Your server comes with one power supply, installed in bay 3. You can replace the
power supply backplane with an optional backplane that will enable you to add a
second power supply, which gives redundancy and will make the power supplies hot-
swappable. You also can add a third power supply for additional capacity. Each
power supply has two status indicators; see the following illustration for information
about the status indicators and power supply bay locations.
Note:
The illustrations in this document might differ slightly from your hardware.

supply bays.
