Component Description

Component Description

This section provides the detailed illustration and description for each component.

System Subrack

The system subrack houses a midplane to provide reliable connections for interface modules and to distribute power and signals to inner modules.

Appearance

Figure 4-24 shows the appearance of a system subrack.
