Cisco ASR 9001 and Cisco ASR 9001-S Routers Hardware Installation Guide
Chapter1 Preparing for Installation
Site Requirement Guidelines
Note The mounting brackets on the CiscoASR 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.
Figure1-7 Cisco ASR90 01Router 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 CiscoASR 9001 Router in a 4-post rack.
