Note: You must install the fan assembly before removing or installing the power supply.

page 34.
Attention: Static electricity that is released to internal server components when the server is

potential problem, always use an electrostatic-discharge wrist strap or other grounding system
when you work inside the server with the power on.
Step 2. Touch the static-protective package that contains the hot-swap power supply to any unpainted
metal surface on the server; then, remove the power supply from the package and place it on
a static-protective surface.
Step 3. Remove the power-supply filler panel from the power bay, if one is installed.
Step 4. Install the power supply and push it in until it locks into place.
Notes:
• If only one hot-swap power supply is installed in the server, a power-supply filler must be
installed in the empty power bay.
