Dear Kenneth R.,
Thank you for your reply.
Is it possible to do firmware update via chassis on the switch while it is boot loop and the switch status is unmanageable in the management module ?
Or Do I have to do firmware update on the switch itself ? But I don't know how to extract switch firmware from chasiis firmware and I don't know how to do the firmware update on the switch, because there is no manual explaining to do firmware update on the switch (I search on the google, It may related with XMODEM),
FYI my customer chassis is MFSYS35 and my backup unit chassis in my office is MFSYS25V1.
I put customer's switch module in my chassis and the problem is the same.
my MFSYS25V1 firmware have the latest version, 6.10, but the chassis can not update the switch firmware.
best regards
