I bent 3 pins on universal slot 5 when installing a IST-8. I know should've been careful. Anyhow, No serial ports are working so I cannot log in and the serial integration is down. I took the cable off so at least a DID call to extension would go to the mailbox instead of box 800.

I picked up a new Maux II hoping the serial ports would work on it, and it didn't.

Is it the cpu/services board or the backplane that is fried?

Thanks.
