SECTION 3.2: PARTS INFORMATION
This section contains reference designation lists that provide descriptive and provisioning information
for all electrical and mechanical parts that have an assigned reference designation and form a part of
the subject equipment.
Topics in this section include:
 Family Tree
 How to Locate Information About a Specific Part
 Column Content on page 3.2.2
Family Tree
A family tree is included in this section for each of the three low power VX model classes:
 VX150/VX300/VX600 - see Figure 3.2.1 on page 3.2.4
 VX1 - see Figure 3.2.2 on page 3.2.5
 VX1.5/VX2 - see Figure 3.2.3 on page 3.2.6
The family tree is based on the descending order of the reference designation hierarchy. Included are
assemblies that have a Nautel configuration control number (e.g., A2, part number NAPI189), non-
repairable third-party items (e.g., U2, part number UG130), and Nautel-modified third-party items (e.g.,
U4, part number 235-5910).
How to Locate Information About a Specific Part
To locate the information for a specific part, the assigned reference designation for the part must be
known. In addition, the Nautel nomenclature (e.g., NAPA40A) assigned to the assembly containing the
part or the full reference designation, including the reference designation of all higher assemblies, must
be known.
