Installing the Chassis in a Two-Post Rack
Procedure
Step 1 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.
Step 2 Use two persons to lift the chassis into the rack holding the top and bottom of the chassis (see the figure
below).

Caution
Step 3 Position the chassis until the rack-mounting flanges are flush against the mounting rails on the rack.
Step 4 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.
Step 5 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 (see the figure below).
Step 6
Fully tighten all the screws on the chassis mounting flanges and bracket flanges (each side) to secure the
chassis to the rack rails.
