5.2 Detailed Installation Instructions
Detailed installation instructions for the LSI PCIe-to-SAS HBA follow.
1. Unpack the HBA and inspect it for damage. Unpack the HBA in a static-free environment. Remove the HBA
from the antistatic bag and carefully inspect it for damage. If you notice any damage, or if any component is
missing, contact LSI or your reseller support representative.
CAUTION Make a backup of your data before changing your system configuration.
2. Prepare the computer. Turn off the computer and disconnect the power cord from the back of the power supply.
3. Remove the cover from the chassis.
WARNING Be certain to disconnect the computer from the power supply and from any networks before
installing the HBA.
4. Replace the mounting bracket (system dependent). If required for your system, replace the full-length
mounting bracket that ships on the LSISAS9205-8e HBA with the shorter bracket supplied. Save and reuse the
two screws that attach the long bracket to attach the short bracket.
5. Insert the HBA in an available PCIe slot. Locate an empty PCIe slot. Remove the blank bracket panel on the back
of the computer that aligns with the empty PCIe slot. Save the bracket screw, if applicable.
Align the HBA to a PCIe slot. Press down gently but firmly to properly seat the HBA in the slot. The following figure
shows how to insert the HBA in a PCIe slot.
