risk damage to the VXI-MXI-2, the
VXIbus backplane, or both.

4.
Insert the VXI-MXI-2 in the slot you have selected by aligning the
top and bottom of the board with the card-edge guides inside the
mainframe. Slowly push the VXI-MXI-2 straight into the slot until its
plug connectors are resting on the backplane receptacle connectors.
Using slow, evenly distributed pressure, press the VXI-MXI-2 straight
in until it seats in the expansion slot. The front panel of the VXI-MXI-2
should be even with the front panel of the mainframe.

Connect the MXIbus Cable
There are two basic types of MXI-2 cables. MXI-2 cables can have either
a single connector on each end or a single connector on one end and a
double connector on the other end.
a single connector on each end or a single connector on one end and a
double connector on the other end.
Connect the labeled end of the cable to the MXI-2 device that will be the
MXIbus System Controller. Connect the other end of the cable to the other
device. Be sure to tighten the screw locks to ensure proper pin connection.

Figure 3-12 shows the correct cabling for a VXI system containing a
PCI-MXI-2 board in a PCI-based computer cabled to a VXI-MXI-2 module
residing in Slot 0 of a VXIbus mainframe. Notice that you can expand your
system to include other devices by using an additional MXI-2 cable.
However, in such a case the first cable needs to have a double connector on
one end. You can use a cable with a single connector on each end to connect
the last device on the MXIbus.
