My system is hanging on LED 4B27D410 during start-up. Can anyone tell me what it means? Thanks for your help.

translated that chinese post... all i could get is some gibberish about the CPU, so i replaced it... works like a champ now... this was an RS/6000 7044-170
FYI: the service guides contain most of what you might want to know - but have a very annoying habit of putting spaces and X’s in the reference codes.
i.e.
4B2xxx10 - Machine check - 0
1. Attempt to reboot the system in service mode to preserve the AIX error log. If the reboot fails, attempt to boot from the CD-ROM. If the reboot is successful, run diagnostics in problem determination mode to determine the cause of the failure. Otherwise, continue.
2. Go to MAP 1540: Minimum Configuration, Step 1540-21 on page 51.
Which I admit would have been of little use to you, but I just thought I'd pass on the principle.
The above was taken ( without consent ;0) ) from the 7044-170 service guide:
