SGI Racks for Silicon Graphics Prism
The system is offered in two rack types: a short rack and a tall rack. The racks are
measured in standard rack units (U); one U is equal to 1.75 in. (4.45 cm). The short rack
is a 17U rack (see Figure 2-11). The tall rack is a 39U rack (see Figure 2-14).
Each component within the rack is identified by the lowest U number that it occupies.
For example, the top (XG2N) module shown in Figure 2-11 is described as being located
in U12.
