Testing and restoring firmware on switches
Typically, users downgrade firmware after briefly “test driving” a new (or old) version and then restoring the
original version of the firmware. Testing a new version of firmware in this manner ensures that you do not
compromise your existing firmware because the test drive version only occupies one partition on your
switch.
CAUTION: When you test drive new firmware make sure you have disabled all features that are not
supported by the original firmware before restoring to the original version.
To test a different firmware version on a switch:
1. Verify that the FTP 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 http://www.hp.com
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 as admin.
5. Enter the firmwareShow command to view the current firmware.
