There are side airflow devices other than the Cisco models noted for AR7715 and AR7725 that require a duct kit.
All models and serial ranges.
Customers may want to use a side airflow duct kit with equipment it was not specifically designed for.
The AR7715 and AR7725 Side Air Flow Duct Kits are designed specifically for use with Cisco's side airflow switches.
AR7715 is designed to be used with Catalyst 6509, 6509E, 6513 and the MDS 9509 and 9513 Multilayer Directors.
AR7725 is designed to be used with Nexus 7009.
In general, when recommending a side airflow duct kit for equipment other than the Cisco products listed above we recommend using AR7725. The AR7725 is not as tall as AR7715 and it does not have a mounting rail required for the equipment, as the AR7715 does. To insure proper operation the airflow path should be similar to the Cisco models with similar chassis dimensions: 14U x 17.3" W x 24" D. Installing equipment that's not as tall or deep may result in the need of foam and/or duct tape to close off open spaces between the equipment and the duct.
The AR7715 can also be used with other Cisco 6500 series (such as a 6506) and 9500 series switches, but all components of the kit will not be used. The rear baffle connecting the top and bottom duct cannot be installed without field modification, because the other switches in this family are smaller. This is not a concern, since the smaller switches also have significantly lower airflow requirements. The top and bottom duct alone will supply the smaller switches with sufficient airflow. The height of the AR7715 is adjustable from 24.49" to 33.35".
