Installing the Chassis
Procedure
Step 1 Install the divider bracket between the left and right cable management frames as follows:
a) Position the divider bracket at the bottom of the left and right middle cable management frames (at the
bottom of the supervisor and I/O module area of the chassis) so that the two screw holes in each side of
the bracket align to two screw holes at the bottom of the left and right middle cable management frames
(see the following figure).
Four screw holes on the upper back of the bracket should also align to four screw holes in the chassis.

b) Screw in eight M4 x 13 mm screws to hold this bracket to the bottom of the left middle cable management
bracket (two screws), the bottom of the right middle cable management bracket (two screws), and the
chassis (four screws). Tighten each screw to 11.5 to 15 in-lbs (1.3 to 1.7 N·m).
Step 2 If you also have an air filter kit, install six air filters on the front doors and cable management frames as
explained in
Step 3 Install the door-stop bracket on the top hood of the cable management frames as follows:
a) Position the door-stop bracket under the top hood frame so that its two screw holes align to two screw
holes in the top hood (see the following figure).
Be sure that there is a perpendicular edge facing the front. This edge stops the front doors and provides a
metallic surface for the magnets in the door to hold onto when closed.
