1. Rack installation
In this film clip we will demonstrate the installation of an LT260 Base Module with one Expansion Module in a Fujitsu PRIMECENTER M1 rack.
Please note that the rack must be of the deeper 700 millimeter type so that the tape library fits in it.
After having unpacked the Base and Expansion Modules from the transportation packaging, one can see that the Expansion Module is open
both from top and bottom.
The Base Module comes always with a cover plate on the top and in the bottom - these remain intact if no Expansion Module is to be used.
The Expansion Module can be fitted either below or above of the Base Module. The decisive factor is in what height of the rack the Base
Module can be installed; convenient access to the OCP should dictate the installation height of the Base Module and consequently the
Expansion Module resides either above or below thereof.
In this film we will install an Expansion Module below of the Base Module and therefore the first step is to remove the lower cover plate from
the Base Module and place it on the underside of the Expansion Module. This can be easiest done when both modules lie on a table upside
down.
To remove, first push down the locking mechanism and then slide the cover towards the front of the library.
Fitting the cover in its place can be done simply by placing the cover leveled with the front of the library and sliding towards the rear of the
system until the locking mechanism snaps out to lock the cover in its place.
For the installation in a rack it is recommended to use a rack installation lift because even when empty the library weighs over 30 kilograms.
Note, for the next steps it is important that the drives are removed to reduce the weight.
After the rack rails have been installed in the rack according to the instructions given in the User Guide, move the sliding assembly to the front
and extend the middle rails all the way out.
Note; when handling the Base Module in the next steps please note that the bottom of the unit is open and therefore the robotic assembly is
exposed to potential damage.
Raise the Base Module to the appropriate height and move it backwards until the inner rails snap in with the sliding assembly. Now push the
releasing levers on both side of the library and push the library inwards until fully in.
Repeat the same procedure for the Expansion Module; please note that when fitted in the rack the gap between the modules must be less than
4 millimeters.
To ensure trouble free movement of the robot between the Modules they must be properly aligned. For this purpose the alignment mechanism
in the back of the upper Module must be loosened and the alignment pin pushed downwards. It is important that the pin can be lowered down
without any feel of resistance, should this not be the case then move the pin back in its upper position, move slightly one of the Modules until
the pin can be lowered without any friction and consequently tighten the thumbscrew.
With both modules in normal operating position, secure them by tightening the thumbscrews on each side of the Modules.
In our example the Expansion Module was ordered without any Drives and the Base Module was ordered with all six Drives configured.
In the next step the Drives must be fitted, technically there are no restrictions; the bays can be populated in any order.
To complete the installation, enable communication between the Base Module and the Expansion Module by connecting the Extension Cable,
connect the signal cables of the drives and finally the power cables; please use the Installation and Operation Guide as reference.
2. Initial Configuration Wizard
After having powered on the tape library for the first time this screen appears on the Operator Control Panel. It is possible to choose between
three IP address areas that will be consequently used exclusively by the LT260, meaning these addresses must not conflict with addresses of
the customer network.
Before the LT260 can be taken into use further parameters need to be set up.
Please note that for demonstration purposes this video clip has been edited and consequently some of the sequences run faster than in real life.
In reality the initial boot phase to the first login screen takes about two and a half minutes and for the library to be ready for use about six
minutes.

