6. Carefully press the LSIiBBU09 unit onto the RAID controller so that the two connectors are firmly joined.
7. Secure the LSIiBBU09 unit to the RAID controller with the screws and the standoffs in the three screw holes.
The standoffs are threaded at both ends, and a screw goes into each end. The screw threads from the back of the
controller board into the board-to-board standoffs on the bottom of the LSIiBBU09 unit.
Center the screwdriver carefully to avoid stripping the screw heads. Do not over-tighten the screws.
5.2.3 Reinstalling the RAID Controller on the Motherboard
Follow these steps to reinstall the RAID controller on a motherboard.
1. Make sure that the power to the chassis is still turned off, the power cords are unplugged, and the chassis is
grounded and has no AC power.
2. Install the RAID controller in a PCI Express slot on the motherboard, as shown in the following figure.
3. Press down gently, but firmly, to seat the card correctly in the slot.
4. Secure the controller to the computer chassis.
NOTE Some PCI Express slots support only PCI Express graphics cards. If a RAID controller is installed in
one of these slots, the controller will not function. Refer to your computer documentation for information
about the PCI Express slot.
