remove the hard disk cage before replacing the SCSI backplane.
Requirements

server has been switched off
–
power cords have been disconnected

all SCSI hard disk drives have been removed
Check if all hard disk drives are uniquely identified so that you can
reinsert them into their original bays.
Ê
Disconnect the power cable (1), the SCSI data cable (2), and the I

C
connector (3) from the SCSI backplane.
Ê
Remove the four screws (two at each side) that fasten the SCSI backplane
holder to the hard disk cage.
Ê
Take the SCSI backplane together with the holder out of the server. Be
carefully with the isolation foil.
Ê
Press down the rear side of the body-bound rivets which fasten the SCSI
backplane to the holder and lift the SCSI backplane from the holder.
Installation of the new SCSI backplane is performed in reverse order.
