CAUTION:

Power supplies are easy to install and remove, but they are not hot-swappable. Always disconnect all server power cords and all power supply power cords before you remove or install a power supply.

Your server comes with two nonredundant power supplies. You may add a third power supply to generate redundant power. After you install power supplies, check the power-supply status indicators to verify that the power supplies are operating properly. See “Identifying Problems through Status Indicators” on page 258 for details.
