To install the simple-swap backplate, complete the following steps.
1. Insert the bottom tabs of the simple-swap backplate with the slots on the lower
lip of the drive cage.
2. Rotate the simple-swap backplate toward the drive cage until it locks in place
in the retaining tab of the spring-release latch on the drive cage.
3. Connect the combination signal/power cable the backplate (see “System-board
internal connectors” on page 11 for the location of the connectors).
4. Install the simple-swap hard disk drives that were removed from the hard disk

assembly” on page 128.
6. Press the power-supply cage release tab and rotate the power-supply cage
assembly into the chassis until it locks in place.
7. Return the power-supply cage handle to the locked position.
