Strategy for replacing FRUs for CTO, special bid model, and standard
models
This topic provides information about the model types and FRU identification.
Product definition
This topic introduces different model types and how to identify each type.
Dynamic Configure To Order (CTO)
This model provides the ability for a customer to configure a Lenovo solution from a web site, and have this
configuration sent to fulfillment, where it is built and shipped directly to the customer. The machine label and
eSupport will load these products as the 4-character MT, 4-character model and 2-character country code.
The model is “CTO1” and the default country code is “WW” (example: 20AACTO1WW).
Special bid model
This model is a unique configuration that has been negotiated between Lenovo and the customer. A unique
MTM consists of a 4-character MT, a 4-character model, and a numeric 2-character country code is provided
to the customer to place orders (example: 20AA000955). The country code assigned is numeric and does
not designate a specific country or region. The custom model factsheet for the MTM indicates which country
the special bid MTM is set up for. Special bid offering is not generally announced.
Standard model
Standard models (fixed configuration) are announced and offered to all customers. The MTM portion of the
machine label consists of a 4-character MT, a 4-character model, and an alphabetic 2-character country
code. The country code assigned is alphabetic and represents a designated country or region (example:
20AA0009UK).
FRU identification
Use Lenovo eSupport to identify major FRUs, FRU part numbers, and FRU descriptions for a product at
