Connecting the Racks in a Suite (applies only to dual node 89.6 TB Configuration)
If you are installing a suite of racks, do the following:
1. If they are installed, remove the side panels from each rack. To remove the side panels:
a. Lift the two panel-release tabs up. See the following illustration for the two panel
release tab locations.
b. Pull the panel up and away from the rack chassis. This motion will release the panel
from the two
2. Lower J brackets. Store the side panels away from the work area.
3. Remove the two Z brackets and the two J brackets. These brackets are used to hang the
side panels. See the following illustration.
4. Stand facing the first rack and locate the right side.
5. Install a standoff in the upper-left corner and lower-right corner of the first rack. See the
following illustration for standoff placement locations.
6. Locate the second rack’s left side.
7. Install a standoff in the upper-left corner and lower-right corner of the second rack.
8. Attach the long foam strip as shown in the following illustration. Position the racks together.
9. Align the standoff holes. To align the standoff holes, you may have to adjust the leveling
feet.
10. Install a screw and washer in all four standoff hole positions, as shown in the following
illustration, but do not tighten. After the racks are bolted together, level the racks.
11. Tighten the four screws in the standoff holes.
12. Install the trim pieces that fit between the front and back racks.
13. Install the trim piece that fits on top and between the racks.
14. Install rack filler panels above and below the installed system drawers. The filler panels
cover and seal the open areas at the front of the rack(s).
Note: All open areas located in the front of the rack must also be sealed to ensure that
proper airflow within the rack is maintained.
15. Connect the cables that go between the racks.
