Mounting the Brackets on the NCS 2015 Shelf

This chapter describes how to mount the brackets on Cisco NCS 2015 shelf.


Caution

Use only the fastening hardware provided with the NCS 2015 shelf to prevent loosening, deterioration, and electromechanical corrosion of the hardware and joined material.


Caution

When mounting the NCS 2015 shelf in a frame with a nonconductive coating (such as paint, lacquer, or enamel) either use the thread-forming screws provided with the NCS 2015 shipping kit, or remove the coating from the threads to ensure electrical continuity.


Warning

Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over. Statement 1048


Warning

This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation. Install only in accordance with national and local wiring regulations. Statement 1045
