    Installing the Top and Bottom Plenums

    Caution: At least two people are needed to safely install the air deflector kit into the rack. One must hold the front and the other the rear.

    Note: Ensure that the top and bottom plenums are placed such that the side facing up shows the model number of the services gateway. For example, if you are using the SRX5400 Services Gateway, ensure that the plenums are placed such that the side facing up shows the model number (THIS SIDE UP: SRX5400).

    Caution: Do not change the orientation of the top and bottom plenums as it will result in reversal of air flow, misdirecting air intake from the rear and exhaust from the front.

    You can install the top and bottom plenums of the air deflector kit by following this procedure.

    1. Replace the front mounting brackets of the services gateway with the deeper front mounting brackets supplied with the Air Deflector Kit for NEBS compliance, and to ensure all the vents on the sides of the services gateway are closed. See Figure 1.

      Note: If you do not use the deeper front mounting brackets, then air flow performance of the Air Deflector Kit will be adversely affected.

      If you are using an SRX3600 Services Gateway, use the deeper front mounting brackets with part number 540–059543. If you are using an SRX5400 Services Gateway, use the deeper front mounting brackets with part number 540–059544 and 540–059545.

    3. Install the bottom plenum into the rack such that the side facing up shows the model number as shown in Figure 2.
    4. Mount the rear of the bottom plenum to the rear mounting brackets already installed, and secure them with the pan-head screws provided.
    5. Mount the front of the bottom plenum to the front rack post, and secure them with the pan-head screws provided.
    6. Using a mechanical lift, position the services gateway in front of the rack, as close as possible to the bottom plenum.
    7. Carefully slide the services gateway into the rack, using the bottom plenum as the mounting shelf as shown in Figure 3.

    10. Install the rear mounting brackets for the top plenum on the rear rack mounting post as shown in Figure 4.

      Note: Use Figure 4 to guide you through Steps 10, 11, and 12.

    11. Install the top plenum into the rack such that the side facing up shows the model number as shown in Figure 4.
