problem with system monitor card in 61C

[rwarde]

Well here is the scenario and keep in mind that we have already spent three separate visits to fix this to no avail. The problem is that when the NT8D22 (system monitor) cards are seated and configured correctly they immediately knock out the ring generator cards in two separate modules in two separate columns. We tried replacing the ring generators, we tried replacing the IPE power cards, we looked at all the grounds, and opened up the back of the 61C and inspected the cabling and we are stumped.

When the system monitor cards are plugged in the system spits out these codes indicating an issue with the ring generator and that PFT has been switched, the only problem is that there is no power failure configured on this system.

XMI0001
XMI0016
XMI0001
XMI0016

Can someone offer some advice?

Is it an AC switch? I had an AC powered 61 with what I thought was a bad monitor card and it turned out I had a PDU in the pedestal going bad and had to replace that.

Thanks,

Are you getting PWR messages or XMI messages?

What are you getting during midnight routines?
Have you tried disconnecting the monitor from column 1 and see if column 0 stats clean?

I fought this one in a 4 column switch for a while until I discovered that someone had reprogrammed TTY 0 to 9600 baud...can't tell you how many monitor cards I tested before we discovered this by SLOWLY reading the card setup.

Thanks for the replies. Jaxuser you are corect. They were PWR0001 and PWR0016 codes. The issue was fixed, the problem was a defective CP card in Core 0. I split the system, replaced the card and put it back together and when I plugged the sysmon boards back in and connected them everything was good.
