2: System Overview and Options
Both rack types are industry-standard 19-inch racks, and they support two types of
mounting rails (shelf rails or optional slide rails) that hold the modules within the rack.
For example, the base compute, XG2N, CPU expansion, and CMPX modules can use
shelf rails or optional slide-mounting rails (see Figure 2-12). The optional TP900 storage
modules always use shelf rails, which are two parallel L-shaped mounting rails within
the rack (see Figure 2-13).
