: Bottom Slot Installation
Instructions for installing an option card into one of the three bottom slots (1, 3, or 5):
- Safely power down the SecureSync unit and remove the top cover of the main chassis (housing). Save the screws.
Caution: NEVER install an option card from the rear of the unit, ALWAYS from the top, after removing the chassis cover.
- Remove the blank option card plate, or the existing option card in the slot. Save the screws. If a card is populating the slot above the bottom slot your option card is to be installed into, remove it temporarily.
- Insert the card into the bottom slot by carefully pressing its connector into the mainboard connector (see Figure below), and by lining up the screw holes on the card with the chassis.
- Using the supplied M3 screws, screw the board, and the option card plate into the chassis, applying a torque of 0.9 Nm/8.9 in-lbs.
Caution: Ensure that screw holes on the card are properly lined up and secured to the chassis before powering the unit up, otherwise damage to the equipment may result.
