Remove/Replace System Components Removing/Replacing System Components 4. Unscrew the four power supply mounting screws located on the back of the system. See Figure 1-48. Note that there is a power supply support arm that ﬁts into a slot on the system divider panel. This support arm prevents the supply from falling onto the system board while you are unscrewing the mounting screws. Figure 1-48. Unscrewing the Four Power Supply Mounting Screws Power Supply Support Arm System Divider Panel Power Supply Mounting Screws 5. Remove the AC power supply from the system. To do this, you will have to slide the support arm out of its slot. See Figure 1-49. Note that there is a component heat sink located on the system board near the back of the power supply that can be damaged if you are not careful when removing the power supply. See Figure 1-49.

4. Unscrew the four power supply mounting screws located on the back of the system. See

Figure 1-48. Note that there is a power supply support arm that ﬁts into a slot on the

system divider panel. This support arm prevents the supply from falling onto the

system board while you are unscrewing the mounting screws.
