1 Adjust the length of the two assemblies (callout 1) to agree with the distance between the outer face
of the vertical rack posts.
The screws (callout 5) holding the assembly together may need to be loosened slightly to allow for
the adjustment. Retighten any loosened screws after the adjustment has been made.
2 Install the side of the assembly labeled "right front" (callout 2) on the front (cool air inlet) right rack
post.
Secure the assembly to both the front and rear posts, using rack appropriate screws or fasteners
that you supply.
Do not use the middle hole when securing the assembly to the rack post. The middle hole is used to
secure the adapter plate (previously installed on the chassis) to the assembly.
3 Repeat step 2 for the assembly labeled "left front."
