Brocade FastIron Ethernet Switch Software Upgrade Guide - Manual (Page 41)

NOTE
On ICX 6430 and ICX 6450 devices, you can use the same syntax as FCX devices. However, after
the copy operation is completed at the host, you do not get the command prompt back because the
device is synchronizing the image to flash. To ensure that you have successfully copied the file,
issue the show flash command. If the copy operation is not complete, the show flash command
output will show the partition (primary or secondary) as EMPTY.
4. Verify that the flash code has been successfully copied onto the device by using the show flash at
any level of the CLI.
5. Reboot the device using the reload or boot system command.
6. Verify that the new flash image is running on the device by using the show version command.
Software recovery
If the software upgrade or downgrade fails, the device might reboot continuously as shown in the
following CLI ouput:
bootdelay: ===
Booting image from Primary
Bad Magic Number
could not boot from primary, no valid image; trying to boot from secondary
Booting image from Secondary
Bad Magic Number
## Booting image at 01ffffc0 ...
Bad Magic Number
## Booting image at 01ffffc0 ...
Bad Magic Number
could not boot from secondary, no valid image; trying to boot from primary
Booting image from Primary

This section explains how to recover devices from image installation failure or deleted or corrupted flash
images.
NOTE
It is recommended that software recovery is performed under the supervision of a Brocade support
engineer.
Software recovery on FCX and ICX 6610 devices
NOTE
In practice, the TFTP server is also used as terminal server to see the CLI output.
1. Connect a console cable from console port to the terminal server.
2. Connect Ethernet cable from the management port (port located under the console port on the
device) to the TFTP server.
3. On the TFTP server, assign an IP address to the connected NIC. For example, 10.10.10.1 mask
255.255.255.0.
4. Reboot the device and go to the boot monitor mode by pressing "b ". For example:
BOOT INFO: RESET ACTIVE
master arbitrate : become primary arbitrator.
