The mounting brackets on the Cisco ASR 9001 Router chassis have a pair of holes at the top and bottom
of each bracket and three slots (elongated holes). 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.

Figure 7: Cisco ASR 9001 Router Mounted in a 2-Post Rack
Open 4-Post Rack
Item b in Figure 7: Cisco ASR 9001 Router Mounted in a 2-Post Rack shows a free-standing, 4-post open
rack with two mounting posts in the front and two mounting posts in the back or along the side. The mounting
posts in this type of rack are often adjustable so that you can position the rack-mounted unit within the depth
of the rack rather than flush-mount it with the front of the rack.
Two rear mounting brackets are provided for mounting the Cisco ASR 9001 Router in a 4-post rack.
