Clearance Requirements - Cisco NCS 5500 Series Hardware Installation Manual

Prepare for Installation
To bolt the rack to the floor, a floor bolt kit (also called an anchor embedment kit) is required. For information on bolting
the rack to the floor, consult a company that specializes in floor mounting kits (such as Hilti; see Hilti.com for details).
Make sure that floor mounting bolts are accessible, especially if annual retorquing of bolts is required.

You must provide adequate clearance between the chassis and any other rack, device, or structure inorder to
