Equipment Rack Types
Telco 2-Post Rack
Item a in 
 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 
 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.
Note
The mounting brackets on the Cisco ASR 9001 Router chassis have a pair of holes at the top and bottom 
of each bracket; the remaining openings in the brackets are slots. If the Cisco ASR 9001 Router is to be 
mounted in a 2-post 19-inch rack, you must first use the holes to locate and position the brackets on the 
rack. Insert screws through the bracket holes into the rack before inserting screws through the bracket 
slots.
