Firmware Banks
The C360 has two firmware banks, Bank A and Bank B that contain the firmware necessary to
run the switch. Each bank is independent of the other and you may use them to store the same
or different versions of the firmware.
Sometimes it is desirable to upgrade to a new software version while retaining the option of
booting from the previous version. The following process copies the previous version from
memory Bank B to Bank A, and download the new version to Bank B. This process
accomplishes the following:
● prevents the device manager image-file from being downloaded into Bank A - by providing
a non-existent file name for the Device Manager file.
● preserves the old version in Bank A
● allows the user to boot from either Bank A or Bank B (in other words using either the old or
new software version)
Note:
Note:
In normal operation, the Device Manager file should be copied to Bank A, and the
new firmware version should be downloaded to Bank B. This process copies the
old software version to Bank A and the new firmware version to Bank B, and
allows the user to boot from either version via the set boot bank command.
To perform this process, using the following CLI command:
copy tftp SW_image <new_ver_file> EW_image dummy <TFTP_server_IP_addr>
<module_number>
Example:
copy tftp SW_image c:\versions\C360\c363t EW_image x 149.49.138.170 1
● Since file "x" doesn't exist the Device Manager image will not be downloaded.
