Step 4. If PCI riser-card assembly 3 needs to be installed (see "Replacing a PCI riser-card assembly" on
page 172), remember to first install the rear 2.5-inch hot-swap-drive kit. Install the kit by grasping
the two handles located on the sides of the kit, and slowly lower it into the chassis. Make sure that
the two alignment pins securely engage the two holes on the side of the chassis.
Attention: Always follow the installation sequence in this step. Failure to do so, may result in
damage to the rear 2.5-inch hot-swap-drive kit.
