6250 firmware update - Permission Exception

[luisepbueno]

I'm currently running firmware version 6.6.1.679.R01. I'm trying to update to a newer version, but the switch reboots a few seconds after I started sending files.

When the file transfer is about 2.5MB, the switch displays the following message:

Code: Select all

"MON MAR 07 16:12:22 : SYSTEM (75) info message:
+++ PEX 0 ERR. Non-Fatal Error Detected"

After the message is repeated a few times, the output below is shown and the switch reboots with running configuration as certified (the working is corrupted).

Code: Select all

I used two different switches with FTP and SFTP. Both shows the same behaviour.

After the switch reboots, I try to recover the working dir with "copy certified working" but the switch reboots again. That's why I thought it could be a problem with the flash memory, but when I try to copy the files from certified to working in miniboot, there is no problem.

Does anyone know what could cause this?

Hi,
you should try to recover the switches via USB from miniboot (alternate via z-modem). There are some posts here - you can also search in forum for OS6450.
