Testing and restoring firmware on switches

Typically, users downgrade firmware after briefly evaluating a newer (or older) version and then restore
the original version of the firmware. Testing a new version of firmware in this manner ensures that you
do not replace existing firmware because the evaluated version occupies only one partition on the
switch.

ATTENTION

When you evaluate new firmware, make sure you disable all features that are not supported by the
original firmware before restoring to the original version.

Testing a different firmware version on a switch

1.

Verify that the FTP, SFTP, or SSH server is running on the host server and that you have a user ID
on that server.

2.

Obtain the firmware file from the Brocade website at

http://www.brocade.com

or the switch support

provider and store the file on the FTP or SSH server.

3.

Unpack the compressed files preserving directory structures.

The firmware is in the form of RPM packages with names defined in a .plist file that contains
specific firmware information and the names of packages of the firmware to be downloaded.

4.

Connect to the switch and log in using an account with admin permissions.

5.

Enter the firmwareShow command to view the current firmware.

6.

Enter the firmwareDownload -s command to update the firmware, and respond to the prompts.
