3. Verify that the code has been successfully copied by entering the following command at any
level of the CLI.
show flash
The output will display the compressed boot ROM code size and the boot code version.
4. Upgrade the flash code as instructed in the following section.
Upgrading the flash code
To upgrade the flash code, perform the following steps.
1. Place the new flash code on a TFTP server to which the Brocade device has access.
2. Copy the flash code from the TFTP server into flash memory. To do so, use the copy command
at the Privileged EXEC level of the CLI.
copy tftp flash <ip-addr> <image-file-name> primary | secondary
You should see output similar to the following.

3. Verify that the flash code has been successfully copied by entering the following command at
any level of the CLI.
NOTE: For units in an IronStack, when upgrading from one major release to another (for
example, from software release 07.1.00 to 07.2.00), make sure that every unit has the same
code. If you reload the stack while units are running different code versions, the units will not
be able to communicate.
show flash
If the flash code version is correct, go to step 4, otherwise, go back to step 1.
4. Once you have completed the upgrade, you must reboot the device to complete the upgrade
process. Use one of the following commands:
reload (this command boots from the default boot source, which is the primary flash area
by default)
boot system flash primary | secondary
A confirmation step may occur after a boot system flash primary/secondary command is
entered and gives an administrator the opportunity to make last minute changes or corrections
before performing a reload. The example below shows the confirmation step.
FWS648POE Router# boot system flash primary
