Mounting Options - RECOMMENDED

The TFX12V mechanical design provides two options for mounting in a system chassis. The unit can be mounted using one of the mounting holes on the front end (non-vented end) or a chassis feature can be designed to engage the slot provided in the bottom of the supply. In order to accommodate different system chassis layouts, the TFX12V power supply is also designed to mount in two orientations (fan left and fan right) as shown in Figure 15-4. A mounting hole and slot should be provided for each orientation as shown in Figure 15-2. Details of a suggested geometry for the mounting slot are shown in Figure 15-3.
