K. The minimum horizontal opening of the inside of the rack at the front and rear
EIA flanges is 450 mm.
L. The minimum width between the required internal structure to the rack to
mount rail kits is 475 mm (481 mm within 50 mm of the front and rear EIA
flanges).
M. Mounts use 7.1 mm round or 9.5 mm square hole racks. Tapped hole racks
with standard rail kit are not supported.
N. NeXtScale System data and management cables attach to the front of the
node (chassis). Cable routing space must be provided at the front of the rack,
inside or outside the rack. Cable space (N) should from the bottom to the top
of the rack and be approximately 25 x 75 mm in size. Some cable
configurations might require more cable routing space.
We suggest installing the chassis 1 or 2 rack units from the bottom to allow space
for cables and the power line cords to exit the rack without blocking service
access to the chassis.
Shipping the chassis
IBM supports shipping the IBM NeXtScale n1200 Enclosure in an IBM 42U
1100mm Enterprise V2 Dynamic Rack if the shipping brackets that are supplied
with the chassis are installed. Shipping the chassis in any other rack is at your
discretion.
When it is installed in a rack and moved or shipped from one location to another,
it is necessary that the NeXtScale System shipping brackets are reattached. For
more information, see the documentation that is included with the chassis for the
installation of the shipping brackets.
