R FR 5041 Reference Manual. Rev 1.3

The rack frame is designed to fit into industry standard 19” equipment housing. The chassis will
occupy 1 RU of rack space. Open
ing the front cover will allow access to the 19” rack mounting
holes.
Airflow is from side to side, therefore care needs to be taken not to restrict the airflow through the
system. There are no ventilation holes in the top of bottom of the chassis, and no additional rack
space is required to accommodate vertical airflow or ventilation.
Power Supply
The R FR 5041 includes the primary power supply (an optional external power supply
(RPS 5000) can be used for redundancy which will provide a +12VDC input). Should a
power fault develop, the errors are alarmed in the following ways:
Via the LED located on the front of the Power Supply (visible through front cover)
Via a GPO alarm connection to the Termination Panel
Via the LYNX Desktop Controller connected to the LAN port (if used)
If the external redundant power supply (Option RPS 5000) is used then the system will
switch supplies automatically in the event of primary supply failure; with no interruption to
system operation.
The primary power supply is installed and removed from the front of the rack. The supply
locks itself firmly in place. The power supply can be released by pushing up the locking
clip and pulling on the handle above (see below)
