Replacing the 8x2.5-inch drive backplane with controller
expander
To install the 8x2.5-inch drive backplane with controller expander, complete the
following steps:
1.
Read the safety information that begins on page “Safety” on page vii and
“Installation guidelines” on page 33.
2. Touch the static-protective package that contains the drive backplane to any
unpainted surface on the outside of the server; then, grasp the backplane and
remove it from the package.
3. Make sure that you have attached the card with the short interposer cables
from the old backplane to this replacement backplane.
4. Align the tabs on the bottom of the drive backplane with the slots on the
bottom of the backplane cage.
5. Insert the drive backplane tabs into slots on the bottom of the backplane cage
and push the drive backplane forward into the retention latch (on top of the
backplane cage) until the backplane is locked in place.
Note: You can reconnect the cables to the drive backplane before installing the
backplane onto the cage or you can connect the cables after you install the
backplane, if that is easier for you.
6. Reconnect the interposer cables to the other backplane.
7. Reconnect the long SAS signal cables to the backplane and the system board
that you disconnected them from earlier.
