Attaching TPUs/OCU to the
XDM-300 Shelf
The XDM-300 shelf can be expanded with one or two TPU expansion shelves.
The TPU can be attached on top of the XDM-300 and/or directly under it.
Alternatively, a single OCU expansion shelf can be attached directly on top of
the XDM-300 or on top of a TPU that is installed on the XDM-300.
N
OTE
:
The OCU cannot be installed under the XDM-300
shelf.
When you order an XDM-300 system with one or two TPUs, the shelf is
supplied with the TPUs installed and their fastening brackets attached to each
one. The same applies to OCU shelves.
If your XDM-300 shelf does not include TPU protection, it is possible to
upgrade your system and add one or two TPUs and an OCU at a later stage,
provided you have left space on the rack for this possibility. You need at least
150 mm space above/under the XDM-300 for each TPU/OCU.
The TPUs can be installed without disconnecting any of the XDM-300 cables
and fibers and without affecting traffic not going via a TPU.
