Caution
Do not leave any power supply slot open for any amount of time while the system is powered up. Prior to
inserting a new power supply unit, for instance, when replacing the unit, ensure there are no foreign, conductive
or other objects, or debris in the slot.
Installing a Power Supply Blank Cover
To install a power supply blank cover, push the blank cover straight and into the bay. You will hear it snap
into place when installed correctly. You can hold the blank cover by the outside edges when you perform this
task; alternatively, use the finger holes to hold the blank cover, but do not squeeze the rings.
