This is an APC Communication Cable for Hitachi Thunder Storage. The data protection that Hitachi Data Systems' Thunder 9500 V Series family of storage products provides is now further enhanced through integration with an APC Smart-UPS. Upon detection of power loss, the APC Smart-UPS communicates with Thunder to initiate and complete a graceful shutdown of the Thunder 9500V. Upon shutdown the APC Smart-UPS will then go into "sleep" mode to conserve battery until utility power is restored. Once utility power has been restored to the APC Smart-UPS, the UPS will signal Thunder to bootup.
