The cable-management brackets are attached to the chassis after you install the chassis rack-mount brackets
on the chassis and mount the chassis in the rack
Note
Step 1 Locate the threaded holes on the side of the chassis. Ensure that you hold the front rack-mount bracket with the ear and
holes facing outward and towards the front of the chassis. The following figure shows where to attach the front rack-mount
brackets to the controller.
Step 2 Position the front rack-mount bracket top hole with the chassis, first top hole behind the side vent holes.
Step 3 Insert and tighten the black screws on one side.
Step 4 Repeat Step 1 to Step 3 on the other side of the chassis. Use black screws to secure the rack-mount brackets to the chassis.
Mounting the Controller in the Rack
After installing the rack-mount brackets on the chassis, mount the chassis by securing the rack-mount brackets
to two posts or mounting strips in the rack using the screws provided. Because the rack-mount brackets support
the weight of the entire chassis, ensure that you use all the screws to fasten the two rack-mount brackets to
the rack posts.
Two-Post Rack Installation
Before you begin
The controller can be installed on a two-post rack, either 19 inch or 23 inch. We recommend that you allow
at least 1 or 2 inches (2.54 or 5.08 cm) of vertical clearance between the controller and any equipment directly
above and below it.
Step 1 On the chassis, ensure that all the screw fasteners on the installed components are securely tightened.
Step 2 Make sure that your path to the rack is unobstructed. If the rack is on wheels, ensure that the brakes are engaged or that
the rack is otherwise stabilized
Step 3 (Optional) Install a shelf in the rack to support the controller. If you use a shelf, it helps support the chassis while you
secure it to the rack.
If you are using a shelf, place the chassis on the shelf and slightly raise the front of the chassis to align the
mounting bracket holes with the rack post holes while allowing the bottom of the chassis to rest on the shelf.
Note
Step 4 With two people, lift the chassis into position between the rack posts.
Step 5 Align the mounting bracket holes with the rack post holes and attach the chassis to the rack.
Step 6 Position the chassis until the rack-mounting flanges are flush against the mounting rails on the rack.
To allow space to attach the cable-management brackets to the chassis in the rack easily, use the rack-mount
bracket ear holes mentioned in Steps 7 and 8.
Tip
Step 7 Hold the chassis in position against the mounting rails in the equipment rack and follow these steps:
