Firmware updates
To update firmware, use the HP BladeSystem c-Class Virtual Connect Support Utility v1.7.0. For more
information on updating the firmware, see the HP BladeSystem c-Class Virtual Connect Support Utility
documentation on the Installing tab of the HP BladeSystem Technical Resources website
( http://www.hp.com/go/bladesystem/documentation ).
Virtual Connect v3.70/3.75 does not support the HP 1/10Gb Virtual Connect Ethernet Module or the HP
1/10Gb-F Virtual Connect Ethernet Module. If your domain contains these modules, you cannot update to
VC v3.70/3.75.
To help ensure proper operation, clear the browser cache and reload the browser after firmware updates.
The firmware downgrade process has changed with VC v3.70/3.75 and VCSU v1.7.0. The following table
describes the circumstances under downgrading VC firmware requires deletion of the domain.

rollback
Domain deletion is not required when a firmware downgrade is performed to a firmware version that existed
prior to the firmware upgrade. However, if no previous firmware upgrade has been performed,
downgrading without domain deletion is not allowed. When attempting a firmware downgrade, consider
the following:
• Multiple, consecutive firmware downgrades are not supported.
• A same version upgrade does not prevent a future downgrade if you decide to downgrade to the
previous version in the future.
• You can perform a firmware downgrade only to a version that was installed on the primary VC module
prior to the upgrade.
• The VCM configuration, module types, and cabling configuration must be the same before and after the
upgrade.
• The VCM credentials must be the same before and after the upgrade.
