Note: Before you attach an expansion rack to a standard rack or another expansion rack, you must remove
the outriggers from the racks so that the racks fit together correctly.
To attach racks together in a suite, complete the following steps:
1. On the side of the standard rack cabinet where you are attaching the expansion rack, remove the side
cover. For more information, see "Removing and installing the upper side covers" on page 13.
2. Apply the strip of gasket that comes with the hardware kit to the outside front and rear vertical edges of
the expansion rack to prevent the two racks from rubbing against each other.
3. Insert an attachment pin that comes with the expansion rack through the top slot on the front of the
standard and expansion racks as shown in Figure 16. The slot is behind the top hinge.
4. Hold the attachment pin in place with the box wrench and use the hex wrench to tighten a screw on each
side of the attachment pin.
5. Install a second attachment pin in the slot near the bottom hinge of the rack.
6. Hold the attachment pin in place with the box wrench and use the hex wrench to tighten a screw on each
side of the attachment pin.
7. Repeat step 3 to step 6 to attach the back of the racks together with two attachment pins.
Repeat this procedure to attach additional expansion racks to the suite.
