7.1 Main Video Crosspoint Matrix Status

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 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.
