The Sony AIT-4 drives double the Spectra 2K library’s capacity and transfer rate. Review
this document for information about AIT-4 and about upgrading your library to take
advantage of AIT-4 drive technology.

Preparation
1. Identify the drive or drives to be upgraded in your Spectra library.
2. Make sure you have an AIT-4 drive for every drive you are replacing, and a
library firmware upgrade tape.
3. If you are going to return the drives to Spectra Logic (for example, for trade-ins
or in conjunction with a prepurchase), reserve the drive packaging for later use.
4. Download the AIT-4 driver from the Sony Web site, then install it on the library’s
host system.
5. Make sure all backup procedures are halted, and that you set aside enough time
to complete the upgrade. Allow 15 minutes to upgrade firmware, and another
15 minutes per drive to replace the old drive with the new.
Updating Firmware
To upgrade your Spectra 2K library, have on hand:
• A Spectra Logic firmware code tape
• A small flat head screwdriver

Loading the Firmware Code Tape
To load the firmware tape:
1. Drives are located at the bottom of the library. Move the picker away from its
lowest position, so that you can access the drives:
•Open and close the library door, which forces the picker to move.
•When the picker is positioned in the middle or the top of the library,
open the door again.
2. Carefully insert the tape into the drive with the write-protect tab facing out and
the window facing up. If you have a two-drive library, make sure you load the
tape into Drive 1—the drive closest to the data cartridge magazine.
Preparing the Library
1. Power off the library.
2. Disconnect the SCSI cable from the back of the library.
3. Move the library to a position that provides easy access to the front and rear of
the library.
4. Locate the configuration switches on the rear of the library, and write down the
settings of the library configuration switch and the SCSI ID switch.
5. Use a small screwdriver to turn the library configuration switch to 4 and the
library SCSI ID switch to 7.
Loading the New Firmware
1. With the library door open and the picker away from its lowest position, power
on the library. The library begins the firmware update process, during which time
the picker parks at the bottom of the library, and its LED turns amber for the
duration of the firmware upgrade. This process typically requires less than five
minutes.
2. When the drive ejects the tape, the upgrade is complete; remove the tape from
the drive.
If the tape doesn’t automatically eject from the drive: make sure the
picker is parked at the bottom of the library, then press Eject on the front
of the drive.

Resetting Original Values
1. Turn off the power to the library.
2. Use a small screwdriver to return the configuration switch to the default
position of 0 and the library SCSI ID to its original setting.
3. Reconnect the SCSI cable to the back of the library.
Installing the AIT-4 Drive
Removing the Back Panel and Fan
1. To remove the rear access panel, remove the two lowest screws on the back of
the library with the Phillips screwdriver (Figure 1), then lift the bottom panel and
work it down, so that the tongues at the top of the panel can clear their slots
(Figure 2), using caution as the edges may be sharp.
Figure 1 Remove the rear access panel screws
(Fibre Channel library shown).
Figure 2 Remove the rear access panel.

2. Unplug the fan and serial port cables inside the Spectra 2K. Set the panel aside
(Figure 3).
Removing the Drive
1. Unplug the SCSI ID cable and the power supply cable from the library and drive
(Figure 4).
2. Unplug the SCSI ribbon from the drive (Figure 4), pulling the ribbon straight
back from the connector without pulling other wires.
Figure 3 Unplug the fan and serial port cables (Fibre Channel library shown).

3. Loosen the wing-nut screw on either side of the drive (Figure 5), then holding
the drive edges, slide the drive out of the library (Figure 6).
Installing the Drive
1. Remove the drive from its packaging.
2. Attach the power cable to the new drive, and make sure both the power cable
and SCSI ID cable are securely attached to the drive (Figure 7).
Figure 5 Loosen the wing-nut screws. Figure 6 Slide the drive out of the library.

3. Slide the drive into the drive slot. Drive 1 fits above the drive rails, Drive 2 fits
below them. Use the top slot if you are installing only one drive. Keep the
power cable to the right as you insert the drive into the library (Figure 8).
4. Tighten the wing-nut screws on the drive you just installed (Figure 9), then
connect the power cable to the library socket (Figure 10).
Figure 8 Always place the first drive in the top slot; the second
drive goes in the bottom slot.
Figure 9 Turn the screws clockwise to tighten. Figure 10 Connect the power cable to the library socket.

5. Connect the power cable to the drive. If you are attaching a second drive, make
sure that you correctly connect the power cable for each drive (Figure 11).
6. Attach the SCSI ribbon cable to each drive. Attach the last plug on the SCSI
ribbon cable to the bottom drive. If you are attaching only one drive, leave the
last connector on the SCSI ribbon cable unattached (Figure 12).
7. Attach the SCSI ID cable to the library. Plug the Drive 1 (top drive) SCSI ID into
the left connector. Plug the SCSI ID for Drive 2 (bottom drive) into the
connector on the right (Figure 13).
8. Confirm that the wiring is correct and secure.
9. If you have a second drive, repeat this procedure.

Attaching the Rear Panel
1. Attach the fan and serial port cables (Figure 14).
2. Attach the rear access panel with the two Phillips screws.
Setting the SCSI IDs
After you have installed the new drive, verify the settings of the SCSI ID switches,
located just above the drive access area. A SCSI Spectra 2K library may require up to
three SCSI ID’s depending on the number of drives installed. Verify that each of the SCSI
ID’s are set correctly; the library and each drive must have its own number. A Fibre
Channel Spectra 2K has only Library and Config switches on the rear panel. For Fibre
Channel, make sure the Library switch is set to “2”.

Completing the Drive Upgrade Process
1. Check your operating system manual, and follow instructions as necessary (for
example, reconfigure the kernel) to make sure the operating system recognizes
the new drive files.
2. Test your drives. For example, back up a set of data that includes one
executable program; restore the data to a temporary directory; then read the
restored data and run a restored program. Refer to your backup software
documentation for a more specific procedure. After you have performed a drive
test successfully, continue.
3. Restart backup processes
Returning Old Drives
To return old drives to Spectra Logic (for example, if you are trading in the drives, or if
you pre-purchased the new drives), use the AIT-4 drive packaging and return the drives
to Spectra Logic (North America) or contact Support for assistance in determining how
to return the drives.