As long as the Ready LED is blinking the library is still busy with the initial start and therefore it is necessary to wait, attempt to login earlier
results in a "Library Busy" message.
After the green Ready LED lights continuously the Attention LED continues to blinking as an indication that the initial settings have not been
set up.
Ex-factory the library does not have an administration password set so the password field can be left empty at login.
Consequently a Wizard is automatically launched to guide through the configuration steps.
A message regarding missing default partition appears and can be at this point in time ignored.
As the first configuration step the Administrator password needs to be set up in the usual way of inputting it twice, it is naturally case sensitive.
In the next step it is possible to give the library a local name and a domain name.
Next configurable parameter is the network settings for the Remote Management Interface; only when these parameters are set appropriately
according to the customer network it is possible to access the LT260 using a remote management client.
Please note that for using the IP version 6 you need to first complete the IP version 4 setup and use the Remote Management Interface to
enable IPv6.
Next items to set up are the time zone, date and time - please bear in mind that the date and time settings are used as a basis for all log
entries during the operation of the system and alone therefore it is very important that these settings are correct.
To complete the Initial Wizard select "Finish" and confirm with OK.
All these settings can be later changed using either the OCP or the RMI - but please note that the administrator password must always be set up
during the initial configuration to enable system login and the network parameters are a prerequisite for being able to use the RMI.
As can be seen from the system details at the top of the screen, the system status is still unconfigured and therefore it is necessary to reboot
the system.
This can be done from the Maintenance menu by choosing System Reboot.
After this the library reboots and after the system test has been successfully completed and the green Ready LED is permanently on the
ETERNUS LT260 can be taken into normal operation.
3. Introduction front
On the front side of the ETERNUS LT260 Base Module there are; access door of the left side magazine, Operator Control Panel, power button,
LEDs, USB port, front window and access door to the right hand side magazine and Mailslots.
The tape library can be switched on by pushing the power button that will consequently lit in green.
The functionalities of the other LEDs are explained in the respective chapter of this Web Based Training.
Powering on the library initiates an inventory of the tape cartridges in the magazines, checking the firmware versions of all modules,
configuring the tape drives and a search of newly added modules.
As the power-on sequence is completed the green Ready LED lights in green thus indicating the library to be fully functional.
The Expansion Module does not have Operator Control Panel; instead the window extends from the top to the bottom of the unit. The cartridge
and drive features are identical with the Base Module.
4. Introduction rear
In the rear side of the Base Module there are always two Power Supplies that provide redundantly power to all the components in the Module.
In the middle there are six bays for the Tape Drives of which a minimum of one is occupied by a Half-Height drive.
In addition to the built-in fans of the Power Supplies each Module has one Chassis Fan.
By removing the Chassis Fan it is possible to access the Drive Power Board bays. The system shown has all six Drive Bays occupied and
consequently both Drive Power Boards must be fitted.
The Control Modules are connected with an Extension Cable.
The Control Module of the Base Module has USB and Ethernet interfaces whereas in the Expansion Module these interfaces are not needed.
The Base Module comes always with two Power Supplies, for the Expansion Module the second Power Supply is a configurable option.
We will have a closer look at all of these modules individually in the respective chapters of this Web Based Training.
5. Introduction to the OCP
Here is the touchscreen of the OCP that provides access to the built-in administration utility of the LT260.
The top of the screen provides some system parameters, from the middle of the screen it is possible to choose the login type from four available
options; User, Administrator, Service and Security.
This is the login screen of the OCP.
First we will log in the library as User, by default none of the accounts have a password set; a password can be though set up using the Security
account.
For User all the other menu options except for Status are not accessible
The OCP returns to a screen saver mode when it has not been used during the defined timeout.
Logging in as an Administrator provides this Home Screen.

Speaker script ETE-LT260-INM-WBT 02/03/2016

Fujitsu Training Academy
Top left is the Home button, right from there the Status Information indicator, in the middle current system status, then system time and date
and at far right the Logout button.
At the top left corner with white background basic system information and below from there two status information fields. Per default the Base
Module information field is larger than that of the Expansion Module; by touching the area below it is possible to enlarge the information field
of the chosen Expansion Module.
The information field shows for each Module the overall status of the Module - green check mark indicating normal operation - the number of
installed drives, the number of used and available cartridge slots and an overview of all drive bays. All drive bays fitted with a Tape Drive also
show the current status of the drive.
Touching a drive bay symbol opens a screen with detailed information of the Tape Drive fitted in it.
A scroll bar appears on the right hand side of the screen when the available information extends beyond the screen size.
To log in with the Service login requires passwords for both Administrator and Service. The Administrator password has been set up during the
initial configuration, for Service there is a default password.
During the rest of this film clip we will do a quick run-through of all the available menu options under menu option Maintenance.
6. Identifying a Failed Component
The upper left corner of the Home Screen provides an overview of the system status, choosing a module provides more detailed status
information that helps to identify what component has failed.
7. Operating the Magazines
Before removing a magazine from the library the respective magazine needs to be first prepared for the removal. Typically you would ask the
local Administrator to operate the tape library to provide access to the magazines should that be needed for the service procedure.
After the magazine or Mailslot has been released for a removal, it can be extended out from its slot, in the case of Mailslot it can be completely
removed from the library.
When re-inserting the Mailslots in the library align first carefully the guides of the magazine with the grooves on the chassis.
Always after a magazine is re-inserted the robotic assembly scans the respective slots to verify and update the inventory.
8. Replacing a Tape Drive
Two things need to be verified before replacing a tape drive; firstly to ensure that there is no tape cartridge in the tape drive to be replaced -
this could well be the case if a backup has been interrupted due to a drive failure.
Secondly, it is always recommended to agree with the local Administrator that no backups are running during a service procedure; although
technically it would be possible to replace a tape drive during a backup in two cases: a) the drive to be replaced is not the only drive in the Tape
Library or b) the drive to be replaced is not the master drive in a multi-drive library.
From the Home Screen you can see the current status of the drives; Empty, Idle and Busy.
If the status is Empty then you can proceed, if the status is Idle then you need to first move the tape cartridge out of the drive.
Again, typically you would ask the local Administrator to do that but for demonstration purposes we will show the procedure here.
From Home Screen choose Operations, next choose Move Media and then select the drive in question as the source and for example a Mailslot
as a destination.
If the drive status is Busy - meaning that the drive is currently used either by the backup software or by internal tests - then please ask the local
Administrator for advice on how to proceed.
After the prerequisites for a drive replacement have been fulfilled then the last action before physically removing the drive is to power off the
drive.
For this purpose it is necessary to log in as user Service, enter the Configuration menu, choose option Drives and select the drive to be powered
off. By deselecting the Power On check box and pressing Submit the Drive will be powered off.
Now the signal cables can be disconnected, the thumbscrews loosened and consequently the drive can be removed by pulling it out of the bay.
Installing a replacement drive can be done by inserting it in the bay and carefully pushing it in its place and lastly fastening it in its place with
the thumbscrews.
Next re-connect the signal cables.
After the power has been re-established the drive will be automatically initialized and is ready to use after it appears in the Home Screen of the
OCP.
9. Adding a Tape Drive
Before adding a Tape Drive one needs to first ensure that the necessary power supply for the drive is available. In a compartment behind the
Chassis Fan there are two slots for two Power Boards. The rightmost slot is always occupied by a Power Board that supplies power to the Chassis
Fan and three Tape Drives that can reside in any drive bay within the Module.
If the Tape Drive to be added is the fourth drive then it is necessary to have a second Power Board fitted. Second Power Board can supply current
for additional three drives.

