About Preventative Maintenance
Purpose
The preventative maintenance procedure is intended to provide the best possible
operating results from the Spectra 10K library.
Time Involved
This procedure takes approximately two hours.
Tools Needed
◗A credit card or thin piece of plastic
◗A #1 Phillips screwdriver with a long handle (8-inch minimum)
◗A large flat head screwdriver
◗A can of compressed air
◗A vacuum cleaner with static-free attachment (hard plastic nozzle)
◗A new Spectra 10K library air filter
◗A Sony cleaning tape
◗Four bar-coded scratch tapes

Preparing the Library
1. Use your backup software to remove all tapes from the library, noting which tapes
were in which slots.
2. Shut off all power to the library.
3. Shut down the host system and switch off the power.
4. Remove the library’s AC power cord from the AC power outlet.
5. Carefully remove SCSI cable connections from the back of the library.
6. Move the library to a clean work space with plenty of room, so that you have access
to all sides of the library.

Changing the Air Filter
1. The front panel of the library has a grill on the left, and on the left end of the grill
is a groove. Use a credit card or other piece of plastic to open the grill.
2. Swing open the grill.
3. Remove the air filter.
4. Inspect the grill; if the grill is dirty, clean it.
5. Install the new air filter.
6. Close the grill and snap it shut.
Note: Filters should be checked on a monthly basis or after the library has
been moved. On average, the library filter needs changing once
every three months. If the environment is particularly dirty, the
filter needs to be replaced more frequently.

Cleaning the Door Sensor
1. Notice the four small holes in the top of the door for LED sensors: two holes toward
the back of the door and two holes near the front of the door. If these holes are
clogged with dust or other debris, the door sensors will fail to operate.
2. Use the can of compressed air to blow out the four holes and dislodge any debris.
Use a plastic attachment to direct air into the holes.
Note: The door sensor should be cleaned once every three months, at a
minimum.

Internal Maintenance and Cleaning
1. Use a large flat head screwdriver to remove the thumbscrews on the back of the
library.
Caution: The library contains static sensitive devices. Please use a static
dissipative wrist strap or other ESD equipment and tools for this
process.
2. Remove the cover by:
a. Sliding the cover backwards, then
b. Lifting up the cover.
3. Use a #1 Phillips screwdriver to loosen the two captive screws holding each drive in
place.

5. Use a #1 Phillips screwdriver with a long shaft to loosen the eight captive screws
holding the carousel to the library chassis.
Caution: Captive screws cannot be completely removed. Loosen the screws
sufficiently to disengage them from the chassis.
6. Rotate the robotic arm so that the gripper jaws point to the rear of the library, as
shown below; the carousel does not come out unless the gripper jaws face the rear
of the library.

Caution: Do not force the carousel out of the library. The base of the
robotic arm is not a circle, and the carousel does not lift straight
up and out. The carousel comes out easily if done correctly, as
outlined in Step 7, below.
7. Remove the carousel.
a. Lift the carousel up and off the guide pins, about 1/2 inch.
b. Lift the front of the carousel so that it is even with, or a little higher than, the
base of the robotic arm.
c. Move the carousel toward the rear of the library so that the front of the
carousel touches the robotic arm base.
d. Lift the rear of the carousel above the robotic arm base. The carousel should
now be clear of the robotic arm base.
e. Carefully lift the carousel up and out of the library.
8. Use a static-free vacuum cleaner to remove any debris from the bottom of the library.
9. Clean the tape guides in the carousel.
10. After vacuuming, use a can of compressed air to clean the boards, power supply,
components, and any section where a static-free vacuum might not be able to reach.
Caution: Blow dust and debris away from the tape drives.

11

11. Before re-installing the carousel, make sure that the SCSI ribbon cable is not pinched
or twisted, and that it stays out of the way of the carousel.
12. Re-install the carousel, making sure that all drives and cables are out of the way.
Caution: Make sure that the door cable is not pinched between the carousel
and the base plate or UCM board (see the pictures below).
13. Slide the drives back to their original positions next to the carousel and tighten all
of the captive screws.
Note: Remember that there are eight thumbscrews for the carousel and
two screws each for the drives. If necessary, reference the diagram
on page 9.
14. Proceed to Checking the Cables on page 12.
Door cable pinched by carousel. Door cable free to move.

Checking the Cables
1. Check the SCSI cables on the UCM board and verify that they have not come loose
during the cleaning.
2. Make sure that boards are firmly seated on the base plate.
3. Check all cable connections (including the drive cables) and make sure that all cables
are securely attached to boards.
4. On differential units, check the SCSI cables on the SDC board. Make sure that the
board is fully seated.
5. Replace the library cover and secure the cover with the three thumbscrews on the
rear of the library.

Cleaning the Drives
Note: Although Sony AIT drives come with a built-in cleaning function,
Spectra Logic recommends cleaning the drives every 100 hours of
use. If this cleaning frequency does not address intermittent read
and/or write errors, reduce the time between cleaning by half.
Continue adjusting the cleaning frequency until you reach optimal
operation. Allow the environment to determine how often you
clean the drives; each environment is unique.
This procedure must be performed with the library powered on in stand alone mode
(no host system connected to the library).
1. Attach SCSI terminators to the back of the library.
2. Reconnect AC power to the library.
3. Turn on power to the library.
4. Wait for the library to come to a Unit Ready state before proceeding.
Drive Cleaning Procedure
1. From the main menu library, select the drive you want to clean.

14
Spectra 10K Library Preventative Maintenance Guide
2. On the Drive Info screen, select Clean Drive.
3. This brings up a window with the message Put cleaning tape in door. Insert the Sony
AIT cleaning cartridge into the cartridge door and select OK.
The robot takes the cleaning cartridge from the door and inserts it into the drive.
When the drive has finished the clean cycle, the cleaning tape is moved back to the
door for removal.
4. Repeat the above procedure for each installed drive.
5. Select Main to return to the Main Menu.

Final Testing
This procedure must be performed with the library powered on in stand alone mode
(no host system connected to the library).
1. Attach SCSI cable connections to the back of the library.
2. Reconnect AC power to the library.
3. Turn on power to the library.
4. Wait for the library to come to a Unit Ready state.
Read/Write Confidence Test
Use a scratch tape for the following test. Make sure that all drives are empty and that at
least one slot in the carousel is empty.
1. From the main screen, select Menu.
2. Select Diagnostics.

17
Spectra 10K Library Preventative Maintenance Guide
6. Wait for the tape to move back to the door after the test is complete.
7. Record the values for all rows and columns in the display.
8. The values returned are tape-type dependent and should appear as follows:
◗For AIT-1, the values should be less than 02.00 percent.
◗For AIT-2 and AIT-3, the values should be less than 04.00 percent.
Note: If the results on any drive are higher than the percentage listed
above for your tape type, contact Spectra Logic Technical Support
at [phone] or at [phone], or send an e-mail to
[e-mail].
