Before you begin
The rear mounting brackets (UCSX-9508-RACKBK) are a customer orderable option for systems that are
shipped pre-installed in a rack.
Step 1 At the rear of the chassis, use your hands to install each rear mounting bracket, which has a folded tab at the top and a
folded metal hook at the bottom.
a) Slide the hook the into the cutout in the chassis side wall.
b) Slide each rear mounting bracket until the tab seats into the emboss in the chassis top.
