Installing the Router in a Rack
Warning
To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to
ensure that the system remains stable. The following guidelines are provided to ensure your safety:
• This unit should be mounted at the bottom of the rack if it is the only unit in the rack.
• When mounting this unit in a partially filled rack, load the rack from the bottom to the top with the heaviest component
at the bottom of the rack.
• If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
Statement 1006
Be sure to leave space above and below each router in a rack, to allow for cooling air circulation.
Caution
Use two screws for each side (supplied with the rack, not with the router).
Start the lower pair of screws first, and rest the brackets on the lower screws while you insert the upper pair of screws.
Tip
Attaching the Cable Management Bracket
The optional cable management bracket 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 the lower threaded hole. See Figure 9 for attachment locations.
