Install the Mounting Shelf in a Rack

The following table specifies the holes in which you insert cage nuts and screws to install the mounting hardware required
(an x indicates a mounting hole location). The hole distances are relative to one of the standard U divisions on the rack.
The bottom of all mounting shelves is at 0.02 in. (0.05 cm) above a U division.

1. If needed, install cage nuts in the holes as specified in the table.

2. On the back of each rack rail, partially insert a mounting screw into the lowest hole specified in the table.

3. Install the mounting shelf on the back of the rack rails. Rest the bottom slot of each flange on a mounting screw.

4. Insert screws into the open holes in each flange of the mounting shelf.

5. Tighten all the screws completely.

Mount the EX9204

1. Safely remove all components—power supplies, Switch Fabric (SF) module, fan tray, air filter, and line cards—from the

2. Ensure that the rack is properly secured to the building in its permanent location.

3. Ensure that a mounting shelf is installed to support the weight of the chassis.

NOTE: An empty chassis weighs approximately 52.02lb (23.60 kg) and a fully loaded chassis weighs approximately

128.08 lb (58.1 kg). We strongly recommend that you use a mechanical lift or have at least three persons to lift
the chassis, and remove all the components from the chassis before mounting.

NOTE: While mounting multiple units on a rack, mount the heaviest unit at the bottom and mount the other

units from the bottom to the top in decreasing weight order.

chassis.

4. Position the chassis in front of the rack, centering it in front of the mounting shelf.

5. Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the mounting shelf, and position it as close as
possible to the shelf.

6. Carefully slide the chassis onto the mounting shelf so that the bottom of the chassis and the mounting shelf overlap
by approximately 2 in. (5.08 cm).

7. Slide the chassis further until the mounting brackets touch the rack rails. The shelf ensures that the holes in the mounting
brackets and the front-mounting brackets of the chassis align with the holes in the rack rails.

8. Install a mounting screw into each of the open mounting holes aligned with the rack, starting from the bottom. Ensure
that all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side and
the chassis is level. Tighten the screws.

9. Reinstall the chassis components. Ensure that all empty slots are covered with a blank panel before operating the
switch.

Connecting EX9204 to AC power

NOTE: Do not mix AC and DC power supplies in the same switch.

1. Attach an ESD wrist strap to your bare wrist, and connect the strap to the ESD points on the chassis.

2. Set the power switch of the AC power supply to the OFF (0) position.

3. Insert the coupler end of the power cord into the AC power cord inlet on the AC power supply faceplate.

4. Insert the power cord plug into the power source outlet and switch on the dedicated customer site circuit breaker.
