Bserebin,  Depending on the Lifecycle Controller version you will see either "User Settings" which should look like this { ユーザー設定 } or "USC Settings" which may look like this { USC設定 }. Select that and then look for "Language and Keyboard" which should resemble this { 言語とキーボード }. From there in the top drop down, highlight 英語 and in bottom select 米国. Click to save and exit {保存して終了 } and then reboot. click F10 and and see if the LC is coming through in english.  Let me know how it goes. 
Is it possible to change the default language for the LifeCycle Controller (Unified Server Configurator)? I'm doing some work on a Dell PowerEdge R410 (Japan), and the LifeCycle Controller's install is based on Japanese which is an issue since I can't read it. Any ideas how to change it to English?  Thanks, -Ben
