CAUTION Make sure that all peripheral devices connected to the host computer have been
properly shut down. If the host computer is connected to a network, check with the system administrator before switching off power.
Removing the Customer Access Panel
1. Switch off power to the host computer before you connect the jukebox
NOTE The jukebox ships from the factory with two screws securing the bottom of the
customer access panel to the side of the jukebox. These screws are removed during the process of unpacking and removing the jukebox from the shipping pallet.

Jukebox
These screws may not have been replaced.
It is a good idea to use the screws to secure the access panel to the jukebox since they must be in place if the jukebox is ever reshipped.
If you have to replace these screws, they are 6/32 x .437.
2. Remove the customer access panel by pulling on the bottom of the panel and then lifting it off (see Figure 1-1). (If screws are installed, use a flatblade screwdriver or T-15 Torx driver.)

Setting Up the Jukebox
Connecting a 4- or 6-Drive Jukebox
Refer to the following diagram in the next steps.
3. Select single-ended (“A”) or differential (“B”) interface using the SCSI interface selection switch (see the arrow on the diagram ).
The diagram shows connecting a cable to the differential (“B”) interface.
4. Connect a cable between your host computer and either port of the jukebox SCSI connectors of your selected interface type (the example diagram shows using the “B2” port on the differential interface).
Route the cable through the slot at the bottom of the right side (“C”).
5. Plug a SCSI terminator into the unused SCSI port of interface type you chose (the example diagram shows the terminator at “B1” because “B2” was used for the cable ).
If you are using the differential interface, use a 68-pin high-density terminator. If you are using the single-ended interface, use a 50-pin high-density active terminator.
Figure 1-2 Connecting a 4- or 6-Drive Jukebox
6. Plug a SCSI terminator into one of the SCSI ports on the unused interface. Only one terminator is necessary on an unused interface.
The example diagram shows the terminator on the single-ended interface connector A2 but the terminator could have been placed on A1”.
Use an active terminator if you are terminating a single-ended interface.
1-10 Chapter 1
Page 23
Setting Up the Jukebox
Connecting a 4- or 6-Drive Jukebox
If you are terminating a differential interface, use a 68-pin high-density terminator. If you are terminating a single-ended interface, use a 50-pin high-density active terminator.

CAUTION Make sure that all peripheral devices connected to the host computer have been
properly shut down. If the host computer is connected to a network, check with the system administrator before switching off power.
Removing the Customer Access Panel
1. Switch off power to the host computer before you connect the jukebox.
NOTE The jukebox ships from the factory with two screws securing the bottom of the
customer access panel to the side of the jukebox. These screws are removed during the process of unpacking and removing the jukebox from the shipping pallet.
These screws may not have been replaced.
It is a good idea to use the screws to secure the access panel to the jukebox since they must be in place if the jukebox is ever reshipped.
If you have to replace these screws, they are 6/32 x .437.
Refer to the following diagram in the next steps.
2. Select single-ended (“A”) or differential (“B”) interface using the SCSI interface selection switch (see the arrow on the diagram ).
The diagram shows connecting a cable to the differential (“B”) interface.
3. Connect cables between the two host adapters on your host computer and two SCSI interfaces on the interface module.
You can connect the two cables to two interfaces of the same type of different types (single-ended or differential). If you use two different types of interface, check that your jukebox application software supports this.
The diagram shows cable connections to the differential SCSI interface on both interface cards at “B2.” One cable is connected to Bus 1 and the other cable is connected to Bus 2.
Route the cables through the slot at the bottom of the right side (C).

5.
Terminate the daisy-chained bus by plugging a terminator into the unused port of the second interface (the diagram show the terminator in port B1). In this example you would use a 68-pin differential terminator in “B1.”
A differential interface port uses a 68-pin high-density terminator. A single-ended interface port uses a 50-pin high-density terminator.
The same cabling can be done using the single-ended ports.
CAUTION Do not daisy-chain between single-ended and differential interfaces.
6.
Plug a SCSI terminator into one of SCSI ports on each unused interface (the example diagram shows the terminators on the single-ended port at A2 for both interfaces). The terminators can be placed on either port of the unused interface.

