System#

As shown, the system runs HP Pass−Thru module version 1.0.1.6. HP mentions that this version is not meant
to be shipped to customers and is not published on their website. Their Pass−Thru module vendor shipped a
few modules with this version in error. Once HP discovered the link flap issue, they released a patch which
resolves this issue. Version 1.0.1.6 was requested from HP in order to further test the issue, but HP does not
have the version.

Note: The reason why this issue is only apparent with Release 5.2, and not older releases, is that there might
be more tolerance with improper HP modules in older Nexus operating systems.

If customers open service requests with similar symptoms, check the HP Pass−Thru module firmware and
have them upgrade to version 1.0.7.0.
