9. Inspect the hard drive assembly to verify the following items:
■ The metal locking handle is fully closed.

Instructions” on page 5-5.
5.5 Installing SAS Card, Cables, and Hard
Drives
To replace the SATA drives with SAS drives, use the following procedure. You will
need to order a SAS installation kit that includes a SAS PCIe card, and SAS HDDs.
The following procedure describes how to modify the current installation and install
the SAS components:
1. Power off the system, open and position the chassis, and remove the access panel.
See Section 5.2.2, “Powering Off the System and Removing the Left Side Access
Panel” on page 5-3.
2. Remove the SATA HDDs from the drive bay.
See Section 5.4.1, “Removing a Hard Disk Drive” on page 5-8
3. Move the HDD cables from the motherboard to the SAS card as follows:
a. Release the HDD cables from the tiedowns (2 places).
b. Disconnect the SATA1 (blue connector) cable from the motherboard SATA1
connector and install it on PHY0 of the SAS card.
c. Disconnect the SATA2 (green connector) cable from the motherboard SATA2
connector and install it on PHY1 of the SAS card.
Note – To ease the installation process, connect the cables to the SAS before
inserting the card in the PCI slot.
4. Locate the PCI-E2 slot.
PCI-E2 is the preferred slot. This x8 slot should be used because it is best to reserve
PCI-E0 (x16) for the graphics card, but the card will work in either slot.
See FIGURE 5-7 for PCI card locations.
