Optional air deflector kits are available that let you install the SRX3400 and SRX5600
Services Gateways in a hot aisle/cold aisle ventilation environment. These kits convert the services gateway from side-to-side ventilation into front-to-back ventilation. The air deflectors contain no additional fans, so they require no additional electrical power. Air deflector kits are not available for the SRX3600 Services Gateway.
For more information about the hot aisle/cold aisle air deflector kits, send an e-mail to

.
The air deflector kits consist of four main components: two intake/exhaust boxes and two side plenums. The two intake/exhaust boxes are identical to each other, as are the side plenums.
The intake/exhaust boxes are installed above and below the services gateway to direct intake air from the air space in front of the services gateway into the side plenum mounted on the intake side of the device. The intake air plenum directs air into the services gateway, and the exhaust air plenum collects the exhaust air on the opposite side of the device.
The exhaust plenum directs the exhausted air into the intake/exhaust boxes above and below the unit, where it is expelled into the air space behind the services gateway.
The air deflector kit requires additional space around the services gateway, increasing its overall height and width as described in
