Environmental Considerations
Observe the following guidelines when installing the XDM-300 in racks:
1. Free airflow through the rack must be guaranteed at all times.
2. XDM-300 shelves can be installed in open or closed (with door) racks.
When installed in a closed rack, the door must be perforated. An example
of a rack with a perforated door is the ETSI A rack shown in the following
figure.
3. Always install the first XDM-300 shelf in the lower part of the rack,
leaving a space of at least 1U from the bottom of the rack.
4. In mixed (horizontal and vertical airflow) equipment installations, always
install the equipment with the horizontal airflow (for example, XDM-300)
in the lower part of the rack, and the equipment with the vertical airflow
(for example, XDM-1000) above it.
5. Leave a space of at least 1U between the upper accessory of the XDM-300
and the next shelf.
6. Leave as much space as possible between the rack’s cable supports and the
XDM-300 sidewalls.
7. Always consider the shelf airflow requirements when organizing the cable
and fiber routes near the XDM-300 sidewalls.
