Damage due to servicing that is not authorized by Dell is not covered by your warranty. Read and follow the safety instructions that are shipped with your product.

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 insert them in the same locations.

  3. Remove all hard drives.
  4. Disconnect the SAS/SATA data, signal, and power cables from the backplane.
