Installing System Components 63
• For up to four SAS or SATA drives in a level 0 or 1 RAID configuration, connect the cables to an
optional SAS controller card (see "Installing an Expansion Card" on page 57) installed into
expansion slot 4 (PCIE_X4_4), and connect the hard-drive activity LED cable to the connector on
the system board and the connector on the card itself. Route the cables through the center fan
retention cage. See Figure 3-13.
NOTE: The optional SAS controller card supporting up to four SAS or SATA drives in a RAID configuration
and illustrated in Figure 3-13 should only be installed into slot 4 (PCIE_X4_4). The optional integrated SAS
RAID controller daughter card illustrated in Figure 3-14 should only be installed into the integrated daughter
card slot (INT_STORAGE) on the system board. See Figure 6-2 for the locations of these connectors.
