Power Supply Unit
Your server can contain one or two power supply units.
The second power supply unit is optional and provides a redundant configuration that ensures
continued operation of the system in the unlikely event one of the power supply units fails.
Installation
Install the power supply unit in the following procedure.
1. See the section "Preparing for Installation and Removal" described earlier to prepare.
2. Loosen a screw securing the blank cover to remove the cover from the chassis.
IMPORTANT: Keep the removed blank cover for future use.
3. Insert the power supply unit into the vacant slot until it locks.
IMPORTANT: Insert the power supply unit straight into the slot. To
avoid damaging the power supply unit, do not tilt or twist the unit as
you push it into the connector.
