Motherboard Installation

This section explains the first step of physically mounting the StorTrends 1100
motherboard into the StorTrends 1100 chassis. Following the steps in the order given will
eliminate the most common problems encountered in such an installation. To remove the
motherboard, follow the procedure in reverse order.

1. Accessing the inside of the 1100 (see Figure 2-5)

Two release buttons are located on the top cover of the chassis. Depressing both of these
buttons while pushing the cover away from you until it stops. You can then lift the top
cover from the chassis to gain full access to the inside of the server. (If already installed
in a rack, you must first release the retention screws that secure the unit to the rack. Then
grasp the two handles on either side and pull the unit straight out until the rails lock into
place.)

2. Check compatibility of motherboard ports and I/O shield:

The StorTrends 1100 motherboard requires a chassis big enough to support a 12" x 9.5"
motherboard, such as American Megatrends StorTrends 1100 1U rackmount. Make sure
that the I/O ports on the motherboard align properly with their respective holes in the I/O
shield at the back of the chassis.

3. Mounting the motherboard onto the motherboard tray:

Carefully mount the motherboard to the motherboard tray by aligning the board holes
with the raised metal standoffs that are visible on the bottom of the chassis. Insert screws
into all the mounting holes on your motherboard that line up with the standoffs and
tighten until snug (if you screw them in too tight, you might strip the threads). Metal
screws provide an electrical contact to the motherboard ground to provide a continuous
ground for the system.
