4.1 Optional 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.
