I have heard different things about this, but does anyone have any experience with XMI000 wither shelf 4,20 or 24 XPEC error #0001 or FPEC error #0001? I am new to the M1 and any error is kind of annoying. We get these sometimes 15 times a day. I was told by one guy that it could be missing patch 03943. If I need that patch, I do know that I do not have it in the switch. What does it fix>? Thanks guys.
