Brocade FC Switch FOS v7.2.0a WebTools Access in Windows Server 2012 R2 with IE 11

I got some errors (see at the end of the post) when setting up a brand new Brocade Fibre Channel switch running FOS v7.2.0a on a Windows Server 2012 R2 server with IE 11. The following instruction fixed the error.

• Install Oracle JRE 1.7.0 update 25 Windows x86 version
• According to its release note, FOS v7.2 is qualified and supported only with Oracle JRE 1.7.0 update 25.
• Install JRE Windows x86 version (32-bit), instead of Windows x64 version (64-bit) even Windows Server 2012 R2 is a 64-bit OS
• Launch “Java (32-bit)” in Control Panel
• Security tab, lower Security Level to Medium
• 
• (optional) Advanced tab, set “Perform certificate revocation checks on” to “Do not check”. This will speed up the “Verifying application” process if the server does not have the Internet access.
• 
• Launch Internet Explorer
• Click Tools, “Compatibility View settings” to add the Brocade switch IP address to the compatibility view list
• 
• 
• Enter the IP address of the Brocade switch in Internet Explorer
• 
• 
• 

The error messages I experienced and possible solutions

• “The version of Java plugin needed to run the application is not installed. The page from where the plugin can be downloaded will be opened in a new window.”
• Install the supported JRE version. see FOS release note for the supported JRE version
• Install the 32-bit version of JRE, instead of 64-bit version
• Verify Java Plug-In is enabled in IE
• Add the FC switch IP to IE’s compatibility list
• “Unable to launch the application” or “Unable to load resource: http://<switch-ip>/loc_res.jar
• Install the supported JRE version. See FOS release note for the supported JRE version
• “Application Blocked by Security Settings”
• Lower the Java Security to Medium in Java 1.7 Update 25. For the newer version of Java, add the FC switch URL to the Java Security Exception Site List.
