To install the 8x2.5-inch hot-swap drive backplane with controller expander, complete the following steps:
Step 1. Read the safety information and installation guidelines, see "Safety" on page v and "Installation
guidelines" on page 38.
Step 2. Turn off the server (see "Turning off the server" on page 23) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables from the server.
Step 3. Remove the top cover (see "Removing the server top cover" on page 40).
Step 4. Remove the fan cage assembly (see "Removing the fan cage assembly" on page 44).
Step 5. Remove the microprocessor and memory expansion tray (see "Removing the microprocessor and
memory expansion tray assembly" on page 292) or DIMM air baffle (see "Removing the DIMM air
baffle" on page 220), whichever one is installed.
Step 6. Open the SAS cable guide cover.
Step 7. If backplane filler panels are installed in the backplane bays in which you are installing the
backplane, remove the backplane filler panels.
Step 8. Connect the two 10x2-pin power connectors on the combination power/configuration cable to
the backplane power connectors on the system board. The power connector on the end of the
black cable (which might be labelled 1/3) connects to backplane connectors 3 on the system
board. The power connector on the end of the gray cable (which might be labelled 2/4) connects
to backplane connectors 4 on the system board. Connect the configuration connector on the
combination power/configuration cable to the configuration connector on the backplane. Connect
the other power connector on the combination power/configuration cable to the power connector
on the backplane.
Note: You can connect the cables to the backplane before you install the backplane onto the cage,
or you can connect the cables after you install the backplane, if that is easier for you.
