If the hard drive functioned properly in another bay but does not function in the original bay, the SAS backplane has a defective connector. See "Getting Help" on page 179.

8Check the cable connections inside the system:

a Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

b Open the system. See "Opening and Closing the System" on page 65.

c Verify that the cable connections between the SAS backplane and the controller card are correct. See "Installing a SAS Controller Card" on page 112.

d Verify that the data cables are securely seated in their connectors.

e Verify that the power connector on the SAS backplane is securely seated in its connector.

f Close the system. See "Opening and Closing the System" on page 65.

g Reconnect the system to the electrical outlet, and turn on the system and attached peripherals.

If the problem persists, see "Getting Help" on page 179.
