Grounding the Router
14
Installing Cisco 3800 Series Routers in an Equipment Rack
OL-5969-01
Install the router in the rack, using two screws for each side. Rack-mounting screws should be supplied
with the rack; they are not provided with the router.
Caution
Be sure to leave space above and below each router in a rack, to allow for cooling air circulation.
Tip
Start the lower pair of screws first. Rest the brackets on the lower screws while you insert the upper pair
of screws.
Attaching the Optional Cable Management Bracket
The optional cable management bracket (Cisco 3825 router only) provides attachment points for
organizing and routing cables. Attach the cable management bracket to the left or right rack-mount
bracket using the screw provided. You can attach the cable management bracket to either the upper or
lower threaded hole. See
for attachment locations.
