20 Installing the S25P
Four-Post Rack-mounting with Threaded Rails
Ensure that there is adequate clearance surrounding the cabinet or rack to permit access and airflow. If you
are installing two S25P switches side-by-side, position the two S25P chassis at least 5 inches (12.7 cm)
apart to permit proper airflow. Follow the steps below to install a switch into a 4-post 19-inch equipment
rack, using the attached front mounting brackets and the optional adjustable rear-mounting brackets.
Step Task
1
Align the three screw holes of the adjustable rear mounting bracket with the three holes in the S25P chassis, and
secure the mounting bracket with three screws.

the rear posts with two screws.
