Replacing the System-Fan Bracket

CAUTION: See "Protecting Against Electrostatic Discharge" in the safety instructions in your System Information document.

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.

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.

Removing a Power Supply

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.

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).
