Replacing the System-Fan Bracket
1. Replace the system-fan bracket (see Figure 4 -9 ):
a. Lower the bracket into the chassis, hooking the top bracket tabs into the slots in the rear chassis wall.
b. Swing the bottom of the bracket toward the rear chassis wall until the two side bracket tabs snap into place on the rear wall.
2. Replace the two system fans (see " Replacing a Cooling Fan ").
Power Supplies
The system includes one or two hot-pluggable power supplies.
Removing a Power Supply
1. Squeeze the latch at the bottom of the power-supply handle.
2. Rotate the power-supply handle up until the power supply is released from the chassis (see Figure 4 -10 ).
3. Pull the power supply straight out to clear the chassis (see Figure 4 -10 ).
Figure 4-10. Removing and Installing a Power Supply
CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.
CAUTION: DC power supplies require a safety ground wire connected to the grounding post on the system (see Figure 3 -3 ). An energy hazard
will exist if the safety ground cable is omitted or disconnected. For more information, see the DC power supply documentation.
NOTICE: The power supplies are hot-pluggable. The system requires one power supply to be installed for the system to operate normally. The system
is in the redundant mode when two power supplies are installed. Remove and replace only one power supply at a time in a system that is powered on.
