4.1Optional Chassis Mounting Features

STATUS

Optional

The optional top access mounting method fastens to the system chassis via three mounting holes; two on the exterior face and one with the tab on the interior face of the cage. There are also four rectangular cutouts on the bottom of the cage. These are intended to drop over the top of rectangular features in the bottom of the chassis. This will help position the cage and secure it laterally. The features in the chassis are shown below as a reference.

4.2Airflow Requirements

STATUS

Recommended

The power supply cooling, whether in the cage or the module, shall have a two-speed fan(s) and provide cooling to both the supply and the system. During low-speed fan operation, the power supply must not exceed a noise level of 43 dBa measured at one meter on all faces. At low fan speed, the power supply shall provide a minimum of 6 CFM. At high fan speed, the power supply shall provide a minimum of 9 CFM.
