2.1 Hardware Identification
2.1.1 Module Identification
The CAI is identified by the three-letter “CAI” designation on the bezel and by two nameplate labels.
One nameplate label is large, similar to that shown in Figure 2-1, and located on the left side of the
module. A smaller label is located inside the bezel compartment. Both labels contain the CAI’s model
designation, part number/issue level, ROM version number, and serial number (S/N). The larger label
also lists the power requirements, and space is provided for information such as agency certifications.
