Product Change Notice

Barcode label

Paper stickers attached to the exterior of items to display a code that, when scanned, reveals management information about components.

Item number

ID of an item. Huawei's item number ranges from 8 to 17 digits in length. It consists of letters, numerals, and other characters ("-" and "="). An item number is also known as a part number (PN).

Item revision

One item number may have a number of revisions. An item revision format consists of one letter and two digits.

When an item has internal changes that do not affect its function, only the numerical part of the revision number is upgraded, from A01 to A02, for example. Revision A01 and Revision A02 are interchangeable.

When item functions are changed, only the letter part in the revision number is upgraded, from A02 to B01, for example. Revision B01 can be used to replace revision A02 but the reverse is not true.

Doc version

Version of the drawing used during processing of mechanical parts and cables. After revision management is adopted, the drawing version information is no longer included in the barcode label.

Serial number

Serial number (SN) is the exclusive identifier of an item. The SN can help after-sales personnel identify the maintenance period.

Model

A string of letters and numerals to indicate a specific item.

RoHS

Environment protection information:

Y: The item is RoHS5 compliant. No lead (Pb) information is included.

Y1, Y3: The item is RoHS5 compliant and contains lead.

Y2: The item is RoHS5 compliant and is lead-free.

Country of origin

Country where the item is manufactured

Manufacturer identifier

Manufacturer information that Huawei applies for from the Electronic Data Interchange Forum for Companies with Interests in Computing and Electronics (EDIFICE). The manufacturer identifier of Huawei is LEHWT.

1D code

A 1D code contains the serial number of an item, compliant with ISO/IEC 15417 Code128, and provided for barcode scanning. 1D codes are retained for business continuity.

2D code

A 2D code normally contains the serial number, item number, item revision, and manufacturer identifier information. Some 2D codes do not contain manufacturer identifier information due to length limitations. 2D codes comply with the ISO16022 - Data Matrix standard and are provided for barcode scanning as an upgrade of the 1D code.

FRU

Field replaceable unit

E-label

Readable electronic label provided for active FRUs. An e-label contains the main information in the corresponding barcode label. Due to compatibility with historical revisions, the field names in e-labels may be inconsistent with those in the corresponding barcode labels.
