5. To move the air divider:
You need to move the air divider, so you can access to the disk drive backplane board. The
divider is mounted to the power supply side wall using two tabs, which are inserted into slots in
the side wall.
a. Lift the air divider so the tabs clear the slots in the power supply housing
side wall.
b. Move the air divider away from the side wall, lift it up, and bend the cables,
so you can rotate the divider away from the backplane and set it in the PCIe
slot area.
The disk drive backplane sets on metal flanges and is secured by a spring-loaded lever.
6. Disconnect the ribbon data cable and the power cable at the bottom of the disk
backplane board.
See the illustration shown in step 7.
7. To release the spring-loaded lever, lift it upward.
