3.7.2 Intelligent Detector Backplane in ST900 Large Outercase
When a ST900 Larger Outercase is specified, a 19” Swing Frame will be required and one or
more 19” Rack Assemblies. The Intelligent Detector Backplanes will be mounted as shown in
Figure 21. The maximum number of Detector Cards which can be specified is eight. The items
that should be ordered for this configuration are listed Figure 22. For information on the
connectivity please refer to paragraph 3.7. If a Freestanding TC12 OTU has been specified at
some stage then the 19” Rack Assembly will need to be positioned or moved to the secondary
position, show in Figure 5.
Figure 21
Warning! Figure 21 shows a Gemini unit, full configuration, details of which are detailed
later in this document. It is important that the Gemini Last Gasp Dial Battery, within the
Gemini Power Supply Unit, is orientated correctly; the battery terminal must be facing up.
If the unit is to be mounted in such a way that the battery terminals are not facing up then it is
necessary to implement certain modifications to ensure that the battery is not operating upside
down. Please refer to document 667/HB/32600/000 for the necessary modifications.
