Note: Both I
2
C cable connectors are the same, enabling this cable to be
connected in either direction.
a. Connect one of the I
2
C cable connectors to the SCSI backplane.
b. Connect the other I
2
C cable connectors to the new 3-Pack SCSI
backplane. See the illustration in step 8 on page 69 for the cable connector
location.
10. Connect the end of the power-supply power cable that is labeled “HDD2” to
the new 3-Pack backplane. See the illustration in step 8 for the cable
connector location.
11. Slide the 3-Pack Ultra320 Hot-Swap Expansion option into the server until it
stops. Secure the 3-Pack Ultra320 Hot-Swap Expansion option to the server
with the four screws that come with it.
12. If you removed the air-baffle assembly, adapters, plastic dividers, and
adapter-support bracket in step 3 on page 68, reinstall them (see “Removing
and installing the adapter-support bracket” on page 54).
Note: Make sure that no cable is under the adapter-support bracket or
interferes with the center fans (connector J18).
13. Install additional internal hot-swap hard disk drives in the 3-Pack Ultra320
Hot-Swap Expansion option (see “Installing a hot-swap hard disk drive” on
page 74).
Note: The 3-Pack backplane sets the SCSI IDs for these hot-swap hard disk
drives. See “SCSI IDs” on page 107 for additional information.
14. If you have other options to install or remove, do so now; otherwise, go to
“Installing the server bezel and left-side cover (tower model)” on page 96 or
“Installing the server bezel and top cover (rack configuration)” on page 99.
