5.4 Redundant Crosspoint Control
5.4.1 Video Crosspoint Matrix Status Screens
The Main Video Crosspoint Matrix Status screen displays the status of the main and
redundant video crosspoint modules. The Expansion Video Crosspoint Status screen displays
the same information for the expansion video crosspoints (Sirius 850 only). The screens are
also used to switch between video crosspoint modules if a video crosspoint module needs to
be replaced.
Note:
•
The Main Video Crosspoint Matrix Status screen for the Sirius 830 differs from the
Sirius 840 and 850 screen because the Sirius 830 has a maximum of two
crosspoint cards compared with the maximum of five crosspoint modules that can
be fitted to the 840 and 850 routers.
•
The Expansion Video Crosspoint Matrix Status screen displays the expansion
video crosspoint modules in the remote frame (expansion frame) when a dual
frame Sirius 850 system is being used.
•
The operation of the screen is essentially the same for all of the Sirius 800 routers
and is described in this section.
•
For information on replacing a failed crosspoint module see section 10.4.1.
