The error code remains on the Operator Control Panel until a push button is pressed, which causes the Operator Control Panel to return to the Home Screen. v Numeric error codes are only used for unrecoverable, fatal errors, otherwise text status messages are displayed. Power-ON Display When the library powers ON or resets, it goes through several internally controlled processes that allow it to get initialized and running. These processes are called Power-On-Self-Test (POST). During the POST the Operator Control Panel displays information that may be meaningless until POST is complete. When the POST is finished, the library displays the Startup screen, then the Home screen. The Startup screen is the first screen that appears after powering ON the library. It contains the following information: v Firmware Rev: the current level of library firmware v Drives: the total number of drives that the library can support v Magazines: the total number of magazines in the library v I/O Station: the current status of the I/O Station While the library is going through its power up cycle you can monitor the state of the library via the OCP; however, you may not be able to make any configuration changes until the unit has completed its initialization routine. Attempts to make changes will be ignored. Startup Firmware Rev: Drive: Magazines: I/O Station: 120R 1 2 empty Idle Random TL4000 a77ug187 Accessor Idle Rand Drive 1 2 Figure 2-1. Power-ON screens Note about the Front Panel LEDs All LEDs are updated during power ON and reset sequences. Upon power ON or software reset, the library illuminates all LEDs as soon as POST allows. When initialization starts, all LEDs are extinguished and the Ready/Activity LED flashes at a rate of approximately one second per cycle. When the mechanical initialization is complete, the Ready/Activity LED will stop flashing and be constantly illuminated. If a library failure occurs, the Ready/Activity LED will turn OFF and the Error LED illuminates. The Operator Control Panel will also display an appropriate error code to help identify the failure. 2-2 Dell PowerVault TL2000 Tape Library and TL4000 Tape Library User's Guide
