Field Replaceable Units FRU Removal and Replacement Removing the Fan and Speaker from the I/O Card Area The I/O area of the system unit has its own cooling fan. Note that there is a speaker attached to the same mounting bracket as the fan. This section explains how to remove the fan and speaker if they are defective. To remove the I/O cooling fan or speaker, do the following: 1. Remove the workstation left side panel. See the section "Opening the Left Side Panel of the System" in this chapter. 2. Lay the workstation on its side, and remove all of the I/O cards. See the section "Removing I/O Cards" in this chapter. 3. Remove the system unit air divider as shown in Figure 4-19 by unscrewing the two T-15 Torx screws, which hold it in place. Next grasp the edge of the air divider and pull it towards you. Figure 4-19. Removing the System Unit Air Divider T-15 Screw T-15 Screw Air Divider 4. Remove the fan and speaker cables from the system board and lift up on the bracket mounting clip. See arrow in Figure 4-20. Next grab hold of the fan and speaker bracket and rotate it about 15 degrees to the left. See the arrow in Figure 4-20. The fan and speaker bracket should now be free of the clip retainer hole and the bracket stop. Now move the whole mounting bracket to the left or toward the back of the CD Drive chassis. The fan and speaker mounting bracket is now free of the system unit. 114 Chapter 4

Field Replaceable Units

FRU Removal and Replacement

Removing the Fan and Speaker from the I/O Card Area

The I/O area of the system unit has its own cooling fan. Note that there is a speaker

attached to the same mounting bracket as the fan. This section explains how to remove the

fan and speaker if they are defective.

To remove the I/O cooling fan or speaker, do the following:

1. Remove the workstation left side panel. See the section “Opening the Left Side Panel of

the System” in this chapter.

2. Lay the workstation on its side, and remove all of the I/O cards. See the section

“Removing I/O Cards” in this chapter.

3. Remove the system unit air divider as shown in Figure 4-19 by unscrewing the two T-15

Torx screws, which hold it in place. Next grasp the edge of the air divider and pull it

towards you.

Figure 4-19. Removing the System Unit Air Divider
