Installing a DVD Drive
The SC721TQ-250B2 supports one DVD drive. It can be installed only if the top mounted
fixed HDD is not used. It requires a mounting bracket rail (p/n MCP-220-81502-0N).
Installing a DVD Drive
1. Power down the system as described in Section 2.1 and remove the chassis cover as
described in Section 2.3.
2. Unlock the front bezel and swing it open.
3.
Remove the bracket for the top mounted fixed hard drive by removing the two screws.
4. Remove the two screws securing the EMI grid to the front of the chassis.
5.
Remove the EMI grid from inside the chassis, just behind the chassis front. If you will
later remove the DVD drive, save the EMI grid.
6. Remove the plastic DVD bay cover from the chassis front by carefully breaking it out.