Speaker script ETE-LT260-INM-WBT 02/03/2016

Fujitsu Training Academy
When adding a drive it is technically irrelevant to which bay it is fitted; even if partitioning was used albeit in a partitioned configuration it
makes sense to arrange the Tape Drives and respective tape cartridges in physically close entities.
Remove the cover plate of the chosen bay.
By holding the drive aligned with the bay carefully slide it all the way in and fasten in its place using the thumbscrews.
If the added drive has a SAS interface then it is enough to connect the respective SAS cable, if the drive is of Fibre Channel type then in addition
to connecting the Fibre Channel cable it is necessary to set the Fibre Channel port parameters as described in the Installation and Operation
Guide.
In both cases the drive will be automatically powered on after which it will be ready to use and the respective symbol appears in the Home
Screen. Please be aware that the new LTO-6 [l-t-o-6] IBM drives look slightly different than its predecessors from HP.
10. Replacing Power Supply
Defective Power Supply can be identified by its LEDs; either the midmost amber LED is lit or all three LEDs are unlit.
After having unplugged the power cable the thumbscrews of the Power Supply can be loosened and consequently the unit can be removed
from the chassis.
Installing a replacement Power Supply is very straightforward; align the Power Supply with its bay and carefully move inwards until it sits firmly
in its place. As with all the modules, use the blue thumbscrews to fasten in its place.
After having reconnected the power cable and the short initialization phase the Power Supply is ready to use. In normal operation the white
and green LEDs are lit and the amber LED is unlit.
11. Replacing Controller Board
Although the configuration of the library is stored also in the chassis and is restored to the Controller Board after a replacement, it is always
recommended to save the configuration of the library to a file before replacing the Controller Board - naturally providing the nature of the
failure allows this.
Controller Board replacement is obviously an offline service procedure.
Always before carrying this service task consult the local Administrator to ensure that no backups are currently running and that none are
planned for the offline service time.
The procedure is started with a soft shutdown of the library by pushing and holding the power button for 5 seconds, after which a pop-up
window appears with a question to which position the Robotic Assembly should be moved; select Park Position.
Should the library not react to applying the power button then it is necessary to push and hold the power button for 10 seconds.
By looking inside the Base Module window, next verify that the robotic assembly is in its parked position behind the OCP.
Following steps are carried out in the back side of the library. First remove both power cables and then detach all cables - and potentially a USB
device - from the Controller Board. Ethernet and USB interfaces are available only on the Base Module.
Before proceeding with the next step please make sure that you are following the appropriate ESD precautions.
Loosen the thumbscrews and use them to pull the Controller Board out of its slot.
When inserting the replacement Controller Board first align it with the slot rails and then push carefully fully in its slot. After having fastened
the Board in its place with the thumbscrews you can re-connect first all signal cables, re-insert the USB device - if any - and as last reconnect
the power cables.
After powering on the LT260 it is necessary to verify that the library has re-established normal operational status.
If the Controller Board of the Base Module was replaced then it is necessary to verify that the firmware version of the Controller Board is
up-to-date.
The firmware of the Controller Board in the Expansion Module is always automatically updated after a replacement.
12. Replacing Chassis Fan
Replacement of the chassis fan is a very straight forward operation as the fan assembly contains no active components. Open the thumbscrews,
remove the defective fan, replace with a new one and finish off by tightening the thumbscrews of the new fan.
13. Replacing a Drive Power Board
As it is necessary to power off the system for this procedure, before proceeding first verify with the local Administrator that no backups are
running or planned for the time of the maintenance procedure.
If not already done, first have a look at the system log to get a confirmation regarding the defective component.
Similarly as with the replacement of the Controller Board, first power off the LT260 and verify that the robotic assembly is in parked position.
After having disconnected the power cables, remove the chassis fan to have access to the Power Board compartment.
IMPORTANT: As the Drive Power Board is a non-protected bare printed circuit board with exposed electrical components, it is extremely
important to follow appropriate ESD precautions when handling the board.
Remove the defective Board from the chassis.
Align the replacement board with the alignment rails and slide the board into the compartment until seated firmly. Push the latch up until it
snaps into place.

