Figure 49 The Location of CPU Fan 0, CPU Fan 1, Power Headers, and the Positioning of Power Cables
Perform the following steps to replace a fan.
1. Power off the blade and remove it from the chassis. Place the blade on a stable
surface, such as a desk or a bench.
2. Position the blade so the hard disk tray is facing up (the hard disk tray is located
on the left side of the blade when you are looking at the front of the blade).
3. Use a a Phillips screwdriver to remove the four screws from the hard disk tray.
4. Use the finger holes in the center of the tray to carefully raise the tray. Do not pull
the tray straight up; rotate the tray on its long edge as shown in Figure 46 on page
86. Remove SATA data cables and power cables from the hard disks.
5. Remove each fan’s power cable from the fan headers located on the motherboard.
Carefully use your fingers or needle-nose pliers to gently pull back on the
header’s release tab, located in front of the cable.

NOTE
Before disconnecting any SATA cables, mark them so you can
easily reconnect each cable to the correct hard disk. Figure 45
on page 85 shows hard disk numbering.
