DSPbR Series – User’s Manual
Document Number 00000.B Page 37/75
The DSPbR is designed to be mounted within a 19-inch rack frame within an indoor environment. Although the
mechanical strength of the DSPbR sub rack frame is robust enough to contend with a maximum “all up” module
load, any additional weight bearing adjustable mechanical supports such as angle brackets extending between
the 19-inch front mounting frame and a rear frame would add strength to the support. There are many types of
19” rack cabinets and we suggest you consult with your 19” rack frame or cabinet supplier for appropriate
weight support options.
The DSPbR uses forced air cooling and requires good airflow from the front of the DSPbR where the two fans
draw in cooler air and expel heated air at the rear. 19-inch rack cabinet ventilation must facilitate the
unrestricted movement of cooler air from the front of the cabinet and the unrestricted movement of expelled hot
air at the rear. The fan speeds are temperature controlled, alarm notification messages and hardwired state
change critical alarm relay contacts will activate if the temperature exceeds safe operational limits.
