Hello. M1000e chassis's CMC can be updated with the blades running. Note that when you have redundant CMC, it is recommended that you first update the Standby CMC, fail over to this CMC, update the now Standby. Finally, fail the CMC over again so the original Primary CMC.
Hello to everyone! I actually did a research about how to upgrade CMC on PowerEdge M1000e  I already know several methods from the manual device and this community. But my big question is, before to upgrade i need to turn off my Blade Servers? Or I can do it with the devices turned on?   thanks !
