Lenovo 3254ACU, Hardware Maintenance Manual, Page: 31 / 112

• 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).
• The PEW record is the 4-digit MT and 3-digit model, where model = “CTO” (example: 1829-CTO).
• eSupport will show both the CTO and CMV machine type models (example: 1829-CTO and 1829-W15 will
be found on the eSupport site.)
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 and eSupport will list these products under the same fixed model
number.
FRU identification for CTO, CMV, and GAV products
There are two information resources to identify which FRUs are used to support CTO, CMV, and GAV
products. These sources are PEW and eSupport.
Using PEW
• PEW is the primary source for identifying FRU part numbers and FRU descriptions for the key 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.
• 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).
• 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.
Using eSupport
For key commodities (examples - hard disk drive, system board, microprocessor, LCD, and memory)
eSupport can be used to view the warranty status of key commodities built in a particular machine serial (this
is the same record found in PEW). eSupport can be accessed at http://www.lenovo.com/support.
To view the warranty status of the key commodities on your computer, do the following:
1. Go to http://www.lenovo.com/support.
2. Click Warranty & Services .
3. Click Check Warranty Status .
4. On the Warranty Status Lookup page, click Parts Lookup .
5. Type your machine type and serial number, and then click Submit .
For the remaining FRUs (the complete list of FRUs at the MT model level)
eSupport also can be used to view the complete list of FRUs for a machine type and model.
To view the complete list of FRUs, do the following:
1. Go to http://www.lenovo.com/support.
2. Click Parts & Accessories .
