I'm searching for upgrade steps for Cisco 6840 Switch, i have searched everywhere but there isn't one available online?
i'm facing an issue with the current IOS 15.2(2)SY2 and as per Cisco bug track (CSCur96442), it iis recommended to upgrade the IOS, but I'm now able to locate any instructions on how to perform the upgrade process.
the upgrade procedure for the 6840 is the same as for the 6000/6500:
