GE Signa Profile 4B _TCU problem

July 19, 2019 10:40

Hello.
I reinstalled SW on Signa Profile and Now I have error
message : Temperature Controller Communication error detected. Communication time out--Error:2240982/
Before SW reinstallation there was no problem with TCU. It is working and shows target temperature 32.5 now.
Can someone help me with this case?

I noticed one message during Solaris boot--ifconfig: SIOCGFFLAGS: vd0: no such interface! Does this message refer to my problem?

I don't think so. hme0 and vd0 are network interface devices.

Your Bit3 cards are fine on Sun PC and TPS chassis.

Dear Steven, how to check, is there problem with Bit3 or not?
I am not good at Solaris systems. Can you recommend something?In other side I am sure that TCU error appeared after SW reinstallation!

I have encountered this problem before,and try many thing like change TCU, I am lucky because has other same type MRI test, first time We exchange the Host and found the Bad Host will be your problem, so we focus to Host, and change new fiber card.

You must to buy a new fiber card. Good Luck
