+===== 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 bash>
+apt install minicom
+minicom -D /dev/ttyUSB0

+! when transfer finishes:
+unset BAUD
