I have Catalyst 6509 with 2 supervisor 720, one is Active and the other one is not presented to the switch. When I show the modules I get that the second supervisor is unknown and Not Applicable(See the file attached).
the second supervisor is booted on rommon.
I verify the version of the firmware and IOS (12.2(33)SXH), I have the same versions on the both supervisors.
Can you help please to resolve this issue.
