Preparing the Rack 0
Before starting the StackLink installation, perform the following steps
to prepare the rack for the installation procedure:
1 Verify that the distance between the front and rear mounting strips
is between 25.5 inches and 32.25 inches (650 mm and 820 mm). If
this is not the case, adjust the mounting strips referring to the
instructions provided by the rack manufacturer.
2 Determine the correct placement of the StackLink in the rack (see
figure 1
).
The top mounting tray assembly should be installed in the 1U
space just above where the uppermost library in the system will be
installed.
The bottom mounting tray should be installed as follows:
• If you are installing a 2-high StackLink, allow 8U of space
between the top and bottom mounting tray assemblies. The
entire StackLink mechanism occupies 10U of space, 1U for the
top mounting tray assembly, 8U for libraries, and 1U for the
bottom mounting tray assembly.
• If you are installing a 5-high StackLink, allow 20U of space
between the top and bottom mounting tray assemblies. The
entire StackLink mechanism occupies 22U of space, 1U for the
top mounting tray assembly, 20U for libraries, and 1U for the
bottom mounting tray assembly.
• If you are installing a 10-high StackLink, allow 40U of space
between the top and bottom mounting tray assemblies. The
entire StackLink mechanism occupies 42U of space, 1U for the
top mounting tray assembly, 40U for libraries, and 1U for the
bottom mounting tray assembly.
Note: 1U equals 1.75 inches, or 44.45 millimeters.
Caution: Take rack stability into account when determining
where to place the StackLink. If the M1500 stack will
be the only equipment in the rack, it is recommended
that you install the StackLink at the bottom of the
rack.
