v For more information about connecting the SAS signal cables to the drive
backplane, see “Connecting the SAS cables” on page 61).
v The right-angle SAS signal cables that come with the backplane only connect to
the SAS signal cable connectors on the system board.
To install the 4x2.5-inch hot-swap drive backplane, complete the following steps:
1. Read the safety information that begins on page “Safety” on page vii and
“Installation guidelines” on page 33.
2. Turn off the server (see “Turning off the server” on page 21) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external
cables from the server.
3. Remove the top cover (see “Removing the server top cover” on page 36).
4. Remove the fan cage assembly (see “Removing the fan cage assembly” on
page 40).
5. Remove the microprocessor and memory expansion tray (see “Removing the
microprocessor and memory expansion tray assembly” on page 278) or DIMM
air baffle (see “Removing the DIMM air baffle” on page 210), whichever one is
installed.
6. Open the SAS cable guide cover.
7. If backplane filler panels are installed in the backplane bay in which you are
installing the backplane, remove the backplane filler panels.
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.
