AC power LED
This light provides status information about the power supply. During typical
operation, the ac power LED is on.
DC power LED
This light provides status information about the power supply. During typical
operation, the dc power LED is on.
Note: If the 385-watt power supply LED is flashing, the system is overloaded
and the power supply will shut down.
Adding a hot-swap power supply
Adding a power supply When the hot-swap power supply backplane is installed, you can replace the 385-watt
power-supply with an optional backplane that will enable you to install up to three
power supplies, which enables redundancy and will make the power supplies hot-
swappable. 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.
