Virtual chassis Alcatel Lucent os 6900 with different firmware version

[Rlombardo]

Hello,

I have a problem with my two Alcatel Lucent os 6900 in a virtual chassis. I upgraded the firmware of them and after saving the configuration, they were both in the same version.
Then I tried to test redundancy and I removed the power cords from one of them. But when I put the power back on, the firmware of the slave downgraded and now they can't communicate.
I would like to know if there is a way to perform an upgrade of the slave ?
Thank you.

what was your issue?
Did you validate the software upgrade before you rebooted?
