Replacing a Peripheral Interposer Board

1Install the peripheral interposer board:

a Carefully lower the interposer board into the system, being careful to avoid damaging components on the face of the board. See Figure 3-32.

b Align the installation alignment slot on the bottom of the interposer board with the alignment pin on the bottom of the chassis.

c Slide the retention slots on the interposer board over the retention hooks on the chassis.

d Slide the board downward until the blue retention tab snaps into place.

2Connect the SATA, planar interface, and control panel cables to the back of the interposer board. See Figure 3-32.

3Connect the power cable to the top of the interposer board.

4Reconnect the SAS and backplane power cables to the back of the SAS backplane. See Figure 3-30 or Figure 3-31.

5Replace the cooling shroud assembly. See "Replacing the Cooling Shroud Assembly" on page 70.

6Replace the PEM. See "Replacing the PEM or PEM Shell" on page 76.

7Close the system. See "Closing the System" on page 66.

8Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
