Chassis Requirements - RECOMMENDED

To ensure the power supply can be easily integrated, the following features should be designed into a chassis intended to use a TFX12V power supply:

  • Chassis cutout (normally in the rear panel of the chassis) as shown in Figure 15-5.
  • EITHER a mounting bracket to interface with the forward mounting hole on the power supply OR a mounting tab as shown in Figure 15-6 to interface with the mounting slot on the bottom of the power supply.