Speaker script ETE-LT260-INM-WBT 02/03/2016

Push the Chassis Fan in its place and tighten using the thumbscrews.
After reconnecting the power cables switch on the LT260, ensure that the library accomplishes the initialization phase and reaches normal
operating status.
As a reminder, like always after a maintenance procedure, firstly verify that the fault status of the replaced component - and the related
components, like the Drives in the case of defective Drive Power Board - has been mended. Secondly, delete the related fault event or events
from the Event Log.
14. Removing and replacing Robotic Assembly
Because the following procedure requires the Base Module and Expansion Module to be detached from each other, it is very important that the
robotic assembly is in its parking position behind the OCP.
As a preparation for removing the Robotic Assembly all cables from both the Base Assembly and Expansion Module have been removed and
the two Modules are detached from each other by having moved the alignment pin in the upper position.
Always before extending a unit from a rack make sure the necessary measures are taken to prevent the rack from tilting.
Extend the Base Module fully from the rack so that you have access to the top cover.
Then remove the top cover by pressing down the locking catch and at the same time moving the cover towards the front of the library.
Slide the cartridge carrier toward the center of the robotic assembly to access the robotic locking lever.
Move the blue locking lever first to left, then towards the front of the library and then to the right.
Now pull up very slowly - not more than about one centimeter per second - the robotic assembly upwards.
Very carefully lift the assembly out of its moving mechanism not to damage the spooling cable attached to it.
Place the mechanism on top of the Base Module while observing the spooling cable not being damaged.
Detach the cable from the assembly using a small flat head screwdriver.
Before installing the Robotic Assembly ensure that the blue locking pin is in unlocked position.
As the first step reconnect the spooling cable and then use any of the four gears at the corners of the robotic assembly to align the pins
horizontally.
Place the Robotic Assembly at the top of the moving mechanism and let the assembly sink downwards - it does not sink by itself then you may
have to push it slightly to make it move downwards. Let the Robotic Assembly fall until it resides approximately in the parking position behind
the OCP.
Now turn the blue locking lever to locked position.
Now you can replace the top cover, push both Modules back in the rack and align them accordingly, connect all cables and switch the library
power on.
Make sure the LT260 establishes normal operating mode.
15. Replacement of the Spooling Cable
Before being able to replace the Spooling Cable the Robotic Assembly needs to be removed, please refer to the respective video clip.
In order to have access to the Spooling Cable the left side Magazine needs to be pulled out. As the library is at the moment switched off it is
naturally not possible to release the Magazine using the respective menu option, instead a mechanical release lever needs to be applied.
This can be found about in the middle of the magazine, between the door and the magazine.
Push the lever and simultaneously extend the magazine out from the library chassis.
To remove the Spooling Magazine it is necessary to release its locking lever while lifting it upwards.
Replacement is very simple by sliding the cable assembly to its place until the locking lever snaps on.
Rest of the procedure is the same as when replacing the Robotic Assembly; please refer to the respective video clip.
16. Replacement of the OCP
For replacing the OCP the library must naturally be switched off.
After opening the magazine access doors, use a small screwdriver or similar and place it in the hole on the top side of the OCP. Push gently to
loosen the release catch and pull the corner of the OCP slightly outwards. Repeat with the other corner of the OCP.
While carefully tilting and lifting the OCP, pull it outwards to have access to the connection cable and release it from its connector.
When installing the OCP, connect first the cable and before pushing the OCP in its place make sure the cable is correctly routed in the channel
behind the clear plastic window.
Replacement of the front panel of the Expansion Module follows the same procedure, but naturally without the OCP cable.
Switch on the library, before the normal initialization phase starts it is necessary to calibrate the touchscreen, for that follow the instructions on
the screen.
Consequently, make sure the LT260 establishes normal operating mode.
