Installing the 5U enclosure

The 5U84 enclosure is delivered without the disks installed. Due to the weight of the enclosure, install it into the
rack without DDICs installed, and remove the rear panel CRUs to lighten the enclosure weight.
The adjustment range of the railkit from the inside of the front post to the inside of the rear post is 660 mm – 840
mm. This range suits a one meter deep rack within Rack Specification IEC 60297.
1. To facilitate access, remove the door from the rack.
2. Ensure that the pre-assembled rails are at their shortest length (see also the reference label on the inside of the
rail).
