Replacing a failed power supply
Before you begin
When you replace a failed power supply, do not unplug the power supply unit that is working. This
action disrupts service to the appliance.
Procedure
1. Remove the failed power supply from the power supply bay by pinching the side clip and pulling the
failed power supply from the bay, as shown in Figure 2.
Important:
During normal operation, each power supply bay must contain either a power supply or a power
supply blank for proper cooling.
