Strategy for replacing FRUs for CTO, CMV, and GAV
Product definition
Dynamic Configure To Order (CTO)
This provides the ability for a customer to configure an IBM
®
or a Lenovo solution
from an eSite, and have this configuration sent to fulfillment, where it is built and
shipped directly to the customer. The machine label, Product Entitlement
Warehouse (PEW), eSupport, and the HMM will load these products as the 4-digit
MT and 3-digit model, where model = “CTO” (Example: 1829-CTO).
Custom Model Variant (CMV)
This is a unique configuration that has been negotiated between IBM or Lenovo
and the customer. A unique 4-digit MT and 3-digit model is provided to the
customer to place orders (Example: 1829-W15). A CMV is a special bid offering.
Therefore, it is NOT generally announced.
v The MTM portion of the machine label is the 4-digit MT and 3-digit model,
where model = “CTO” (Example: 1829-CTO). The PRODUCT ID portion of the
machine label is the 4-digit MT and 3-digit CMV model (Example: 1829-W15).
v The PEW record is the 4-digit MT and 3-digit model, where model = “CTO”
(Example: 1829-CTO).
v eSupport will show both the CTO and CMV machine type models (Example:
1829-CTO and 1829-W15 will be found on the eSupport site.)
v The HMM will have the 4-digit MT and 3-digit CTO model only (Example:
1829-CTO). Again, CMVs are custom models and are not found in the HMM.
General Announce Variant (GAV)
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 “CTO” (Example: 1829-F1U).
Also, PEW, eSupport, and the HMM will list these products under the same fixed
model number.
FRU identification for CTO, CMV, and GAV products
There are three information resources to identify which FRUs are used to support
CTO, CMV, and GAV products. These sources are PEW, eSupport, and the HMM.
Using PEW
v PEW is the primary source for identifying FRU part numbers and FRU
descriptions for the key commodities for CTO, CMV and GAV products at a MT
- serial number level. An example of key commodities are hard disk drives,
system boards, microprocessors, Liquid Crystal Displays (LCDs), and memory.
v Remember, all CTO and CMV products are loaded in PEW under the 4-digit MT
and 3-digit model, where model = “CTO” (Example: 1829-CTO). GAVs are
loaded in PEW under the 4-digit MT and 3-digit model, where model = a “fixed
part number”, not “CTO” (Example: 1829-F1U).
v PEW can be accessed at the following Web site:
http://www.lenovo.com/support/site.wss/document.do?lndocid=LOOK-WARNTY
Select Warranty lookup. Input the MT and the Serial number and the list of key
commodities will be returned in the PEW record under COMPONENT
INFORMATION.
