4. Disconnect the two power cables from connectors PWR_CONN and 12V on the system board.
5. Remove the cooling shroud. See Removing the Cooling Shroud .
6. If the system has cabled SAS drives or SATA drives, note the relative location of the interface cable connections between the system board and the
drives, so you can reconnect them in the proper sequence.
7. Disconnect the SAS or SATA interface cable(s) connected to the system board or optional hard-drive controller card.
8. Disconnect the power cable(s) connected to the hard drives in the drive bay, or to the optional SAS backplane.
9. Remove the screws securing the drive bay and remove the bay from the system.

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system.
Before performing any procedure, see your Product Information Guide for complete information about safety precautions, working inside the
computer, and protecting against electrostatic discharge.
CAUTION: The processor heat sink can get hot during operation. To avoid burns, ensure that the system has sufficient time to cool before
removing the system board.
