M320 Site Preparation Checklist Requirements on page 41
To prepare to center-mount the router in an open-frame rack, you install both the large
and small mounting shelves. Optionally, you can move the adjustable center-mounting
brackets to any of 11 positions on the side of the chassis. The spacer bars are not needed
to center-mount the chassis; however, you can leave them attached to the front-mounting
flanges.
To prepare to front-mount the router in an open-frame rack, install the large mounting
shelf on the rack. The small mounting shelf and adjustable center-mounting brackets
are needed only if you are center-mounting the router. The spacer bars are not needed.
