Removing a Redundant Power Supply
NOTICE: The system requires one power supply to operate the system normally. On
power-redundant systems, remove and replace only one power supply at a time in a
system that is powered on.
NOTICE: If you are replacing a redundant power supply while your system is on,
ensure that both the power supply status and the AC line status LEDs are green
before removing the power supply (see Figure 1-3). If one or both of the LEDs are
not green, see "Troubleshooting Redundant Power Supplies" on page 143.
