If MAX indicates that the MXI-4 connection has timed out, the MXI-4 card
did not detect that it was connected to another MXI-4 card at power-up
time. This can occur if the host chassis is turned on before the expansion
chassis, or if the MXI-4 cable is not plugged in properly. Refer to the
Powering Up the MXI-4 System section of Chapter 2, Hardware and
Software Installation , for more information.
