Chapter2 Unpacking and Installing the Chassis
Installing the Cisco ASR 9001 Chassis
Installing the Chassis in a Two-Post Rack
Before you install the chassis in the rack, make sure that you have the necessary tools and equipment
(see Before you Begin, page2-4).
Note Six mounting bracket screws (three per side) are provided to attach the chassis to the rack. If the
bracket holes do not line up with the rack rails, make sure that you attach a minimum of four
screws (two screws per bracket) on each side.
To install the chassis in a two-post rack, follow these steps:
Step1 Attach the mounting flanges to the chassis by using the Cisco-supplied screws.
To accommodate racks with different hole patterns in their mounting flanges, the chassis rack-mounting
flanges have three oblong screw holes on each side.
Step2 Use two persons to lift the chassis into the rack holding the top and bottom of the chassis (Figure2-3).
Figure2-3 Correct Lifting Positions
Caution Do not grasp air inlet or exhaust when lifting the router chassis.
Step3 Position the chassis until the rack-mounting flanges are flush against the mounting rails on the rack.
Step4 Hold the chassis in position against the mounting rails while the second person finger-tightens a screw
to the rack rails on each side of the chassis.
Step5 Finger-tighten two more screws to the rack rails on each side of the chassis. Space the screws evenly
between the top and bottom of the chassis (Figure 2-4). I
