Firmware version v6.2.1 sumx and sy applications (for Smart-UPS and Symmetra single phase UPS models)
Note: You can check the NMC2's firmware version under About->Network in the web interface or on the top right upon logging into the command line interface.)
Users that utilize Chinese language option
The Chinese language option does not translate properly due to a language pack translation bug.
For users that wish to use the Chinese language option, a new Chinese-only language pack has been created for sumx and sy v6.2.1 applications. Note: Language packs are version and application specific. This means the sumx_621_zhCn.lpk language pack must be used with the v6.2.1 sumx application and the sy_621_zhCn.lpk language pack must be used with the v6.2.1 sy application. The .lpk language pack files are available for download at apc.com (http://www.apc.com/tools/download/index.cfm) and attached to this knowledge base for your convenience.
For instructions on how to upload/change language packs, please refer to knowledge base article ID FA156166. This replacement Chinese-only pack will need to be uploaded/changed by FTP or SCP rather than during a firmware upgrade.