Connecting the Jukebox With Other SCSI Peripherals
Connecting the Jukebox With Other SCSI Peripherals
NOTE Operating this jukebox with other peripherals on the same bus is supported, but not
recommended.
In most circumstances, the recommended configuration for this jukebox is as the only device on a SCSI bus. However, your use of the jukebox may be such that other devices could be connected to the bus without a loss of performance.
It is possible to connect this jukebox on a bus with additional peripherals in many different ways (depending on your model):
a 4- or 6-drive jukebox using basic SCSI addressing or Logical Unit Numbering (LUN) addressing
a 10-drive jukebox with one host adapter and with LUN addressing, daisy-chaining Bus 1 and Bus 2 together or a 10-drive jukebox using two host adapters, LUN addressing, and using both BUS 1 and Bus 2 interfaces
a 10-drive jukebox with two host adapters and using LUN addressing
There are many issues that must be considered when connecting other devices on a bus with this jukebox, including the following:
how the jukebox is used; archiving, backup, near-line storage. What performance must be maintained
how the additional peripheral will be used. How much demand will it place on the bus
whether you will be mixing wide and narrow devices on the bus.
whether you are using both internal and external segments on your SCSI host
adapter
whether your bus is single-ended or differential
NOTE Appendix B provides a brief overview of SCSI and the issues you must consider
when placing other peripherals on the same bus with this jukebox.

Setting Up the Jukebox
Configuring Write Verify
Configuring Write Verify
The write verify configuration ensures that data is written reliably to an optical disk. The jukebox ships with write verify enabled. Many software applications also default to this method of writing.
Writing data on a magneto-optical disk requires two passes. The first pass erases the data in the sector to which data will be written. The second pass writes new data to that sector.
When write verify is configured to ON, an additional pass is made over the sector. This third pass verifies that all data is written correctly to the sector. To add to the reliability of your data, Hewlett-Packard recommends that you maintain the default ON setting for write verify. Note that when write verify is ON, write operations take more time.
If you choose to change the write verify configuration to OFF, refer to “Configuring Operating Configurations” in Chapter 3.

The optical disks that you use with your jukebox are an integral part of the storage process. This chapter provides information on the following topics:
choosing an optical disk type
labeling optical disks
write-protecting optical disks
caring for optical disks
IMPORTANT Hewlett-Packard conducts extensive product quality testing to ensure it’s
magneto-optical media is unsurpassed in quality -- far exceeding ISO, ANSI, and IEC industry standards requirements. In addition, HP conducts exhaustive media compatibility and interchange testing to ensure maximum interaction reliability between HP jukebox drives and HP media. Using HP optical media with HP jukeboxes is the best way to ensure your datas integrity and accessibility.
Thats why HP recommends using HP-brand optical media with its jukeboxes.

Using Optical Disks
Choosing an Optical Disk Type
Choosing an Optical Disk Type
Two disk types are available for use in the jukebox: rewritable disks and write-once disks.
To choose which type of disks to use, consider these points:
Rewritable optical disks--data can be repeatedly written and erased.
Write-Once optical disks--data can be written only once, and the data cannot be
altered or erased. If you have a need for data security and audit trails, write-once disks may be a good disk choice.
Rewritable and write-once disks come in sector sizes from 4,096 bytes/sector down to 512 bytes/sector (see Table A-1 in Appendix A). The sector size you choose depends upon what type of operating system you have in your host computer and which software package you use to manage files stored on the jukebox.
Optical Disks
Using
NOTE Do not use write-once disks in a computer system that does not support write-once
disks. Check that your jukebox application software supports write-once disks.

Using Optical Disks
Labeling an Optical Disk Cartridge
Labeling an Optical Disk Cartridge
Make it a practice to label your optical disk cartridges. You are provided adhesive labels with each disk for this purpose. Here are some suggestions for labeling:
NOTE Your jukebox application software may label your optical disk slot locations
differently. Use your application to check disk locations prior to labeling the disks.
storage slot location (1, 2, 3, ... )
date of format or initialization
disk owner (group, department, etc.)
storage purpose (backup, old version of operating system, etc.)
HP recommends using end labels as shown in Figure 2-1. End labels reduce the chance of label material interfering with the cartridge shutter and causing a drive to jam.
CAUTION Labels used in the vicinity of the shutter may cause the drive to jam if the label is
installed incorrectly or if portions of the label lift off because of wear. If a drive jams because the label interferes with the shutter, a service call may be necessary.
Figure 2-1 Recommended Placement of Cartridge Labels
2-4 Chapter 2
Page 39
Write-Protecting an Optical Disk
Each side of an optical disk can be write-protected by sliding the write-protect button in the direction of the arrow on the cartridge (see Figure 2-2).
With rewritable optical disks, write-protecting the disk prevents overwriting existing files and prevents any additional file being written to the disk.
With write-once optical disks, existing files cannot be altered or erased regardless of whether or not the write-protect button has been set. However, setting the button to write-protect prevents writing additional files to the disk.

Caring for Optical Disks
Caring for Optical Disks
Follow these guidelines to ensure that your optical disks remain in good condition:
Do not expose disks to extreme magnetic fields.
Do not expose disks to dust particles.
Do not expose disks to extreme temperatures or extreme humidity.
Do not drop the disks.
Do not open a disk's metal shutter and touch the disk surface.
Do not take disks apart.
Do not insert disks with loosely-attached labels into the jukebox.
Remove old disk labels before applying new ones especially if you choose to
place labels on the sides of the cartridge (near the shutter) rather than on the end of the cartridge.
Store disks in a clean, safe place when they are not in use.
Cleaning Disks
Normally, an optical disk does not require cleaning when used in a computer room or clean office environment. If you are in an extremely dusty environment and are experiencing difficulties reading and/or writing to a particular disk you may want to clean the disk to see if this corrects the problem.
CAUTION Be very careful when cleaning an optical disk. Abrasive particles dragged across the
disk surface can damage the disk and prevent recovery of some or all of the data on the disk.
Clean a disk only with a disk cleaning kit. Follow the disk cleaning kit instructions exactly.
HP-approved disk cleaning kits are listed at www.hp.com/go/optical.

CAUTION Turning off the jukebox in the next step could cause data loss if not done correctly.
Do not turn off power to the jukebox until you are sure the SCSI bus is inactive. Removing power from a SCSI device when the bus is active can result in data loss and/or indeterminate bus states. Check your host system manuals for information about checking the SCSI bus status. If your computer is connected to a LAN, be sure to check with your system administrator before turning off power to the jukebox.

Page 58
Operating the Jukebox
Setting the SCSI IDs
NOTE In the next step you will choose a new ID. Review this note.
This jukebox, by default, assigns ID 6 to the jukebox controller. When in LUN mode, the jukebox controller ID uses LUN 0 for itself and assigns the drives on Bus 1 to LUNs 1 to 4 or LUNs 1 to 6 (depending on whether you have four or six drives on Bus 1 in your model of the jukebox).The result is that there are two types of devices (controller and drives) at ID 6.
Some host computer systems do not allow you to assign different device types to the same ID. If your host computer system does not support multiple types at the same ID and you want to use LUN mode, you must select different IDs for the jukebox controller (JKBX ID #) and the drives (DRV #).
Tables in Appendix B show jukebox default settings and an example of setting the jukebox controller and drives to different IDs (one digit apart).
If another device ID is placed between the jukebox controller and the drives, problems can result. For this reason, the jukebox will not accept IDs for the jukebox controller and drives that are more than one digit apart. You will receive a CONFLICT message.
6. Press
NEXT or PREV until the new ID that you want displays and then press
ENTER.
If the jukebox is set to LUN MODE ON, go to Step 8. Only one ID can be changed and the ID automatically updates when you press ENTER.

NOTE When in LUN mode:
If the new ID you choose results in the IDs for the jukebox controller and the drives being more than one digit apart, the jukebox displays CONFLICT and rejects the ID.

A Brief Overview of SCSI
A Brief Overview of SCSI
General
The Small Computer System Interface (SCSI), is a contention-based bus that accommodates different speed devices without impacting the devices with faster transfer speeds. This specification was defined by the American National Standards Institute (ANSI) in 1986. The specification defines both the physical medium and the command set used to transfer information. Later developments are known under the newer specifications, SCSI-2 and SCSI-3.
The SCSI Bus
The common SCSI buses are 50-pin and 68-pin. The 50-pin bus, which uses eight of its lines for data transmission, is called a "narrow" bus. The narrow bus can support eight devices. The 68-pin bus, which uses 16 lines for data transmission is called a "wide" bus. The wide bus can support 16 devices.
Initiators and Targets
SCSI devices on the bus are either “initiators” or “targets.” An initiator (usually the host computer) originates a transaction and the target (usually a peripheral device) fulfills the request.
Initiators and targets identify themselves on the bus by a SCSI ID. The ID is designated by the user and is set electronically or manually depending on the device. In addition to identifying a device on the bus, the ID also determines the priority of the device during contention among the devices for use of the bus.
The narrow SCSI bus, with its eight data lines, can communicate with eight devices that have IDs from 0 to 7. The wide SCSI bus, with its 16 data lines, can communicate with 16 devices that have addresses from 0 to 15. The host adapter, which links the host computer to the SCSI bus, is also a SCSI device (initiator), and is usually assigned an ID of 7.
Priority of IDs ascends from lowest to highest but this ascending priority, however, is in blocks of eight IDs, and the block from 8 to 15 is actually defined to be at a lower priority than ID 0, the lowest address on the "narrow" portion of the bus. This is done so that if a narrow device is placed on a wide bus, the wide devices, which can "see" the lower addresses, will always defer to the lower addresses when they contend for the bus. Otherwise, a narrow device, which cannot "see" any device at
B-2 Appendix B

