ALPS ASCU AUTO DISABLE

YeungKinSan · ‎03-25-2008

Hi,

I alway get "..RX 4 consecutive UTS msgs from...- disabling ascu", which parameter control consecutive msgs count?

And How can i fix this problem?

It seems there are line problems to the ASCU (the CRC error checks). As a result of the CRC errors, the ASCU is taken down. I think this is a physical layer issue. Please check that.

Maybe is not physical layer issue. We have 30 ASCUs, normally is UP, but 3 to 4 days should get one DISABLE.
