The JSA3800 appliance uses this mounting option as its default configuration. The rack
mounting kit includes two rack rail assemblies. Each assembly consists of an inner fixed
chassis rail that is secured to the server chassis and an outer fixed rack rail that is secured
to the rack.
To mount the JSA3800 appliance on a four-post rack:
Install the inner rail extensions (optional).

NOTE: The JSA3800 appliance includes a set of inner rails that are
preattached to the chassis. You can attach optional inner rail extensions
to stabilize the chassis within the rack.
a. Place the inner rail extensions on the side of the chassis such that the hooks on
the chassis clip securely into the rail extension holes.
b. Slide the extensions toward the front of the chassis.
c. Secure the rails with screws as shown in