Operating This Jukebox on a SCSI Bus
A Brief Overview of SCSI
an ID greater than 7, would always assume it won the contention and would attempt to talk, perhaps at the same time as a device with an ID above 7 that was contending for the bus. The following diagram shows the priority scale of IDs when the priority of the two blocks of eight are reversed.

Narrow
Addresses
Wide Address Range
The diagram below shows the linear addressing of a simple, narrow bus with the host adapter set at a SCSI ID of 7. The device ID does not determine where the device is physically placed on the bus.
LUN Addressing
SCSI IDs are the top-level method of addressing devices on the bus. Another method of addressing is also available; logical unit numbering (LUN). This method enables a complex device, such as a jukebox, to group its internal SCSI devices to a single SCSI ID.
The complex device is identified by a SCSI ID, but this complex device assigns logical unit numbers (LUNs) to each device within it. Up to eight LUNs may be assigned under a single SCSI ID. The LUNs that can be assigned are from 0 to 7 (LUN 0 is usually retained by the complex device).
Appendix B B-3
Operation on a
SCSI Bus
Page 92
Operating This Jukebox on a SCSI Bus
A Brief Overview of SCSI
To use this form of addressing, however, the jukebox application software, the SCSI bus drivers and the host adapter firmware all have to support this mode of addressing. The following diagram shows LUNs assigned to devices within the device at ID 6.
Transfer Rates on the Bus
Initially, the SCSI specification defined a 5 MB/s synchronous data transfer rate on the narrow bus. SCSI now also defines "Fast" which is 10 MB/s on a narrow bus and 20 MB/s on a wide bus. Another definition is "Ultra," also known as "Fast-20" which is 20 MB/s transfer rate on a narrow bus and 40 MB/s on a wide bus.
Termination
To keep signals on the SCSI bus from being reflected, “terminators” must be placed at each end of the physical bus. These terminators may be either active or passive. Passive termination is a resistor network. Active termination uses a voltage regulator (the active component) to regulate the power of the resistor network to provide more stable termination. Active termination is always preferred over passive termination.
Depending on your SCSI device, termination is supplied by a using a physical connector, by flipping a dipswitch, or by selecting the termination setting in software.
Termination is always at both physical ends of the bus.
B-4 Appendix B
Page 93
Operating This Jukebox on a SCSI Bus
A Brief Overview of SCSI
Single-ended and Differential Interfaces
The SCSI bus is electrically implemented in two ways: single-ended and differential. These terms come from the way the signals are asserted on the bus. Single-ended buses use a 5-volt signal that is referenced to ground. This method makes the bus somewhat susceptible to noise and loss of signal quality over distance. The maximum allowable length of a single-ended SCSI bus was initially 6 meters (19.7 feet). Fast SCSI required the maximum length of the bus to be reduced to 3 meters (9.8 feet).
The differential bus uses two lines for each signal and measures the voltage difference between the two signals. Differential retains more signal quality than single-ended and is not as sensitive to noise, allowing for a longer cable length. The maximum allowable length of a differential bus is 25 meters (82 feet) for all types buses (narrow, wide, fast, Fast-20).
Connectors
Narrow devices (50-pin) use the following connectors:
50-pin low-density clip Centronics-type (external)
This is a large connector that is similar to a printer cable. This type of connector is gradually being replaced by the Micro D connector, described below.
50-pin high density Micro D (using thumbscrews or small clips) (external)

Wide devices (68- pin) use the following connectors:

This connector is similar to a D-type connector, but longer and slimmer and with smaller pin holes placed closer together. This connector is becoming the most common.

