What to Do
Note – If a power supply has failed and you do not have a replacement available,
leave the failed power supply installed, or replace it with a filler panel.
1. Identify the power supply that you want to remove.
2. Unlock the system doors and swing them open.
Turn the keyswitch to the Power-On/Off position. This unlocks the system front
access doors.
3. Loosen the Phillips screw that secures the power supply retaining clip until you
can push the clip up.
4. Using your thumb, push up the retaining clip until it clears the power supply.
Hold up the retainer clip with your thumb as you slide out the power supply from
its bay.
5. With your other hand, rotate the power supply handle so that it is perpendicular
to the front face of the unit.
