Just reading the "DS4243 ~ Installation and Service Guide" while creating my plan to install 3x DS42434 shelves into an empty 42U cab. I have always built racks from the bottom up, centre of gravity, etc but the shelf guide talks about top down stacks.
{Yes I do think I will be adding more shelves in the future}
What do you do when placings stacks into cabs?
1). Place the 'Top Shelf' in the bottom of the cab and add shelves to the 'bottom shelf' which is the physical top of the cab {Oz style...}
2). Start at the top of the cab and work your way down as described in the guide {Rack feet and cabs bolted together, why worry...}
3). Do not plan to hot add and place the bottom shelf in the bottom of the cab and then just move all the shelves up when required. (Does not happen often...)
4). Same as 3). but leave a 5U gap for a possible future extra shelf
Thanks for the help. Currently planning option 4 but thinking about 1...
