Chapter 1 Installing the StackLink
Preparing for the StackLink Installation
Preparing the
Rack
To prepare the rack for the installation procedure:
1
1 Verify that the distance between the front and rear mounting strips is
between 19 inches and 36 inches (483 mm and 914 mm). If this is not
the case, adjusting the mounting strips referring to the instructions
provided by the rack manufacturer.
2 Determine the correct placement of the StackLink in the rack.
Caution:
Take rack stability into account when determining
where to place the StackLink. If the multiple library
stack will be the only equipment in the rack, it is
recommended that you install the StackLink at the
bottom of the rack.
The bottom mounting tray assembly should be installed at the
bottom of the rack.
Note:
The bottom mounting tray assembly occupies 1U of rack
space unless you are installing 3 ATL M2500 libraries in
the rack. In this configuration, the bottom mounting tray
assembly is modified to occupy .5U of rack space.
Note:
1U equals 1.75 inches, or 44 millimeters.
The top mounting tray assembly should be installed as follows:
4
•
If you are installing an 10U StackLink, allow 8U of space between
the top and bottom mounting tray assemblies.
•
If you are installing a 22U StackLink, allow 20U of space between
the top and bottom mounting tray assemblies.
•
If you are installing a 30U StackLink, allow 28U of space between
the top and bottom mounting tray assemblies.
•
If you are installing a 42U StackLink and:
•
Fewer than 3 ATL M2500 library modules, allow 40U of
space between the top and bottom mounting tray assemblies.
•
3 ATL M2500 library modules, allow 40.5U of space between
the top and bottom mounting tray assemblies.

3 Use a pencil to mark the correct position of the mounting tray
assemblies on the rack rails.
4 If the holes in the rack rails are square (untapped), insert caged nuts
(PN YS42008) into the holes where the mounting tray assemblies will
be installed (see figures 1 and 2).
Note:
Install the caged nuts on the back of the rack rails, facing
the interior of the rack.

ATL StackLink™ Installation Instructions
Chapter 2
Installing the
Rack Mount Shelves
2
This chapter explains how to install the ATL M1500 and ATL M2500 rack
mount shelves.
Caution:
When installing the rack mount shelves, keep in mind that
the libraries must be installed contiguously, from the top
of the rack downward, with no space between the
libraries. Due to the way the library firmware calculates
the library size and assigns SCSI element addresses,
installing the libraries non-contiguously can cause
problems with the backup software.
For example, the top library in a multiple library stack
must be installed directly beneath the StackLink upper
mounting tray. Each subsequent library must be installed
directly beneath the previous library, with no space in
between.
For information about how the library firmware calculates
library size and assigns SCSI element addresses, see
appendix A, Library Size, on page 89 and appendix B,
SCSI Element Addressing, on page 95.

Chapter 2 Installing the Rack Mount Shelves
Determining the Position of the Shelves in the Rack
Determining the Position of the Shelves in the Rack
2
Before starting to install the rack mount shelves:
1 Determine the proper position of the shelves in the rack (see
figure 14):
•
Racks are measured in rack mount units. Each unit is called a
“U,” and is equal to 1.75 inches (44.45 millimeters). When you
look at the rack rails, you will notice that the holes are divided
into groups of three, with each group separated by a slightly
smaller space. Each group of three equally spaced holes is one U
(see figure 14).
•
An ATL M1500 library uses 4U of vertical space. The ATL M1500
rack mount shelves must be installed in a full U position (the
bottom of the rack mount shelf must be aligned with the bottom
of a U).
•
An ATL M2500 library uses 13.5U of vertical space. The
ATL M2500 rack mount shelves can be installed in either a full U
or a half U position (the bottom of the rack mount shelf may be
aligned with either the bottom or the middle of a U).
2 Mark the desired shelf position on the rack rails.

In the half U position, the bottom of
the mounting bracket aligns with the
center of the middle hole in the
corresponding U. This position can be
used for ATL M2500 rack mount
shelves only.
In the full U position, the bottom of the
mounting bracket aligns with the
bottom of the corresponding U. This
position can be used for either
ATL M1500 or ATL M2500 rack
mount shelves

To install the rack mount shelves in a full U position:
Note:
The middle library in a 3-high ATL M2500 stack is mounted in
a full U position.
1 From the six sizes of inserts provided in the rack mount kit, select the
appropriate inserts for your rack. The insert part numbers are:
•
213468 (for rails with 9 mm square holes)
•
213469 (for rails with 7 mm diameter unthreaded holes)
•
213471 (for rails with M6 threaded holes)
•
213473 (for rails with 10-32 UNF, 12-24 UNC, or M5 threaded
holes)
•
213474 (for rails with 1/4 inch diameter unthreaded holes)
The heads of the inserts (not the threads) should fit into the holes in
the rack rails smoothly and with very little play.
2 Screw three inserts into the front flange of each rack mount shelf in
positions 1, 4, and 8 (counting from the bottom up, with 1 being the
lowest hole) (see figure 22).
Note:

•
DLT and SDLT cartridges use non-adhesive labels that slide into
a slot at the front of the cartridge. Ensure that the label is fully
inserted into the cartridge label slot.
•
LTO cartridges use adhesive labels that adhere to the front of the
cartridge.