The SCSI Bus and This Jukebox
The SCSI Bus and This Jukebox
This jukebox is a fast and narrow SCSI device with the capability to connect to either a narrow single-ended bus or a wide differential bus.
In the diagram below, note that the single-ended (50-line) bus is brought directly onto the jukebox internal narrow bus. The differential interface accepts a wide bus in its 68-pin connector, but only uses the 50 data and control lines that comprise the "narrow" portion of the bus. The other 18 lines that provide the upper IDs and data of the wide bus are ignored. Note that all lines of the wide bus pass through the two 68-pin differential connectors. The wide bus is maintained as a wide bus.
The single-ended connectors are 50-pin and can accept only a narrow bus. The differential ports use 68-pin connectors and can accept (and pass through) a wide bus.

The SCSI Bus and This Jukebox
Adding Devices to the Bus
When considering adding other devices to the jukebox bus, you should consider the following:
Will adding a device onto a bus with this jukebox interfere or degrade the performance of the jukebox or the device that is added?
If the decision is made to add other devices to the jukebox bus, what SCSI requirements must be observed to make sure the bus will work?
Before addressing some questions involved in deciding whether to place another device on the jukebox bus, we can say that, as a general rule, HP recommends that this jukebox be the only device on a bus. The recommendation is the same whether the bus is single-ended or differential. One reason for the recommendation is that interactions on a SCSI bus can be complicated. The more devices on the bus, the more chance for problems. Another reason is that this jukebox, when fully utilized, is capable of using up the full bandwidth of the bus. Performance of one or all of the devices on the bus can be affected.
Consider the quantity of data that the bus will have to carry, the frequency of data transfer, and the priority of this data transfer in your business. If you are using the jukebox as a backup or archive device, the demands on the jukebox will be different than if the jukebox is used for near-online storage where requests for data are more random in both frequency and amount. If you expect to be using the jukebox at the same time as the other device, or devices, you should expect to experience a drop in performance.
Mixing Wide and Narrow Devices
As a preliminary note to this discussion, HP highly recommends that you do NOT mix wide and narrow buses.
Connecting devices of the same bus width, such as all narrow (50-pin) is a simple process of daisy-chaining the devices, and terminating both ends of the bus. However, mixing narrow and wide devices invites problems.
This method should only be implemented by an experienced systems integrator who is highly knowledgeable about SCSI. Since the wide (68-pin) buses need more data lines on the bus for their data transfer, it's necessary that the cables connecting the devices are 68 pin. The data would be lost if the devices were set up as depicted in the figure below.
B-8 Appendix B
Page 97
Operating This Jukebox on a SCSI Bus
The SCSI Bus and This Jukebox
Because a narrow device only has a 50-pin connector, it will not transmit the eight extra bits of data needed for the wide device on the end of the bus. Using only 50 lines also prevents the narrow device from passing along the IDs of devices at 8 or above.
The lower eight data lines transfer commands and messages, allowing all devices, regardless of size, to co-exist on the bus. However, data transfers and device addressing occur on the higher bits. Since a narrow device can’t "see" the upper 8 data bits, that translates to it not being able to "see" wide devices with a SCSI ID above 8. Remember the host adapter is a device, so if you’re mixing wide and narrow devices on the bus, your host adapter must be at an ID that all devices can address.
If mixing narrow and wide devices is unavoidable, use the configuration described below:

Appendix B B-9
Page 98
Operating This Jukebox on a SCSI Bus
The SCSI Bus and This Jukebox
It is very important that the 68-pin to 50-pin cable is properly configured to assure that the eighteen truncated lines are properly terminated.
Cable Lengths
Observe SCSI cable maximum lengths;
- 3 meters (9.8 feet) for the single-ended bus (remember, this is a fast device)
- 25 meters (82 feet) for the differential bus.
Termination
Refer to the documentation that comes with your particular adapter to see how to apply termination.
Use active terminators to reduce noise sensitivity.
Never terminate the bus at any place except the physical ends. Terminating the
bus in the middle will probably cause the bus to become inoperable or operate in a state that could cause data loss.
If devices are on both sides of the host computer adapter (such as hard drives internal to the host computer and a jukebox external to the host computer) make sure that there is no termination on the host computer adapter. Termination must be only on the device inside the computer that is farthest from the host adapter and the physical device inside the computer, and the last physical device external to the computer.
General
Do not connect a single-ended bus to a differential bus. Damage can occur.
