To decrease the weight and make the chassis easier to install in a rack, remove
1.3
components from the chassis. Make a note of each component location so that
the component can be reinstalled in the same location. Press on the colored
latch and pull on the handles to remove the components. You can also remove
the shelves from the chassis to reduce the weight further.

If you have an adjustable rack, set the distance between the front and rear
EIA flanges to 719 mm (28.3 inches) outside to outside.
• Make sure that there is sufficient room in front of the front EIA flange to
provide minimum bezel clearance of 50 mm (1.97 inches).
Remove the rack door, if one is installed on the rack.
2.1
Pull the chassis rail forward and insert the posts on the front of the chassis rail into the
2.5
holes on the front EIA flange until it snaps into place. Repeat steps 2.4 and
2.5 for the right chassis rail.
Note:
1. Make sure that the bottom edge of the chassis rail is aligned with the bottom U that
you want the chassis to rest on.
2. If you misalign the chassis rail, press the locking hooks release or squeeze the locking hooks
on the chassis rail, slide the posts out of the holes, and try again.
