To install a SAS/SATA 8 Pac HDD option, complete the following steps:

1. Read the safety information that begins on Safety and Installation guidelines.
2. Turn off the server and peripheral devices and disconnect the power cords and all external cables, if necessary.
3. Remove the cover (see Removing the cover).
4. Remove the two 4-drive filler panels that are to the right of drive bay 8, beneath the IDs 8 - 15 on the front bezel.
   Figure 1. Filler panels
   
   
5. To obtain more working room, remove fans 2 and 3 (see Removing a hot-swap fan).
6. Pull the hard disk drives or fillers out of the server slightly to disengage them from the backplanes. For more information, (see Removing a hot-swap hard disk drive).
7. Disconnect the SAS signal cables from the system board. Leave the other end of the SAS signal cables connected to the hard disk drive backplanes.
8. Remove hard disk drive backplane 1 from the server.

   1. From backplane 1, disconnect the following cables in the order listed:
      • Power cable 1
      • SAS signal cable 2
      • Configuration cable 3
   2. Lift backplane 1 out of the server by pulling it toward the rear of the server and then lifting it up.
9. Install the new backplane in slot 2:
   1. Connect two SAS signal cables (610 mm) to new backplane 2. The new backplane comes with the option kit.
   2. Connect the configuration cable to backplane 2.
   3. Screw the SEARAY cable to backplane 2 as shown in the following illustration and connect two SAS signal cables to backplane 1.

   4. Connect the configuration cable and the power cable back to backplane 1.
   5. Angle the new backplane and place the bottom edge into the slots for backplane 2 on the chassis next to the optical drive.

   6. Angle the backplane and place the bottom edge into the slots for backplane 1 on the chassis.
   7. Rotate the backplane upright so that the bracket goes underneath the latch and tabs on the chassis and is engaged into the slots on the backplane bracket.
10. Connect the loose end of the SAS signal cables (610 mm) to the system board. Route the cable underneath the cable retention features on the baffle. See the illustration.

13. If you removed any fans, install them.
14. Insert the hard disk drives and the fillers the rest of the way into the bays.

If you have other devices to install or remove, do so now. Otherwise, go to Completing the installation.
