Typical XDM-300 Installation
In addition to the XDM-300 shelf itself, the equipment installed in the rack
includes:
|
One Rack Alarm Panel (RAP) installed at the top of the rack, used to
connect external power and alarm monitoring lines to the XDM-300
shelves installed in the rack. One of the following is suitable:
xRAP-B - fully supports up to two XDM-300 shelves
xRAP-100 - fully supports one XDM-300 shelf and three XDM smaller
shelves (like XDM-100 and XDM-50)
In addition to the space needed for installing the RAP, you must leave at
least 50 mm free space under it for routing cables.
|
Fiber Storage Tray (FST). A separate FST can be installed above each
XDM-300 with optical modules. Each FST contains two storage reels,
enabling the fiber to be stored on the right or left side of the tray. Leave at
least 50 mm free space between the XDM-300 cabling accessories and its
FST, and another 50 mm free between the FST and the next XDM-300
shelf.
|
Cable guide. Two units should be installed, one just above the XDM-300
and one under it, to help neatly route the cables connected to the shelf.
|
Two fiber guides, installed one above the upper cable guide and one under
the lower cable guide. Helps to neatly route fibers, while keeping the
minimum allowed bend radius.
|
Cable slack tray. One unit should be installed under the lower fiber guide,
to help organize the slacks of cables connected to the lower module cage
and lower TPU.
|
xDDF-21 (optional). A separate xDDF-21 panel can be used when
unbalanced 75
