We have a M1000e running, and I recently installed 2x FC8PT modules (8Gbit FC Passthrough).
They were both mounted in the slots C1 and C2. The bottom LEDs indiace that all is OK; green and blue LED is On.
I also installed a Qlogic QLM2572 card in a M610 blade, and installed necessary drivers etc. The cards were detected, all good so far. I mounted a new multimode LC cable from the PT module to our FC switch.
But no link?
There is no light in the PT port - and the LED lights is both flashing. The manual says that two flashing LEDs means firmware fault. Ok, no panic so far :)
I updated CMC firmware, and M610 bios. I also downloaded latest firmware for the Qlogic card, and updated it. But still, the lights are blinking, and no link.
