To install the 4x2.5-inch hot-swap drive backplane, 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 bay in which you are installing the
backplane, remove the backplane filler panels.
Step 8. Connect the combination power/configuration cable end to the power and configuration connectors
on the drive backplane; then, connect the power connector on the other end of the cable to the
backplane power connector on the system board. See the following cabling illustration.
Note: You can connect the cables to the drive 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.
