SAS Backplane Removing the SAS Backplane CAUTION: Many repairs may only be done by a certified service technician. You should only perform troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that came with the product. 1 Turn off the system and attached peripherals, and disconnect the system from the electrical outlet. 2 Open the system. See "Opening the System" on page 78. CAUTION: To prevent damage to the drives and backplane, you must remove the hard drives from the system before removing the backplane. CAUTION: You must note the number of each hard drive and temporarily label them before removal so that you can replace them in the same locations. 3 Remove all hard drives. See "Removing a Hard-Drive Carrier" on page 84. 4 Disconnect the power cable from the SAS backplane. 5 Disconnect the SAS data cables from the backplane.
