Figure 4-10 Removing the speaker
Power supply
1. Disconnect power from the system ( Pre-disassembly procedures on page 53), and remove the
access panel (
Access panel on page 58). Place the workstation on its side with the system board
facing up.
2. Disconnect the power supply from the system board.
CAUTION Be sure you can differentiate which power cable was disconnected from the
PCI Express x16 graphics card and which power cable was disconnected from the system
board. These two cables look similar. The PCI Express power cable has a black connector,
and the power cable has a white connector. When power is present, NEVER connect the
PCI Express power cable to the system board. If you do so, the system board can be
damaged and your warranty voided. To see a picture of the PCI Express cable and where
it must be connected, see the
PCI or PCI Express installation on page 73.
3. Disconnect the optical drives, diskette drive, hard drives, and graphics card (select models only)
from the power supply.
4. Remove the four screws (1) from the back panel.
5. Slide the power supply toward the front, and lift up (2) to remove it from the chassis.
