1.7.3.5 Installing the Shelf
1. Select the location in the rack. Try to keep the chassis as low as possible to keep the
center of gravity low.
The maximum height that the chassis can be mounted, will be determined by the maxi-
mum height that the fork lift can raise the pallet.
2. Open the Installation kit and make sure that all of the parts are in the box. See
Figure 2,"Installation Kit Parts".
The chassis should sit in the rack with the spine side as close as possible to the door. This
leaves maximum room for the cable management system.

Do not remove any of the blocks or either of the lock-down bars at this time.
The chassis is on ball bearings and can roll easily. Be aware that the chassis can roll off
of the pallet. Should the chassis start to fall, move out of the way. The chassis can
cause grave bodily harm should it fall on or near you.
It is recommended to set the top of the shelf at U5. Try and keep the chassis as low as
possible. Set the shelf from U3 to U5.
Placing the shelf too low may make it impossible to tighten the shelf brackets, in
step 11.
The distance between the vertical supports must be between 65 cm(25.6") and 80
cm(31.5"). If the distance in your rack is different, move the vertical supports so that
one pair is ~10 cm(4in.) away from the door.
The side of the chassis with the spine units will sit flush with the vertical supports of
the rack. The side of the chassis with the QSFP connectors will sit at the edge of the
shelf closer to the center of the rack.
