14. Touch the static-protective package that contains the optional SCSI backplane
to any unpainted metal surface on the server; then, remove the SCSI
backplane from the package and place it on a static-protective surface.
15. Locate the two alignment pins on the metal backplane support bracket. Attach
the optional SCSI backplane to the lower drive cage slots on the backplane
support bracket by matching the two alignment pins on the rear of the bracket
with the corresponding holes on the SCSI backplane. Use the six screws that
come with the option kit to secure the SCSI backplane to the backplane
support bracket.
16. Reinstall the backplane support bracket in the server. Tighten the captive
screw on top of the metal backplane support bracket by turning the screw
clockwise until it snaps into place. This secures the backplane support bracket
in the server.
Note: Make sure that no cables are under the backplane support bracket.
