Telco 2-Post Rack Item a in Figure 1-17 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 Figure 1-18 for the Cisco ASR 9010Router, Figure 1-19 for the Cisco ASR 9006 Router, and
Figure 1-20 for the Cisco ASR 9904 Router). Two rear mounting brackets are provided for mounting the
Cisco ASR 9010 Router in a 2-post rack.
Note The mounting brackets on the Cisco ASR 9006 Router chassis have a pair of holes at the top and bottom
of each bracket; the remaining openings in the brackets are slots. When mounting the router in a 2-post
rack, you must first use the holes to locate and position the brackets on the rack. Insert the screws through
the bracket holes into the rack before inserting screws through the bracket slots.
