Mounting Configurations
The Hotwire 8820 GranDSLAM chassis comes equipped with mounting brackets
to support installation in 19-inch Electronic Industries Association (EIA)-type or
23-inch NEBS-type racks. Installation of the 8820 chassis in a European
Telecommunication Standards Institute (ETSI)-type rack requires a different set of
custom mounting brackets.
The following figure depicts an example of a chassis mounting configuration with
three chassis in a rack.
8820-A2-GN20-30
CAUTION:
Although three GranDSLAM chassis will fit into one rack, be sure that
after all circuit cards are installed, the final configuration does not
exceed NEBS heat release requirements. NEBS requirements for a rack
of this size is 181.2 watts per square foot. When using a standard
transmission bay (12 inch-deep frame), the footprint is 7 square feet.
This equals 1268 watts maximum per frame or rack when used in a NEBS
location.
NOTE:
In this guide, the term rack refers to a CO rack, cabinet, frame, or bay.
