Replacing the Full-Height Bracket with a Low-Profile Bracket
If you are installing your SAS Expander Card into a low-profile computer cabinet, replace the original
full-height bracket with the low-profile bracket included in your distribution kit. The full-height bracket
is mounted on the front of the expander, the low-profile bracket is mounted on the back, as shown in
the figures below.

To replace the full-height bracket with the low-profile bracket:
1. Remove the full-height bracket from the expander card. The full-height bracket is installed on the
front side of the expander, with the mounting screws inserted from the back (see Figure 1). Using
a Phillips head screw driver, remove the mounting screws, as shown in Figure 2, then set the screws
aside for use in the next step.
