Telco 2-Post Rack

Item a in the above figure shows a telco-style rack. The telco-style rack is an open frame consisting of two
posts tied together by a cross-bar at the top and a floor-stand at the bottom.
This type of rack is usually secured to the floor, and sometimes to an overhead structure or wall for additional
stability. The router chassis can be installed in the telco-style rack only in a front-mounted position.
In the front-mounted position, you secure the chassis rack-mounting brackets directly to the rack posts (see
the following figure as an example of a Cisco ASR 9001 Router rack mounting). Two rear mounting brackets
are provided for mounting the Cisco ASR 9001 Router in a 2-post rack.
