Black KVM Screen on C-Series Server

After an upgrade from 1.2(1b) to 1.3(2d), some C210 servers may experience a black KVM screen after the memory test/Cisco splash screen.  POST of PCI devices/onboard NICs will not be viewable.  You can break into these options by connecting up a physical monitor to the server.

In order to workaround this issue, the PC's Java cache must be cleared.
Steps to clear the Java cache can be found at the following link: http://www.java.com/en/download/help/plugin_cache.xml

The defect that addresses this issue is: CSCtl93037 - vKVM is blank after updating the CIMC FW from AP to BP.
