Air Flow - Rear Isometric view
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. With the top rack
installed, air flows from the top of the library through a 2-inch gap in the bottom
of the top rack. Internal components in the top rack must be mounted so that they
do not interfere with the air flow through the 2-inch gap in the bottom of the top
rack. The rear door of the top rack is perforated to allow the hot air to exit.
Note: 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.
Powering the components within the frame
The TS4500 tape library connects to AC power in multiple ways. The library is
powered by two AC to DC power supplies in the Lx5 frame. You can also have
power supplies that are installed in a Dx5 frame.
Powering the components within the frame
The Frame Control Assembly (FCA) includes power supplies for the tape drives
that are installed in the frame. All Lx5 frames ship with an FCA. For Dx5 models,
FC 1450 provides an FCA. If you have tape drives in a Dx5 frame, then FC1450 is
required in that frame. The frame power supply provides power to the drives and
control cards within that frame. A single power supply is adequate to power the
frame, but two power supplies are present for redundancy. Any of the AC to DC
