Removing the Center-Mounting Brackets

flange, and two center-mounting brackets attached to the chassis. Remove the center
mounting brackets from the chassis by loosening the screws at the top and bottom of
each bracket.
Installing the Mounting Hardware in an Open-Frame Rack
To install the mounting hardware for an open frame rack:
•
Front-mount: Attach the large mounting shelf on the back of the rails. Remove the
center-mounting brackets from the chassis.
•
Center mount: Attach the large mounting shelf on the back of the rails. You do not
have to remove the center-mounting brackets from the chassis.
The small mounting shelf is not needed for open-frame racks.Table 2 on page 10 specifies
the holes in which you insert mounting screws, and cage nuts if needed.
