Step 4 Grasp the terminal block with one hand. Place your other hand underneath as you slide the power supply
module into the bay.
You will hear an audible click sound, which indicates that the module is locked into place, and connected
with the backplane. Only the terminal block housing is not flush with the chassis.
If you do not push the release latch in before you slide the module into the bay, you will not hear the click
sound, but this is an acceptable way of installing the module.

latch.
