Users Guide
4. If the power supply seems to be delivering power to the library; but air does not flow from the power-
supply cooling fan grill on the rear of the library, replace the library.
Isolating drive problems
1. Ensure that the drive rmware is at the latest level (visit http://www.dell.com/support).
2. Cycle library power.
3. If the drive is experiencing permanent or temporary errors or if the Clean LED is lit on the front panel of
the library, clean the drive.
4. Run Library Verify.
a. If the test fails, replace the library.
5. With the host interface test tool, ITDT, run the Scan functions to verify that the host application
interface can detect the drive and the library. To further test the interface communication path, run the
Test Device function, if available, after the drive is selected. This function writes and reads data across
the interface, also sending a command to the drive to run the internal performance read/write test.
6. If the host tool, ITDT, cannot detect the drive or library, look for problems with the host interface
cabling, the HBA, the device driver, or the backup application software.
Isolating Web User Interface problems
1. Verify that you entered the account name and password correctly. The account name and password
are case-sensitive.
2. Verify that other library users are not entering commands from the Web User Interface or Operator
Panel at the same time you are issuing commands.
3. Ensure that library rmware is at the latest level (visit http://www.dell.com/support
).
4. Ensure that the Ethernet cable is securely plugged in the rear of the library at the Ethernet port.
5. Ensure that the library has a valid Serial Number.
6. Ensure that the correct IP, netmask, and gateway addresses are keyed into the network parameters.
7. Ensure that the correct IP address is being used on the web browser.
8. If the Ethernet connection is a direct connection between the PC and the library, a special
"crossover" Ethernet cable is required.
Note: On newer PCs, either straight through or crossover Ethernet cables might be used since the
crossover requirement is provided internally.
9. Check the Ethernet cable carefully (or try another cable) and, if the cable is connected to a network
hub or switch, try a different port.
10. If the Web User Interface is still malfunctioning, refer to “Contacting Dell technical support” on page
111.
Isolating host attachment interface problems
After successfully exercising “Isolating drive problems” on page 107, and more specically “Running
library verify diagnostic procedures” on page 62 from the Operator Panel (Service > Library Verify), the
following procedures are suggested to help isolate the failure to properly establish connectivity to the
Host Bus adapter (HBA).
1. Use the ITDT-DCR utility to evaluate connectivity from the HBA through the cabling to the drive. ITDT-
DCR does not require separate device drivers, thus the Operating System can scan, and nd all the LTO
devices that are attached.
