AC power LED
This light provides status information about the power supply. During
normal operation, both the AC and DC power LEDs are on. See “Power
supply LEDs” on page 95 for more information.
DC power LED
This light provides status information about the power supply. During
normal operation, both the AC and DC power LEDs are on. See “Power
supply LEDs” on page 95 for more information.
Adding a power supply
If you replace the power supply backplane with the power supply backplane option,
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 can also add a third power supply for additional
capacity. After you install a power supply, verify that the power-supply status
indicators (AC Power light and DC Power light) are lit, indicating that the power
supply is operating properly.
Notes:
1. You do not need to turn off the power to the server to install hot-swap power
supplies.
2. The illustrations in this document might differ slightly from your hardware.
