Install the Module
Complete these steps to install the 1756-DHRIOXT module.
1. Align the circuit board with top and bottom guides in the
chassis.
2. Slide the module into the chassis.
3. Verify that the module backplane connector properly connects
to the chassis backplane.
The module is properly installed when it is flush with the
power supply or other installed modules.
ATTENTION Do not force the module into the backplane connector. If you cannot seat the
module with firm pressure, check the alignment. Forcing the module into the
chassis can damage the backplane connector or the module.
