Note
Do not use the SH9MD-9MD cable behind slot 4 of the 2-slot HVAB-backplane
adapter on the 12-slot chassis.
An SCXI-1127 is required in slot 4 of the 4-slot chassis and slot 12 of the 12-slot
chassis to establish communications with all the chassis in the system. If slot 4 is
empty in the 4-slot chassis or slot 12 is empty in the 12-slot chassis, the chassis will
not operate. It is this module that you must specify in the configuration utility as
the cabled module to the DMM.
If the 4-slot chassis is configured with less than four 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.
