(Example: 1829-CTO). The PRODUCT ID portion of the machine label is the 4-digit MT and 3-digit CMV
model (Example: 1829-W15).

This is a standard model (fixed configuration). GAVs are announced and offered to all customers. The MTM
portion of the machine label is a 4-digit MT and 3-digit model, where model = a "fixed part number", not

FRU identification

Lenovo eSupport is the information resource used to identify which FRUs are used to support CTO, CMV,
and GAV products.
Using eSupport

commodities for CTO, CMV, and GAV products at an MT - serial number level. An example of key
commodities are hard disk drives, system boards, microprocessors, liquid crystal displays (LCDs), and
memory modules.
• All CTO and CMV products are loaded under the 4-digit MT and 3-digit model, where model = a "fixed
part number", not "CTO" (Example: 1829-F1U).
