SCXI-1127/1128 User Manual 1-16 ni.com
Notes Do not connect the SH9MD-9MD cable to the 2-slot HVAB-backplane adapter.
An SCXI-1127/1128 is required in slot 12 of each 12-slot chassis to establish
communications with all the chassis in the system. If slot 12 is empty, the chassis will not
operate. It is this module that you must specify in MAX as the module cabled to the DMM.
If a chassis is configured with less than 12 slots of the HVAB-backplane adapter, use the
right-most available HVAB connector to extend to the next chassis. In this instance,
right-most means the slot closest to slot 1 when the chassis is viewed from the back.
Connecting the SCXI-1127/1128 to the DMM in a PXI-1010 Chassis
You need the following items to complete the installation:
•PXI chassis with the SCXI-1127/1128 modules installed
•SCXI-1357 kit

SCXI modules should already be installed in the chassis according to their
installation instructions. Before you proceed with your connections, make
sure you turn off your SCXI chassis.
