Installing the PCI riser board assembly
CAUTION: To prevent damage to the server or expansion boards, power down the server and
remove all AC power cords before removing or installing the PCI riser board assembly.

2. Remove the access panel (" Removing and replacing the access panel " on page 26 ).
3. Remove the upper tray (" Removing the upper tray " on page 27 ).
4. Install the expansion board (" Installing an expansion board " on page 34 ).
5. Install the PCI riser board assembly in the server, and tighten the thumbscrews.
6. Replace the upper tray (" Removing the upper tray " on page 27 ).

Hard drive options
The server supports up to 12 SAS or SATA hard drives. Always populate hard drive bays starting with the
lowest device number ("
SAS and SATA drive numbers " on page 8 ).
SAS and SATA hard drive guidelines
When adding hard drives to the server, observe the following general guidelines:
• The system automatically sets all device numbers.
• If only one hard drive is used, install it in the bay with the lowest device number.
• Drives must be the same capacity to provide the greatest storage space efficiency when drives are
grouped together into the same drive array.
NOTE: ACU does not support mixing SAS and SATA drives in the same logical volume.
