Figure 1-7 Cisco ASR 9001 Router Mounted in a 2-Post Rack

Open 4-Post Rack

Item b in Figure 1-6 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.

Enclosed Rack with Perforated Sides
