1.Turn off the system, including any attached peripherals, and disconnect the power cable from the electrical outlet.

2.Open the system cover.

See your system Installation and Troubleshooting Guide for specific instructions, if needed.

3.Remove the air blower, if present (see Figure 1-4).

a.Unplug the Y-shaped air blower power cable from the interposer board.

b.Position your right thumb on the outside of the power supply enclosure beside the narrower front part of the air blower.

c.Push firmly on the power supply enclosure to move it slightly away from the air blower and allow extra clearance to remove the air blower.

d.With your left hand, pull the front of the air blower upward and away from the power supplies to unseat it. You should hear it unsnap.

By pulling the air blower slightly away from the power supplies, you avoid the need to use excessive force to clear the power supply enclosure.
