I did try to reload the switch from Secondary Partition. ..No-Go as the switch goes back to the same state.

Boot PROM password has not been set.

Noticed the OSLoader to have entry ATA() instead of MEM(). Why is it displaying ATA() instead of MEM()?

OSLoader=ATA()0x3c9bf;ATA()0xb9700

Has the CF gone bad?

Is switch replacement only possible solution or do we have any alternative?

Please advise

Thanks

If the switch is under mainatenance, i would open a call by Brocade.
