Put your forefinger into the hole in the filler panel and then pull the filler panel out of the slot

3.
Unpack the power supply. Make sure the power supply model is as required.
Keep the packaging box and packaging bag for the power supply secure for future use.
4.
Correctly orient the power supply. Make sure the lettering on the power supply is upward.
5.
Align the power supply with the power supply slot. Grasping the handle of the power supply with
one hand and supporting its bottom with the other, slide the power supply slowly into the slot
along the guide rails until the latch of the power supply clicks into the slot.
To prevent damage to the power supply or the connectors on the backplane, insert the power
supply gently. If you encounter a hard resistance when inserting the power supply, pull out the
power supply and insert it again.
