Removing a 2.5-inch disk drive backplane
To remove a 2.5-inch hard disk drive backplane, complete the following steps.
1. Read the safety information that begins on page vii and “Handling
static-sensitive devices” on page 151.
2. Turn off the server and peripheral devices, and disconnect the power cords
and all external cables.
3. Unlock and remove the left-side cover (see “Removing the left-side cover” on
page 181).
4. Open the bezel by pressing the button on the left edge of the bezel, and rotate
the left side of the bezel away from the server.
5. Remove the hot-swap hard disk drives (see “Removing a 2.5-inch hot-swap
hard disk drive” on page 186).
6. Remove the power supply or power supplies from the power-supply cage (see
“Removing a hot-swap power supply” on page 273).
7. Rotate the power-supply cage to its open position (see “Opening the
power-supply cage” on page 154).
8. Remove the air baffle (see “Removing the air baffle” on page 212).
9. Remove the fan cage assembly (see “Removing the fan cage assembly” on
page 243).
10. Note where the power, signal, and configuration cables are connected to the
2.5-inch hard disk drive backplane; then, disconnect them (see “Hard disk
drive backplane connectors” on page 20).
11. Lift the retention latches that hold the backplane in place; then, grasp the top
edge of the backplane and rotate it toward the rear of the server. When the
backplane is clear of the drive-cage retention tabs, remove it from the server.
