I have an LU25 w/ 7000 controller.

I am getting
343-DMA Transfer Error 4 Memory Disk

I cannot figure this one out. I have swapped out the memory card. Ive reloaded the software without error. I have checked the fiber optic cables.
I still get this upon boot.

Anyone have any ideas?

thanks

What configuration of memory do you have? Do you have daughter expansion memory cards on the main memory board? Do you have more than one memory board in the rack? Have you tried moving the memory card to a different rack slot (you can do this, just make sure that the rack slot you move to has the same number of connectors; slots have 1 or 2 connectors depending on the rack configuration).

what user action caused this alarm?
Have you full Okuma software installation distributives for this machine?

it has the main memory card, and 2 mb1 cards. on the main memory card there is a daughter board screwed on to it. the machine was running fine. then it sat for a few months and now has this error. I do have all the original disk for it. I did reload them and they do reload completely just fine. its upon reboot that I get this error.
I just tried swiping the memory cards in different slots and same error.
I will monitor this all day today. thanks for any help
