Power and cooling requirements
This section introduces the power and cooling specifications for the two power
structures that are used by TS3500 Tape Library frames.
Power and cooling for components of the TS3500 Tape Library are provided by the
frame in which they are housed. The two power structures are the frame control
assembly, which is used by models L22, D22, L32, D32, L52, and D52, and the
enhanced frame control assembly, which is used by models L23, D23, L53, and
D53.
Power and cooling specifications for Models L22, D22, L32,
D32, L52, and D52
This section gives an overview of the power and cooling requirements of Models
L22, D22, L32, D32, L52, and D52 of the TS3500 Tape Library.
For models L22, D22, L32, D32, L52, and D52, each base frame and each expansion
frame that contains drives has its own frame control assembly (FCA). The FCA
receives ac power from a customer-supplied outlet and, in turn, provides ac power
to all tape drives within the frame. The FCA and tape drives have their own
cooling as part of their packages, but air must be allowed to flow freely from the
top of the library.
Note:
In order for air to flow freely from the top of the library, do not stack
cartridges, books, or other materials on the top of the library.
For redundancy, the FCA in the base frame (models L22, L32, or L52) contains two
dc power supplies for the accessor. As an option, an additional dc power supply
for the accessor can be added to any expansion frame (models D22, D32, or D52)
that has an FCA installed. The FCA is not required in expansion frames that
contain no tape drives.
Each frame receives single-phase (200–240 V ac) power on its own power cord
from a customer-supplied outlet.
Countries in North America have the option of operating at 100–127 V ac power. In
addition, each frame also has the option of receiving ac power from two
independent line cords (feature code 1901). For more information about these
options, refer to the following topics:
v
“Power cords for Models L32 and D32” on page 124
v
“Power cords for Models L22, D22, L52, and D52” on page 127
For libraries that include a second accessor and the high-availability Model HA1,
at least one D22, D32, or D52 frame (not a service bay) must be equipped with a
frame control assembly (feature code 1452 for Model D32 or feature code 1453 for
Models D22 and D52). In addition, and at least one additional 37 V dc power
supply (feature code 1902 is required. It is recommended that, where possible, you
order two 37 V dc power supplies (feature code 1902) plus a dual line cord (feature
code 1901) for each L-frame and D-frame with an FCA.
