6�4�3 Thermal Management without Fan Tray
When installing the eLimiter+ without a fan tray, 3RU space is required for thermal management. Each shelf requires
a 1RU air space, 1 baffle tray and then an additional 1RU air space, see Figure 7.
Install the first converter shelf and then leave 1 RU of air space directly above the converter shelf. Install a baffle tray
above the air gap, and then leave 1RU of air space between the subsequent converter shelf.
Provide a minimum 3-inch air space between the floor and the bottom of the unit for ventilation.
