Structure and supported library configurations

Supported library configurations

All libraries start with a Base Module. See Figure 1. For more capacity, up to fifteen Expansion Modules can be added as needed to support customer requirements. See Figure 2. The Expansion Modules are distributed above and below the Base Module.

The total maximum height of a fully expanded library depends on the library type. Older libraries had a maximum height of 21U. Newer Libraries can be expanded up to 48U. Refer to Figure 3. The first example is a one module library  1 , it consists of just the base module. The second is a 21U library  2 . The base module is fourth from the bottom, and is surrounded by six expansion modules. The maximum 21U configuration cannot be built in any other way. The third example is a full 48U library  3 . In this configuration, the base module is roughly in the middle with seven expansion modules above and eight below, fifteen expansion modules total. The maximum 48U configuration cannot be built any other way.