Cleaning cartridge labels are black and white, and their numbers start
with the letters CLN.
Setting the WriteProtect Switch 3
The write-protect switch (see figure 40) controls whether the tape
cartridge is write-protected or write-enabled:
•
Write-protecting a cartridge protects the data it contains from being
erased or overwritten. Typically you use this setting when removing
the cartridges for storage outside the library.
•
Write-enabling a cartridge allows new data to be written to the
cartridge or existing data to be modified or erased. This is the setting
that cartridges are typically set to when they are inside the library.
Setting the Write-Protect Switch (DLT and SDLT Cartridges)

•
Each device on the SCSI bus must have a unique SCSI ID. The default
settings for an ATL M1500 library are: library robotics = 0, tape
drive 1 = 1, tape drive 2 = 2. The default settings for an ATL M2500
library are: library robotics = 0, tape drive 1 = 1, tape drive 2 = 2, tape
drive 3 = 3, tape drive 4 = 4, tape drive 5 = 15, tape drive 6 = 14.
•
Terminator must be provided at each end of the SCSI bus (see
Terminator Power).
•
Do not mix low voltage differential (LVD) and high voltage
differential (HVD) SCSI devices on the same bus. Ensure that the host
adapters match the devices on the bus.
•
All SCSI cables must be shielded or double shielded to meet EMI
specifications.
•
The maximum total SCSI bus length for an LVD SCSI bus is 40 feet
(12 meters).
•
The maximum total SCSI bus length for an HVD SCSI bus is 82 feet
(25 meters).
External terminators must be installed at the end of each SCSI bus. Power
for the terminator must be supplied by at least one device on the SCSI
bus.
In the factory default configuration, the library robotics supplies
terminator power. You can turn this terminator power off using the
Terminator Power option on the GUI Configuration screen.

To configure SCSI import/export elements using the Import/Export
option, you must use the GUI on the GUI master. See the ATL M-Series
Library User’s Guide (PN 6423002) for more information about this option.
Note:
The GUI master is the library module that is connected to the
StackLink motor (see figure 48 on page 69).
Caution:
Although the Import/Export option appears on the GUIs of
all of the library modules, it is only functional on the GUI
master.
Tape Drive SCSI
IDs
5
To set tape drive SCSI IDs, use the GUI on the library module that
contains the tape drives you wish to affect. For example, the addresses of
tape drives installed in library level 2 should be set from the GUI on
library level 2.
Library SCSI
Settings
The SCSI host can be connected to any of the library modules. The SCSI
settings for the multiple library stack (SCSI ID, emulation mode, etc.) are
determined by the settings of the library module that is connected to the
host (the SCSI master).

Appendix A Library Size
Library Size Calculation Examples
The library size reflects the approximate number of cartridge slots in the
multiple library stack. This number is calculated using the following
formula:
Library size = L x C
Where:
•
L = the number of levels between the top of the StackLink and the
lowest library module installed
An ATL M1500 has one level of magazines and so is counted as 1
level. An ATL M2500 has four levels of magazines and so is counted
as 4 levels.
If there is a gap between the top of the StackLink and the lowest
library module installed that is large enough to fit an ATL M1500, the
firmware determines the maximum number of levels that would fit
into the gap, and adds that number of levels to the total.
Note:
•
The method of analyzing the number of levels of the gap
varies, depending on whether the multiple library stack
contains an ATL M2500 (see Library Size in Mixed Stacks
on page 92).
C = the number of cartridge slots in each level
In DLT and SDLT libraries, one level is considered to contain 20
cartridge slots (2 magazines with 10 cartridge slots per magazine).
In LTO libraries, one level is considered to contain 25 cartridge slots
(2 magazines with 12 cartridge slots per magazine, and 1 fixed slot).
Note:
The fixed slot is not included in the calculation of cartridge
slots for DLT and SDLT libraries. This is so the library size
will calculate to a round number.

Figure 62 provides some examples of how the library size is calculated.

An ATL M2500 requires slightly less rack height (13.5U) than four
ATL M1500s (16U). A gap between library modules that is large enough
for an ATL M2500 will only accommodate three ATL M1500s. This means
that the gap can be filled with either 4 library levels (an ATL M2500) or
with 3 library levels (3 ATL M1500s).
In multiple library stacks containing only ATL M1500s, the firmware
assumes that any gaps will be filled with ATL M1500s. Thus a gap large
enough for an ATL M2500 will be treated as space for three ATL M1500s
and will be counted as 3 library levels, not 4 (see figure 63).
In multiple library stacks containing one or more ATL M2500s, the
firmware assumes that a gap large enough for an ATL M2500 will be
filled with an ATL M2500. Thus the gap will be treated as space for 1
ATL M2500 and will be counted as 4 library levels (see figure 63).

In M-Series libraries, SCSI element addressing follows this basic scheme:
•
Drives are assigned consecutive addresses, starting at 80h. If a drive
bay is disabled, it is not assigned a SCSI element address.
•
Data elements are assigned consecutive addresses, starting at C0h.
•
Import/export elements are assigned consecutive addresses, starting
at B0h.

Appendix B SCSI Element Addressing
SCSI Element Addressing in Multiple Library Stacks
SCSI Element Addressing in Multiple Library Stacks
2
In multiple library stacks, SCSI element addresses are assigned starting at
the top of the stack and proceeding downward through the library
modules.
Any gaps between the top of the StackLink and the bottom library
module in the stack that are large enough for a library are assigned the
appropriate number of element addresses, even though there is no library
installed.
Drive bays are assigned SCSI element addresses unless they are disabled.
Disabling a drive bay removes the drive from the element address map.
The import/export function is active only on the library module to which
the StackLink motor is connected. The data element addresses on either
side of the import/export slots are consecutive.
