I have a 6 module and a 12 module chassis. They are 5406 and 5412 R zl2. When I do show module detail, they are J9827A ( the management modules). When I do show run the top says JL9850A and JL9851A. I was looking to find the firmware and I do not see it for J9827A. If I type in the model (5406 or 5412) I get the right model, but it is for J9821A and J9822A.
Am I looking at the wrong product numbers? I know one model switch I have doesn't seem to have any firmware updates (JL693A) so maybe these chassis do not either?
