Bracket Installation for Center-Rear Mounting
Mounting the Router in a Rack
After you attach the rack-mount brackets to the router chassis, use the screws provided with the rack to
install the chassis in the rack. (See
Figure 3-12
.)
Tip
For 23-inch SBC brackets start the lower pair of screws first, and rest the brackets on the lower screws
while you insert the upper pair of screws.
Tip
The screw slots in the brackets are spaced to line up with every
second
pair of screw holes in the rack.
When the correct screw holes are used, the small threaded holes in the brackets line up with unused screw
holes in the rack. If the small holes do not line up with the rack holes, you must raise or lower the
brackets to the next rack hole.
