I got the same Problem with my CRS326-24S+2Q+ and the QSFP+ Module (FS.COM)...every time when I Reboot or power cycle my Server witch uses thes 40G connection it does not come up. Eject module and reinsert...works - This is not a solution! I'm useing SWOS 2.13 And the Card in the Server is a HP 544+...
