Connecting multiple racks with rack-to-rack attachment kit
You might need to connect multiple racks together. Use
the procedure in this section to perform this task.
About this task
This topic describes how to connect multiple racks to each other using a rack-to-rack attachment
kit. To do this, you will need the rack-to-rack attachment kit.
To
connect multiple racks with the rack-to-rack attachment kit, complete
the following steps:
If they are installed, remove the side panels from each
rack. Remove side panels only from the sides that will be attached
to each other by completing the following steps:
If the security kit is installed, slide the security bar to the unlocked position.
Pull down on the two panel-release tabs.
Pull the panel up and away from the rack chassis. This motion
will release the panel from the two lower J brackets.
Store the side panels.
Remove the two Z brackets and the two J brackets. These
brackets are used to hang the side panels.
Install the first two standoffs in the upper-left and lower-right
corners of the first rack as shown in Figure 1.

Position the racks together.
Align the standoff holes. You might need to adjust the
leveling feet to do this.
Install a screw and washer into all four positions, but
do not tighten.
After all racks are bolted together, level the racks.
Tighten all four screws.
Snap on the trim pieces that go between the front and rear of the racks.
Snap on the trim piece that goes on top and between the
racks.
Install rack filler panels to cover the open areas at the
front of the racks. All the gaps in the front of the rack must also
be sealed, including the gaps between equipment. This step ensures
that proper airflow within the rack is maintained.
Connect the cables that go between the racks.
If the racks are secured to a rack mounting plate, torque the four bolts securing the rack to
the rack mounting plate to 54 - 67 newton-meters (40 - 50 foot-pounds).
