Troubleshooting Your System
7 If you have the non-RAID SAS controller daughter card, remove the hard drive and swap its drive bay
location with another hard drive that is functioning properly.
If the problem is resolved, reinstall the hard drive in the original bay. See "Installing a Hot-Plug Hard
Drive" on page 56.
If the hard drive functions properly in the original bay, the drive carrier could have intermittent
problems. Replace the hard-drive carrier. See "Getting Help" on page 147.
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 147.
8 Check 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 the System" on page 53.
c
Verify that the cable connections between SAS backplane(s) and the SAS daughter card are
correct. See "Cabling the SAS Backplane Boards" on page 99.
d
Verify that the SAS cables are securely seated in their connectors.
e
Verify that the power connectors on the SAS backplane(s) are securely seated in their connectors.
f
Close the system. See "Closing the System" on page 53.
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 147.
