Problem
Power
Autoloader will not turn on
Power-on test failed. An error message on
the front panel is displayed.
The autoloader power failed while a tape
was in the drive and did not return to the
ready state after the power came on.
Tape Movement
An error message is displayed after
inserting the magazine or loading tapes.
Tape stuck in drive.
Tape stuck in transport.
Tape stuck in back storage slot.
Transport will not load or unload a tape.
Media
Tapes or cleaning cartridge incompatible
with drive.
Connections
Host does not detect the autoloader.
Backup software application on the host
does not detect the autoloader.
Changed drive SCSI ID, but the new ID is
not recognized by the host computer.
Host responds slowly or stops responding
after connecting to the autoloader.
Network Monitoring and Operations
The remote management card interface is
slow in updating the Web pages or does
not display clearing.
Recovery actions
Check the power cord connection. Make sure the power (standby)
switch is on. Make sure there is power to the outlet. Try another
working outlet. Replace the power cord. Check that the LEDs on the
back of the autoloader are on and the fans are turning to ensure the
autoloader is receiving power.
Verify that all tapes are fully inserted in the magazine and that athe
magazine is fully installed inside the autoloader. Check that the internal
packaging has been removed. Make sure the door is closed. If the
power-on test fails again, look at the error code and refer to
"Understanding error states" on page 31 for more information.
Check that the LEDs on the back of the autoloader are on and the fans
are turning. Turn the autoloader off and then on.
Verify that the tapes are inserted correctly in the magazine. (See
"Accessing tapes in the autoloader" on page 15.)
Turn the unit off and then on and retry unloading the tape from the
autoloader front panel. Ensure the backup host software is not reserving
the slot. The backup software needs to cancel the reservation.
Run the Recalibrate Loader test. Open the door. Remove the magazine
and then gently ease the tape out of the transport. Do not grasp the
back of the transport assembly. Call your service representative.
Using the front panel display, open the door. Pull the door down, and
remove the magazine. Push the tape into the back slot until it clicks into
the slot. Push the tape in again until it clicks and releases.
Run the Recalibrate Loader test. Ensure you are using the correct tape
type and magazine for your autoloader drive configurations.
Ensure you are using media and a cleaning cartridge that is compatible
with the drive.
Check that the autoloader is terminated and properly cabled. Ensure the
terminator and host bus adapter card are compatible with the
autoloader and SCSI bus type (HVDS or LVDS). Check that the
autoloader is recognized by the operating system. Check that the SCSI
host bus adapter card and backup software are compatible with the
autoloader.
If the backup software detects the drive, but not the autoloader, check
that the Autoloader Module or Changer Option is included with the
backup software. Most software packages require an addtiional module
to communicate with the autoloader robotics. If the backup software
detects the autoloader and not the drive check that you have installed
the correct backup software driver and that there are no conflicting
drivers installed.
Check that all SCSI devices on the same bus have different ID numbers.
Restart the host. If the drive remains at SCSI ID 5, regardless of how it
is set, then the drive is not communicating with the autoloader. Call
your service representative.
Check the SCSI IDs of all devices on the host to ensure there are no
conflicts. Check that the backup software does not require SCSI IDs to
be in a certain order.

display resolution is set to 800 x 600 and the color palette is set to 65535
colors or higher. To speed up the display of pages, be sure to bypass
