page 5-60 for the web or “Service: Run Tests” on page 5-31 for the OCP If theproblem is persistent, contact Dell technical support.7. If the library is taking an extended amount of time in recovery to completeinitialization, perform an inventory, or executing a cartridge movement withinthe library, and, after finding the magazine cell fiducials to be present with novisible damage and correctly installed, suspect the sensor/emitter on theaccessor mechanism to be inoperable. Execute a Library System Test. See“Service Library: Perform Diagnostics” on page 5-60 for the web or “Service:Run Tests” on page 5-31 for the OCP If the problem is persistent, contact Delltechnical support.Isolating Web User Interface ProblemsIf the Web User Interface is not functioning at all or if it is intermittentlyfunctioning, review the following steps to ensure that it is properly configured, or,to help determine which CRU or part needs to be replaced. The complete WebUser Interface electronics reside on the library controller card CRU.1. Ensure that the ethernet cable is securely plugged in the rear of the library atthe ethernet port. See 7 on the “Rear Panel” on page 1-3.2. Ensure that the correct IP, Netmask, and Gateway addresses are keyed into thenetwork parameters. From the Operator Control Panel, navigate to Configure →Network.3. Ensure that the correct IP address is being used on the web browser. If you geta security certificate alert when logging in to the Web User Interface, you caninstall the certificate or allow an exception (depending on the internet browseryou are using). Even though with some browsers you will still receive asecurity certificate warning/error each time you log in to the Web UserInterface, your transmission is secure. SSL is enabled when the URL to yourlibrary begins with https:// and some browsers will show a lock.4. If the ethernet connection is a direct connection between the PC and the library,a special "crossover" ethernet cable needs to be used.Note: On newer PCs, either straight through or crossover ethernet cables maybe used since the crossover requirement is provided internally.5. Check the ethernet cable carefully (or try another cable) and, if the cable isconnected to a network hub or switch, try a different port.6. If the Web User Interface is still malfunctioning, replace the Library ControllerCard CRU (refer to “Replacing a Library Controller Card” on page 10-11).Isolating Accessor Scanner ProblemsIf the server has reported inventory problems relating to inability to read bar codelabels, or, if some or all of the cartridge labels are not being displayed on the WebUser Interface, use the following procedure to determine if the scanner (libraryenclosure CRU) needs to be replaced.1. Ensure that a supported bar code label (or labels) are being used.2. With library power OFF, reseat the library controller card CRU (refer to“Replacing a Library Controller Card” on page 10-11), and then switch librarypower ON.3. Perform a re-inventory via the Operator Control Panel (Control →Re-Inventory) and view the inventory via the Web User Interface (MonitorLibrary → Inventory) to determine if the labels are now being read.Chapter 7.
