Removing a Power Supply
Step 2
To unseat the power supply from the power shelf connector, unlatch the power supply door grille latch
and open it completely. See
Figure 2-25
for an illustration of the power supply grille and door latch.
Note
The power supply fans may continue to turn at high speed for a few seconds after they are
unseated from the power shelf.
Step 3
Grasp the power supply door grille and gently pull the power supply halfway from the bay.
Caution
Take care when handling a power supply that has recently been in use; it can be hot to the
touch.
Caution
A power supply weighs about 4.6 lb (2.1 kg). You should use two hands when handling a
power supply.
Step 4
Use your free hand to support the power supply while you slide the power supply completely from the
bay, then set the power supply safely aside.
What to Do Next
After performing this task, you may install a new power supply, if needed (see the
“Installing a Power
Supply” section on page 2-28
), and replace any front cosmetic covers.
