external cables as necessary to replace the device.

to disengage them from the drive backplane.
Disconnect the configuration, power, and SAS signal cables

Note: You can also choose to disconnect the cables after removing
the backplane, if that is easier for you.
Lift the backplane up slightly and pull it out the server.
