====== FW Update ======

Backup current FW
<code bash>
dir flash:
copy flash:/c3560-ipbasek9-mz.122-55.SE12.bin tftp://192.168.28.199/c3560-ipbasek9-mz.122-55.SE12.bin
</code>

===== upgrade from tar archive =====
This is recommend method. It will install all files (i.e. webui pages) from tar archive (not only firmware binary).

<code bash>
enable
! make free space 
delete flash:/c3560-ipbasek9-mz.150-2.SE11.bin
archive download-sw /overwrite tftp://192.168.28.199/c3560-ipbasek9-tar.150-2.SE11.tar
reload
</code>


===== manual upgrade from bin =====
Upload new firmware:
<code bash>
! check free space:
show flash
dir flash:
copy tftp://192.168.28.199/c3560-ipbasek9-mz.150-2.SE11.bin flash:/c3560-ipbasek9-mz.150-2.SE11.bin

conf t
no boot
boot system flash:c3560-ipbasek9-mz.150-2.SE11.bin
exit
wr mem
reload

</code>


===== Boot without firmware =====

Idea is to upload missing firmware file using console cable and XModem transer.
<code bash>
apt install minicom
minicom -D /dev/ttyUSB0
</code>

<code bash>
! switch terminal to faster spped
set BAUD 115200

copy xmodem:c3560-ipbasek9-mz.150-2.SE11.bin flash:c3560-ipbasek9-mz.150-2.SE11.bin

! CTRL+A+Z and choose send file from minicom menu
! when transfer finishes:

unset BAUD

boot flash:c3560-ipbasek9-mz.150-2.SE11.bin
