NOTE:
6�4�2 Forced Air Cooling with LPS Fan Tray — Two and Three Shelves
Two and three shelves require a fan tray and two baffles to meet the specified cooling requirements for both CO and
OSP applications. Install the fan tray directly below either two or three converter shelves and a baffle tray below the
fan tray as shown below in Figure 14. In addition, install a baffle tray above the converter shelves.
Up to nine converter shelves can be managed by a single controller, provided each three contiguous shelves has fan
cooling.
