3.13 Audio Routing and AHP Router Modifications
Early Sirius 800 routers must be modified by SAM before they can be used for audio
routing/processing and video processing (see Table 6 to identify your current frame
configuration and the level of routing and processing it is capable of).
Modifications to the router frame are carried out by SAM and include:
• Front and Rear Fans upgraded (blue fan casings)
• Output Module fan door replaced with new door (Sirius 840/850 only)
• Input Module fan door replaced with new door (Sirius 840/850 only)
• Input/Output Module fan door replaced with new door (Sirius 830 only)
• New Control rear panel assembly fitted (Sirius 830 only)
• New Alarm rear panel assembly fitted (Sirius 840/850 only)
• New rating plate fitted
• Nucleus 2450 controllers replaced by Nucleus2 2464 controllers
• Control/fan interface modules replaced by 2457 control/fan interface modules (Sirius
830 only). 2457 Control/fan interface module boards are blue
• Control/fan interface modules replaced by 2458 control/fan interface modules (Sirius
840/850 only). 2458 control/fan interface module boards are blue
• The modifications must be carried out with the router powered down.
• The original shipping bars must not be refitted to a modified frame. The shipping
bars are no longer required as the new fan doors perform the same function.
