1. Install the 8-slot HVAB-backplane adapter behind slots 5 through 12.

2. Install additional 2-slot and 1-slot HVAB-backplane adapters behind

slots 1 through 4 if needed.

3. Install the 8-position HVAB plugs to connect the HVAB-backplane

adapters as needed.

4. Connect the HV8-BAN4 cable from the DMM to the HVAB connector

behind slot 12.

5. Connect the SH9MD-9MD cable from the DMM to the AUX IN

connector behind slot 5.

6. You can install any additional SCXI-1127 modules in any slot that has

an HVAB-backplane adapter behind it.

Notes Do not connect the SH9MD-9MD cable to the AUX IN connector behind slot 4 on

the 2-slot HVAB-backplane adapter.

An SCXI-1127/1128 is required in slot 12 to establish communications with the chassis.

If slot 12 is empty, the system will not operate. It is this module that you must specify in

MAX as the module cabled to the DMM.
