Installation
3-1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic components. To avoid dam-
aging your controller card, it is important to handle it very carefully. The following
measures are generally su󰀩cient to protect your equipment from ESD.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing the controller card from the
antistatic bag.
• Handle the controller card by its edges only; do not touch its components or
peripheral chips.
• Put the controller card back into the antistatic bags when not in use.
• For grounding purposes, make sure that your system chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the controller card.
Unpacking
The controller card is shipped in antistatic packaging to avoid static damage. When
unpacking your component, make sure you are static protected.
Note: To avoid damaging your components and to ensure proper installation, be
sure to always connect the power cord last, and always remove it before adding,
removing or changing any hardware components.

3-2 Before Installation
To install the controller card properly, follow the steps below.
Prior to Installation
1. Power down the system and unplug the power cord.
2. Use industry-standard anti-static equipment (such as gloves or wrist strap)
and follow the precautions on page 3-1 to avoid damage caused by ESD.
3-3 Installing the Controller Card
Depending upon which system conguration is used, a riser card may or may not
be required to install the AOC-S3816L-L16iT/AOC-S3808L-L8iT.
Installing the Controller Card
1. Power down the system, remove the power cords from the rear of the power
supply, and remove the system cover.
2. Verify that your controller card is equipped with the correct length of PCIe slot
mounting bracket for your system. The AOC-S3816L-L16iT/AOC-S3808L-L8iT
controller card includes a low-prole PCIe mounting bracket. However, if your
system features full-height PCIe slots, replace the low-prole bracket with a
full-height bracket.
3. Insert the controller card into a x8 PCIe slot.
4. Connect the SAS interface cables from the controller card to either the direct
attached storage target devices or the cable sockets on the backplanes.
5. The cable latch will click into the locked position when connected properly.
6. Replace the system cover, plug in the power cord, and power up the system.
