Chapter 2 Hardware Configuration and Installation

Step 5. Connect the MXIbus Cable

There are two basic types of MXIbus cables. MXIbus cables can have either a single connector
on each end or a single connector on one cable end and a double connector on the other end.
Your VME-SB2020 kit comes standard with a cable with single connectors on each end.

Nonpolarized Cables

The cable with a single connector on each cable end is nonpolarized and can be installed with
either end connected to either device. Be sure to tighten the screw locks to ensure proper pin
connection.

Polarized Cables

If you are using a MXIbus cable with a single connector on one cable end and a double
connector on the other end, it is a polarized cable that must be installed correctly for the system
to function properly. Connect the end with the single connector to the SB-MXI and the end of
the cable with the double connector to the VME-MXI. Be sure to tighten the screw locks to
ensure proper pin connection.
When the MXIbus cable is properly connected, turn on the VME chassis and the Sun
workstation. After all devices are powered on and running properly, you can run the the
Resource Manager software utility to configure the system.
