Installing the System Board

1Transfer the processors and heat sinks to the new system board. See "Removing a Processor" on page 99 and "Installing a Processor" on page 101.

2Remove the memory modules and transfer them to the same locations on the new board. See "Removing Memory Modules" on page 97 and "Installing Memory Modules" on page 95.

3Transfer the riser board to the new system board. See "Removing the Riser Board" on page 81 and "Replacing the PEM or PEM Shell" on page 76.

4Install the new system board:

a Holding the system board by the heat sinks, lower the right side of the system board into the chassis.

b Slowly lower the left side of the system board into the chassis.

NOTE: Ensure that the power cables from the power distribution board do not impede the system board as you lower the system board into the chassis.

cSlightly lift up the front of the system board and maneuver the system board to the bottom of the chassis until it lays completely flat.

dEnsure that all retention hooks on the bottom of the chassis are inserted into the retention slots on the system board. See Figure 3-35.

ePush the system board toward the back of the chassis until the blue retention pin snaps into place.

5If applicable, transfer the internal USB key, SD card, and TOE/iSCSI key.

6Install the RAID battery compartment:

a Insert the two securing tabs on the battery compartment into the two securing slots on the side of the chassis. See Figure 3-34.

b Press down the battery compartment to secure it.

7Connect the cables in the order listed below (see Figure 6-1 and Figure 6-3 for the locations of the connectors on the system board and on the SAS backplane):

•The three power distribution cables

•SAS power cable SAS backplane power connector
