Be sure not to insert the power module with its front panel upside down. 

Follow the forward inertia of the power module when inserting it into the chassis to ensure that the 

power module has firm contact with the connector on backplane. 

To prevent damage to the power module and the connection terminals on the backplane, make sure to 

pull the module out first in case of any misalignment, and then push it in again. 

 

3)  Tighten the captive screws with a screwdriver to secure the power module to the chassis. 

 

If the captive screws cannot be tightened, check whether the power module is properly installed.
