Attaching Brackets
Attach the mounting brackets to the chassis as shown in Figure 2, Figure 3, Figure 4, or Figure 5, using the screws provided in
the bracket kit. Use a number 2 Phillips screwdriver to install the bracket screws.
Caution Your chassis installation must allow unrestricted airflow for chassis cooling. For mounting in a 19-inch rack, be
sure to install the wide bracket (marked RIGHT) on the side where the cooling fans are located. For installation on
a desktop, keep at least 1 inch of clear space beside the cooling fans.
