5 Define attributes for individual outputs:
Alternatively, use the context menu to define these parameters for any or all outputs.
6 After you have made the changes you wanted to make, click Update Control Card, at the
bottom of the page, to send your changes to the control card:
7 Each control card in the router must be configured separately and identically.
Either repeat this procedure for each control card in the router . . .
Or, finish making all changes to the control card and then copy its configuration to the
remaining control card(s) in the router. See
Redundant Crosspoint Page
The ‘Redundant Crosspoint’ page has two main functions:
•
Allow remote switching of a router’s redundant crosspoint card (if it has one).
•
Enable or disable automatic switching of the redundant crosspoint module. When auto-
matic switching is enabled and a normal crosspoint card fails, the router’s control card
causes the redundant crosspoint module to take over for the failed crosspoint card.
Normal crosspoint cards can be assigned priority so that if two or more crosspoint cards fail,
the control card will cause the redundant crosspoint module to take over for the normal
crosspoint card of the highest priority.
When switching is automatic, the control card retains the current switchover state even if
power to the router is interrupted.
The left side of the page is for configuration (enabling/disabling automatic fail-over and priori-
tizing the normal crosspoints). You must click ‘Update Control Card’ if you wish to save the
crosspoint configuration.
The right side of the page is “live.” You can click the buttons in the image of the redundant cros-
spoint module to effect redundant crosspoint switchover at any time. The image also reflects
any switchovers effected by other operators.
The ‘Redundant Crosspoint’ page offers an additional capability: it can highlight the inputs and
output slots that correspond to a selected crosspoint card.
