ISE I/O kernel error

[zacakg]

Hello,

When I run show tech | grep I/O command, I receive the belowed output. Is it safe to upgrade ISE?

What made you decide to look in show tech for if you should upgrade or not?  Do you have a TAC case open?  What verison?

Hi ahollifield,

We are planning to upgrade. I just want to make sure I/O speeds meet the requirements. @Mark Elsen's reply works for our case.
