Clearance specifications for the shuttle complex
This topic provides dimensions of a TS3500 Tape Library shuttle complex and
helps you to calculate the required clearances for access and service.
The clearance specifications for a TS3500 Tape Library shuttle complex vary
depending on the selected configuration. Be sure to consider the following items
when designing and installing your shuttle complex:
v
Service and operator clearance around each library string in the shuttle complex
v Height of ceiling and ceiling-mounted appliances
Note:
A minimum ceiling height of 8 feet is required for shuttle complex
installation and service.
v
Fire-suppression system and position of ceiling-mounted sprinkler heads
Figure 21 on page 108 shows a shuttle complex of two parallel six-frame library
strings. The
.
indicates the operator side of the library. As shown, the front doors
of each library string in a shuttle complex must face the same direction.
Variable dimension A , in Figure 21 on page 108, shows the width of the walkway
between library strings. When the short span is ordered (feature code 1850), A can
range from 762 mm (30 in.) to 1 524 mm (60 in.). When the long span is ordered
(feature code 1851),
A can range from 1 524 mm (60 in.) to 2 743 mm (108 in.). A
tolerance of +/− 50 mm (2 in.) can be applied to the maximum dimension of the
short span and the minimum dimension of the long span in order to allow for
flexibility in space planning. Dimension
B
shows the minimum height of the
walkway between connected library strings. This is the distance from the floor to
the bottom of the shuttle connection. Variable dimension
C shows the distance
between shuttle connections. If shuttle connections are mounted on adjacent
frames, the distance between them is 418 mm (16.5 in.). If there are additional
frames between shuttle connections, it is necessary to add 782 mm (30.8 in.) per
interim frame to this figure in order to determine the distance between shuttle
connections. Dimension
D shows the maximum height of the shuttle complex. This
is the maximum distance from the floor to the top of a shuttle connection. Note
that a minimum ceiling height of 8 feet is required for shuttle complex installation
and service.
Although perfect alignment of the two HD frames attached by a shuttle span
results in the best appearance, the two parallel library strings may be slightly offset
in the X-axis. The maximum allowable offset can be determined using the
following formula:
Maximum offset in X = 0.13 x A
For example, if the two parallel library strings are 30 inches apart, the maximum
allowable offset is 3.9 inches.
Each library string in a shuttle complex must also adhere to the operator and
service clearance requirements that are detailed in “Clearance specifications for
models of the Library” on page 103.
