12. Disconnect the internal SAS cables attached to the system board (if necessary. See
Figure 6-47
.
CAUTION:
When disconnecting the SAS cables, note the labeling on the cables. When
reconnecting these cables, match each cable with the appropriate socket on the SAS core I/O
card. If the cables are mismatched, the server may not reboot. Both the cables and the sockets
are clearly marked with the correct channel.
NOTE:
The cables connect directly to the system board for a non-RAID configuration, and
connect to the Smart Array P400 controller board for a RAID configuration.
13. Remove the Trusted Platform module (if necessary). See
“Removing the TPM” (page 189)
.
14. Disconnect the power cable that attaches the Smart Array P400 controller board to the battery
on the airflow guide (if necessary).
15. Remove the Smart Array P400 controller backplane and the PCIe expansion card (if
necessary).
16. Remove the I/O fan carrier. See
“Removing the I/O Fan Carrier Assembly” (page 165)
.
17. Disconnect the cables that attach to the system board (1). See
Figure 6-47
.
18. Pull up on the post in the center of the system board to unlock it from the server chassis.
See
Figure 6-47
.
19. Shuttle the system board toward the front of the server until the board keyways clear the
server guide pins. Tilt the system board toward the rear of the server and lift it out at an
angle from the server to remove it.
