Internal 3.5" Hard Drives
The SC829U chassis supports four internal hot-swap 3.5" hard drives which are mounted
in individual hard drive trays contained in an internal chassis tray. After the chassis tray has
been installed into the chassis, the power can stay on when removing or installing the hard
drives from their individual trays.
Setting up the Internal Chassis Tray and Individual Trays
1. Power down the system and remove the chassis covers as described in Section 3.2.
2. Remove the two side screws securing the tray to the chassis and set them aside for
later use.
3. Lift the hard chassis tray up and out of the chassis.
