Digest: The H805ADPD, H805VDMF, H805VDRD, and H80ASHLM boards of MA5600T
product need to be upgraded because their DDR1 memories are changed. Such a change is for
customers using these boards.
1.Product Engineering Code Change
1) Change Scope: The sites with H805ADPD,H805VDMF,H805VDRD,H80ASHLM boards
2) Change relation : The new boards are produced with new DDR1 memories, all the function
and performance are the same ,the BOM is the same too. The boards current used in sites
won’t be effected.
3) Change finish date :
H805ADPD:2010-12-31.Huawei will use old DDR1 memories to product board to deliver before
2010-12-31, and please push the related office to upgrade the corresponding IO board package files
and software patches as soon as possible .We will deliver the new board after 2010-12-31, and
won’t be permitted to deliver the boards if the office didn’t upgrade the corresponding patches.
H805VDMF, H805VDRD, H80ASHLM:2010-9-30, please push the related office to upgrade
the corresponding IO board package files and software patches as soon as possible.
3. Spare part Strategy
The new board as spare part
Impact and Risk
Functions and performances of the upgraded boards are not affected if the corresponding IO
board package files and software patches were not upgraded
H805ADPD:Proved by test ,the abnormal rate arrived about 30% if the board without
corresponding IO board package files, exceed normal .
H805VDMF,H805VDRD,H80ASHLM:Proved by test, the abnormal rate didn’t increase,
but it also exist the same risk as H805ADPD board.
Measures and Solutions
The related office which used these kinds new boards or will switch to theses kinds new
boards ,please upgrade to the corresponding IO board package files and software patches ,
as listed in the following table.
