7. Disconnect the backplane or back plate cables:
• If the server is a hot-swap model, disconnect the SAS/SATA controller signal cable from the backplane.
Note: You might want to disconnect the cable from the SAS/SATA controller rst, or remove the
SAS/SATA controller from its connector, to make it easier to disconnect the cable from the backplane
or back plate.
• If the server is a simple-swap mode that contains a standard SATA back plate, disconnect the SATA
cable from the system board.
• If the server is a simple-swap model that contains a SATA RAID back plate, disconnect the SAS signal
cable from the SAS/SATA controller.
8. If you are instructed to return the backplane or back plate, follow all packaging instructions, and use any
packaging materials for shipping that are supplied to you.
