Network interfaces down

[patrav20]

Hi,

I try to add a 6400-P24 to and existing stack of two 6400 and the network interface of the unit 3 stay with Oper Status Down. Everything seem to be ok but the ni interface stay down... I got this error message on the console : esmHandleNIBootUpFailure() NI 3, err 0

Thanks for your help...

Its possible whole the stack of all three? Have you checked the correct miniboot/uboot/fpga of all three devices?
