4.Swing the flip latch up and gently tighten the captive screw into the module. DO NOT overtighten this screw.

Note: The flip latch will not engage if the power module is not fully seated into the bay. The flip latch activates a micro switch inside the power module. If the latch is not properly installed, the power module will not function. If the flip latch will not engage, pull the power module partially out, and firmly slide it back into place.
