Install the Inner Rail Extensions
The ISS3500 chassis includes a set of inner rails in two sections: inner rails and inner rail
extensions. The inner rails are pre-attached to the chassis and do not interfere with normal use of
the chassis if you decide not to use a server rack. The inner rail extension is attached to the inner
rail to mount the chassis in the rack.
Install the Inner Rails
Perform the following steps to install the inner rails:
1. Place the inner rail extensions on the side of the chassis aligning the hooks of the chassis
with the rail extension holes. Make sure the extension faces "outward" just like the
pre-attached inner rail (see Figure 3-4).
2. Slide the extension toward the front of the chassis.
3. Secure the chassis with two screws as illustrated. Repeat steps for the other inner rail
extension.
